 * Note that most of the information below applies to the PnP version of Dungeons & Dragons, and thus may be incorrect or irrelevant for DDO. See Spells for the complete list of spells in DDO. See also the spells category for a more organized list.

A spell is a one-time magical effect. Spells come in two types: arcane spells (cast by bards, sorcerers, and wizards) and divine spells (cast by clerics and experienced paladins and rangers). Some spellcasters select their spells from a limited list of spells known, while others have access to a wide variety of options.

Despite these different ways that characters use to learn or prepare their spells, when it comes to casting them, the spells are very much alike.

Level
A number that defines the spell's relative power. Spell levels range from 1 to 9 for dedicated spellcasting classes. The maximum is lower for classes with minor casting ability.

A spell's level determines its spell point cost and affects the Difficulty Class for any saving throw allowed against its effects. A spell's level does not reflect the level at which it can be cast. It takes generally takes spellcasting classes two or three character levels to gain access to each new level of spells.

Schools
Cutting across the categories of arcane and divine spells are the eight schools of magic. These schools represent the different ways that spells take effect.

Every spell belongs to one of eight schools of magic. A school of magic is a group of related spells that work in similar ways.
 * Abjuration
 * Conjuration
 * Divination
 * Enchantment
 * Evocation
 * Illusion
 * Necromancy
 * Transmutation

Descriptor
Some spells have a descriptor that further categorizes the spell in some way. Descriptors generally depend on the spell's effects in a straightforward way. For example, a spell that causes sonic damage is usually a "sonic spell". Some spells have more than one descriptor.

The descriptors are acid, chaotic, cold, death, electricity, evil, fear, fire, force, good, healing, language-dependent, lawful, light, negative, mind-affecting, repair, and sonic.

Most of these descriptors have no game effect by themselves, but they govern how the spell interacts with other spells, with special abilities, with unusual creatures, with alignment, and so on.

A mind-affecting spell works only against intelligent, living creatures with an intelligence score of 1 or higher.

Casting Spells
Whether a spell is arcane or divine, and whether a character prepares spells in advance from a larger list or knows a small list that is always completely prepared, casting a spell works the same way.

To cast a spell, you must be able to speak (if the spell has a verbal component), gesture freely (if it has a somatic component), and have the right material component in your inventory (if the spell needs one).

Casting a spell reduces your spell points, which do not regenerate on their own. You must return to the city or a tavern, or find a rest shrine, to regain your spell points. Alternatively, a Potion of Mnemonic Enhancement or the Cleric enhancement Divine Vitality can partially restore spell points.

Concentration
If you take damage while trying to cast a spell, you must make a concentration check (DC 10 + points of damage taken + the level of the spell you're casting). If you fail the check, you lose the spell without effect.

Caster Level
A spell's power often depends on its caster level, which for most spellcasting characters is equal to your class level in the class you're using to cast the spell.

In the event that a class feature, domain granted power, or other special ability provides an adjustment to your caster level, that adjustment applies not only to effects based on caster level (such as, duration, and damage dealt) but also to your caster level check to overcome your target's spell resistance and to the caster level used in dispel checks (both the dispel check and the DC of the check).

Spell Failure
If you ever try to cast a spell in conditions where the characteristics of the spell cannot be made to conform, the casting fails and the spell is wasted.

Spells also fail if your concentration is broken and might fail if you're wearing armor while casting an arcane spell with somatic components.

Armor Spell Failure Chance
Shields and suits of armor have a chance of causing arcane spell failure - complete failure of a spell due to difficulty performing the intricate gestures it needs. This does not apply to divine spells or to spells that don't have a somatic component. Bards ignore the ASF penalty from light armor (though not from shields).

You may find the arcane spell failure chance for each armor in its description.

Spell Result
Once you know which creatures (or objects or areas) are affected, and whether those creatures have made successful saving throws (if any were allowed), you can apply whatever results a spell entails.

Special Spell Effects
Many special spell effects are handled according to the school of the spells in question. Certain other special spell features are found across spell schools.


 * Attacks
 * Some spell descriptions refer to attacking. All offensive combat actions, even those that don't damage opponents are considered attacks. Attempts to turn undead count as attacks. All spells that opponents resist with saving throws, that deal damage, or that otherwise harm or hamper subjects are attacks. Spells that summon monsters or other allies are not attacks because the spells themselves don't harm anyone.


 * Bonus Types
 * Usually, a bonus has a type that indicates how the spell grants the bonus. The important aspect of bonus types is that two bonuses of the same type don't generally stack. With the exception of dodge bonuses, most circumstance bonuses, and racial bonuses, only the better bonus works. The same principle applies to penalties?a character taking two or more penalties of the same type applies only the worst one.

Stacking Effects
Spells that provide bonuses or penalties on attack rolls, damage rolls, saving throws, and other attributes usually do not stack with themselves. More generally, two bonuses of the same type don't stack even if they come from different spells.


 * Different Bonus Names
 * The bonuses or penalties from two different spells stack if the modifiers are of different types. A bonus that doesn't have a type stacks with all other bonuses.


 * Same Effect More than Once in Different Strengths
 * In cases when two or more identical spells are operating in the same area or on the same target, but at different strengths, only the best one applies.


 * Same Effect with Differing Results
 * The same spell can sometimes produce varying effects if applied to the same recipient more than once. Usually the last spell in the series trumps the others. None of the previous spells are actually removed or dispelled, but their effects become irrelevant while the final spell in the series lasts.


 * One Effect Makes Another Irrelevant
 * Sometimes, one spell can render a later spell irrelevant. Both spells are still active, but one has rendered the other useless in some fashion.


 * Multiple Mental Control Effects
 * Sometimes magical effects that establish mental control render each other irrelevant, such as a spell that removes the subjects ability to act. Mental controls that don't remove the recipient's ability to act usually do not interfere with each other. If a creature is under the mental control of two or more creatures, it tends to obey each to the best of its ability, and to the extent of the control each effect allows. If the controlled creature receives conflicting orders simultaneously, the competing controllers must make opposed charisma checks to determine which one the creature obeys.

Spells with Opposite Effects
Spells with opposite effects apply normally, with all bonuses, penalties, or changes accruing in the order that they apply. Some spells negate or counter each other. This is a special effect that is noted in a spell's description.


 * Instantaneous Effects
 * Two or more spells with instantaneous durations work cumulatively when they affect the same target.

Components
A spell's components are what you must do or possess to cast it. The Components entry in a spell description includes abbreviations that tell you what type of components it has. Specifics for material, focus, and XP components are given at the end of the descriptive text. Usually you don't worry about components, but when you can't use a component for some reason or when a material or focus component is expensive, then the components are important.


 * Verbal (V)
 * A verbal component is a spoken incantation. To provide a verbal component, you must be able to speak in a strong voice. A silence spell or a gag spoils the incantation (and thus the spell).


 * Somatic (S)
 * A somatic component is a measured and precise movement of the hand. You must have at least one hand free to provide a somatic component.


 * Material (M)
 * A material component is one or more physical substances or objects that are annihilated by the spell energies in the casting process.

Range
A spell's range indicates how far from you it can reach, as defined in the range entry of the spell description. A spell's range is the maximum distance from you that the spell's effect can occur, as well as the maximum distance at which you can designate the spell's point of origin for targetable area-effect spells.

Attempting to cast a spell on a target beyond the spell's range expends the spell anyway, and is usually a waste. If it's an AoE spell, it still affects any legal targets that happen to be in its affected area. Spell targets that move during casting are affected based on where they are when the spell finishes, not where they were when it started.

Some common special target ranges include the following.


 * Self
 * The spell affects only you.


 * Touch
 * The target must be within melee range.

Effect
Some spells create or summon things rather than affecting things that are already present.

You must designate the location where these things are to appear, either by seeing it or defining it. Range determines how far away an effect can appear, but if the effect is mobile it can move regardless of the spell's range.


 * Ray
 * Some effects are rays. You aim a ray as if using a ranged weapon, though typically you make a ranged touch attack rather than a normal ranged attack. As with a ranged weapon, you can fire into the dark or at an invisible creature and hope you hit something. You don't have to see the creature you're trying to hit, as you do with a targeted spell. Intervening creatures and obstacles, however, can block your line of sight or provide cover for the creature you're aiming at.


 * If a ray spell has a duration, it's the duration of the effect that the ray causes, not the length of time the ray itself persists.


 * If a ray spell deals damage, you can score a critical hit just as if it were a weapon. A ray spell threatens a critical hit on a natural roll of 20 and deals double damage on a successful critical hit.


 * Spread
 * Some effects, notably clouds and fogs, spread out from a point of origin, which must be a grid intersection. The effect can extend around corners and into areas that you can't see. Figure distance by actual distance traveled, taking into account turns the spell effect takes. When determining distance for spread effects, count around walls, not through them. As with movement, do not trace diagonals across corners. You must designate the point of origin for such an effect, but you need not have line of effect (see below) to all portions of the effect.

Area
Some spells affect an area. Sometimes a spell description specifies a specially defined area, but usually an area falls into one of the categories defined below.

Regardless of the shape of the area, you select the point where the spell originates, but otherwise you don't control which creatures or objects the spell affects. The point of origin of a spell is always a grid intersection. When determining whether a given creature is within the area of a spell, count out the distance from the point of origin in squares just as you do when moving a character or when determining the range for a ranged attack. The only difference is that instead of counting from the center of one square to the center of the next, you count from intersection to intersection.

You can count diagonally across a square, but remember that every second diagonal counts as 2 squares of distance. If the far edge of a square is within the spell's area, anything within that square is within the spell's area. If the spell's area only touches the near edge of a square, however, anything within that square is unaffected by the spell.


 * Burst, Emanation, or Spread
 * Most spells that affect an area function as a burst, an emanation, or a spread. In each case, you select the spell's point of origin and measure its effect from that point.


 * A burst spell affects whatever it catches in its area, even including creatures that you can't see. It can't affect creatures with total cover from its point of origin (in other words, its effects don't extend around corners). The default shape for a burst effect is a sphere, but some burst spells are specifically described as cone-shaped. A burst's area defines how far from the point of origin the spell's effect extends.


 * An emanation spell functions like a burst spell, except that the effect continues to radiate from the point of origin for the duration of the spell. Most emanations are cones or spheres.


 * A spread spell spreads out like a burst but can turn corners. You select the point of origin, and the spell spreads out a given distance in all directions. Figure the area the spell effect fills by taking into account any turns the spell effect takes.


 * Cone, Cylinder, Line, or Sphere
 * Most spells that affect an area have a particular shape, such as a cone, cylinder, line, or sphere.


 * A cone-shaped spell shoots away from you in a quarter-circle in the direction you designate. It starts from any corner of your square and widens out as it goes. Most cones are either bursts or emanations (see above), and thus won't go around corners.


 * When casting a cylinder-shaped spell, you select the spell's point of origin. This point is the center of a horizontal circle, and the spell shoots down from the circle, filling a cylinder. A cylinder-shaped spell ignores any obstructions within its area.


 * A line-shaped spell shoots away from you in a line in the direction you designate. It starts from any corner of your square and extends to the limit of its range or until it strikes a barrier that blocks line of effect. A line-shaped spell affects all creatures in squares that the line passes through.


 * A sphere-shaped spell expands from its point of origin to fill a spherical area. Spheres may be bursts, emanations, or spreads.

A spell with this kind of area affects creatures directly (like a targeted spell), but it affects all creatures in an area of some kind rather than individual creatures you select. The area might be a spherical burst, a cone-shaped burst, or some other shape.
 * Creatures

Many spells affect "living creatures," which means all creatures other than constructs and undead. Creatures in the spell's area that are not of the appropriate type do not count against the creatures affected.


 * Objects
 * A spell with this kind of area affects objects within an area you select (as Creatures, but affecting objects instead).

Line of Effect
A line of effect is a straight, unblocked path that indicates what a spell can affect. A line of effect is canceled by a solid barrier. It's like line of sight for ranged weapons, except that it's not blocked by fog, darkness, and other factors that limit normal sight.

You must have a clear line of effect to any target that you cast a spell on or to any space in which you wish to create an effect. You must have a clear line of effect to the point of origin of any spell you cast.

A burst, cone, cylinder, or emanation spell affects only an area, creatures, or objects to which it has line of effect from its origin (a spherical burst's center point, a cone-shaped burst's starting point, a cylinder's circle, or an emanation's point of origin).

An otherwise solid barrier with a hole of at least 1 square foot through it does not block a spell's line of effect. Such an opening means that the 5-foot length of wall containing the hole is no longer considered a barrier for purposes of a spell's line of effect.


 * Duration
 * A spell's duration entry tells you how long the magical energy of the spell lasts.


 * Timed Durations
 * Many durations are measured in rounds, minutes, hours, or some other increment. When the time is up, the magic goes away and the spell ends. If a spell's duration is variable the duration is rolled secretly (the caster doesn't know how long the spell will last).


 * Instantaneous
 * The spell energy comes and goes the instant the spell is cast, though the consequences might be long-lasting.


 * Concentration
 * The spell lasts as long as you concentrate on it. Concentrating to maintain a spell is a standard action that does not provoke attacks of opportunity. Anything that could break your concentration when casting a spell can also break your concentration while you're maintaining one, causing the spell to end.


 * You can't cast a spell while concentrating on another one. Sometimes a spell lasts for a short time after you cease concentrating.


 * Subjects, Effects, and Areas
 * If the spell affects creatures directly the result travels with the subjects for the spell's duration. If the spell creates an effect, the effect lasts for the duration. The effect might move or remain still. Such an effect can be destroyed prior to when its duration ends. If the spell affects an area then the spell stays with that area for its duration.


 * Creatures become subject to the spell when they enter the area and are no longer subject to it when they leave.


 * Discharge
 * Occasionally a spells lasts for a set duration or until triggered or discharged.


 * (D) Dismissible
 * If the duration line ends with "(D)," you can dismiss the spell at will. You must be within range of the spell's effect and must speak words of dismissal, which are usually a modified form of the spell's verbal component. If the spell has no verbal component, you can dismiss the effect with a gesture. Dismissing a spell is a standard action that does not provoke attacks of opportunity.


 * A spell that depends on concentration is dismissible by its very nature, and dismissing it does not take an action, since all you have to do to end the spell is to stop concentrating on your turn.

Saving Throw
Usually a harmful spell allows a target to make a saving throw to avoid some or all of the effect. The saving throw entry in a spell description defines which type of saving throw the spell allows and describes how saving throws against the spell work.


 * Negates
 * The spell has no effect on a subject that makes a successful saving throw.


 * Partial
 * The spell causes an effect on its subject. A successful saving throw means that some lesser effect occurs.


 * Half
 * The spell deals damage, and a successful saving throw halves the damage taken (round down).


 * None
 * No saving throw is allowed.


 * Disbelief
 * A successful save lets the subject ignore the effect.


 * (object)
 * The spell can be cast on objects, which receive saving throws only if they are magical or if they are attended (held, worn, grasped, or the like) by a creature resisting the spell, in which case the object uses the creature's saving throw bonus unless its own bonus is greater. (This notation does not mean that a spell can be cast only on objects. Some spells of this sort can be cast on creatures or objects.) A magic item's saving throw bonuses are each equal to 2 + one-half the item's caster level.


 * Saving Throw Difficulty Class
 * A saving throw against your spell has a DC of 10 + the level of the spell + your bonus for the relevant ability (Intelligence for a wizard, Charisma for a sorcerer or bard, or Wisdom for a cleric, paladin, or ranger). A spell's level can vary depending on your class. Always use the spell level applicable to your class.


 * Succeeding on a Saving Throw
 * A creature that successfully saves against a spell that has no obvious physical effects feels a hostile force or a tingle, but cannot deduce the exact nature of the attack. Likewise, if a creature's saving throw succeeds against a targeted spell you sense that the spell has failed. You do not sense when creatures succeed on saves against effect and area spells.


 * Automatic Failures and Successes
 * A natural 1 (the d20 comes up 1) on a saving throw is always a failure, and the spell may cause damage to exposed items. A natural 20 (the d20 comes up 20) is always a success.

Spell Resistance
Spell resistance is a special defensive ability. If your spell is being resisted by a creature with spell resistance, you must make a caster level check (1d20 + caster level) at least equal to the creature's spell resistance for the spell to affect that creature. The defender's spell resistance is like an armor class against magical attacks. Include any adjustments to your caster level to this caster level check.

The spell resistance entry and the descriptive text of a spell description tell you whether spell resistance protects creatures from the spell. In many cases, spell resistance applies only when a resistant creature is targeted by the spell, not when a resistant creature encounters a spell that is already in place.

The terms "object" and "harmless" mean the same thing for spell resistance as they do for saving throws. A creature with spell resistance must voluntarily lower the resistance (a standard action) in order to be affected by a spell noted as harmless. In such a case, you do not need to make the caster level check described above.
