Hit point

Hit points, also known as health points (or HP), damage points, or just health (among other synonyms), is a finite value used to determine how much damage (usually in terms of physical injury) a character can withstand. When a character is attacked, or is hurt from a hazard or fall, the total damage dealt (which is also represented by a point value) is subtracted from their current HP. Once their HP reaches 0, the character will fall unconscious and be unable to fight. In DDO, health is often abbreviated by two letter initialisms such as HP.

Increasing Hit Points
Hit points increase by themselves when you level up. That increase is not equal for everyone and depends on many factors. However, everyone benefits from the bonus 20 HP from the free Heroic Durability feat received at creation.

Class
For each level, you gain hit points depending on the class you take that level in.


 * Artificer: 6 hit points
 * Barbarian: 12 hit points
 * Bard: 6 hit points
 * Cleric: 8 hit points
 * Favored Soul: 8 hit points
 * Fighter: 10 hit points
 * Monk: 8 hit points
 * Paladin: 10 hit points
 * Ranger:8 hit points
 * Rogue: 6 hit points
 * Sorcerer: 4 hit points
 * Wizard: 4 hit points

Constitution
On each level, your Constitution modifier is modified according to your level*mod and added to your hp. This is no static value and may change according to how your modifier changes because of buffs and debuffs on your constitution; negative modifiers count as 0.

At level 20, it is 20 hp per 2 constitution over 10 constitution. For example 22 con at level 20 gives you 6*20 hp for a total of 120 hp. ((22-10)/2)*20

Toughness Feat
The Toughness feat adds 3 hit points to the character, plus 1 per level. This feat can be taken multiple times, and the bonuses stack.

Prerequisite: None

Toughness Enhancements
After taking Toughness, you may increase its benefits by taking the Toughness Enhancement that is available to several classes and races.

Other bonuses

 * Certain prestige enhancements grant a hit point bonus, e.g. Bard Warchanter II, Artificer Battle Engineer I, Fighter Stalwart Defender, or Paladin Defender of Siberys
 * Toughness item enchantment gives 20 hp that stacks with all other bonuses
 * Green Steel accessories can give + 10/15/20 hp for a total of 45 hp across the three tiers (Elemental Energy).
 * A guild augment Crystal of Health stacks for an additional 5/10/15/20 hp, depending on size.

Temporary Hit Points
Some effects award a character additional, special hp called temporary hit points. Any damage the character suffers that would normally affect his real hp applies to his temporary hp first. As their name implies, they don't last forever -- only until they're used up or the buff that granted them wears off. Temporary hp appear as a number with a "+" sign, in parentheses, after the character's real hp count on top of his red hp bar.

Bonuses and penalties that affect healing amounts do not affect temporary hit point gains.
