Spell power displayed on the character screen - hover over the icon

Spell power rating determines how much damage you deal with spells. In most cases, each point of spell power increase increases the base damage of your spell by 1%. Various effects can contribute to your spell power, all effects are added together.

Spell power was introduced in Update 14 and replaced previous spell damage amplification that involved addition and multiplication.

Spell power applies only to spells that cause hit point damage and spells that heal hit points.

Spell power affects Spells and SLAs, but does not affect magical damage effects on weapons from augments, filigrees, crafted enchantments etc. unless the description specifically indicates that it does

• e.g. +1d6 Light Damage per hit from a crafted Coruscating effect is +1d6 at 0 Light spell power and still +1d6 at 100 Light spell power

Spellpower can apply to most Imbue effects on weapons.

Spellpower only affects your own spells or SLAs, it does not affect spells that you cast from scrolls, wands, clickies, etc.

Sources of spell power

Universal Spell Power

• Fully stacking. It flat adds to all of your other Spell Powers; in the summary screen popup (demonstrated in the image to the upper right) the Spell Powers you see for specific elements are the final value after your Universal Spell Power has been added to all of your other enhancements to that power type.

• Everything fully stacks

Standard magic items

• Equipment bonus from items with enchantments like Potency or Combustion. The item enchantment name corresponds to the type of spells the spell power applies to. The equipment bonus on randomly generated loot increases on higher level equipment. (See Thaumaturgy for an overview table.)
