Spell damage is all damage which is not dealt by physical attacks. This includes all spells which deal magical, physical or pure damage, as well as all items with abilities that deal damage. Even the damage dealt by attack modifiers counts as spell damage, as long as the effect deals its damage in a separate instance from the attack damage.

Magic spell damage is influenced by magic resistance, physical spell damage is influenced by armor and pure damage is not affected by either. All three underlie damage manipulation.

Sources of spell damage[edit]

Spell damage amplification[edit]

Spell damage can be directly amplified. Spell damage amplification of multiple sources stacks additively. The amplification does not only affect spell damage dealt against enemies, it also causes damage afflicted to allies or the own unit to get amplified.

Spell amplification granting items[edit]

Many items grant their owners a spell damage amplification bonus by giving them a direct bonus. The effects are limited to the item's owner, which must have the item equipped.

Unaffected by amplification[edit]

There are certain cases of abilities that ignore spell amplification. It is important to note that those spells cannot spell lifesteal either.

In general abilities related to health manipulation (instantly killing effect, health cost, delayed damage) and regular attacks (cleave, instant attacks, Moon Glaives) do not benefit from spell amplification. The exceptions to this rule are splash, Tree Grab, and Psi Blades which are still amplified.

Damage dealt by a summon is affected by the summon's spell amplification, not by the summoner's spell amplification (e.g. Death Ward).

The following abilities are not affected by spell amplification (excluding abilities where the aforementioned general rules apply):

Version history[edit]

  • Damage return from Blade Mail is no longer increased by Spell Amplification
  • Moon Glaives no longer gets boosted by Spell Amplification.
  • Cleave no longer gets boosted by Spell Amplification.
  • Spell Lifesteal does not trigger heal for things that don't receive spell amplification (Moon Glaives, Cleave).
