Spell damage is all damage which is not dealt by physical attacks. This includes all spells which deal magical, physical or pure 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 amplification[edit]

Spell damage can be directly amplified. Each point of Intelligence attribute symbol.png Intelligence increases a hero's spell damage by 0.07%, which equates to 1% spell damage for every 14 points of intelligence. 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.

Currently there is no unit ability that directly amplifies spell damage, but a couple of heroes have perks in the talents tree.

Spell damage increasing abilities

These items passively increase the owner's spell damage amplification by merely having them equipped. They either grant a flat bonus, or bonus through intelligence.

Unaffected by amplification[edit]

There are certain cases of abilities that ignore spell amplification. It's important to note that those spells cannot spell lifesteal, too.

In general abilities related to health manipulation (instantly killing effect, health cost, delayed damage) abilities and or regular attacks (cleave, instant attacks) don't benefit from spell amplification as well. The exceptions to this rule are splash and Psi Blades icon.png Psi Blades which are still amplified.

Version history[edit]

Version
Description
  • Moon Glaive 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 Glaive, Cleave).
