Spell Immunity

From Liquipedia Dota 2 Wiki
Fear nothing!

Spell Immunity is a buff that prevents the targeting of many spells and grants 100% Magic Resistance. Most ultimate abilities will pierce spell immunity in some way, either through damage, status effects, or both.

This mechanic was formerly known as Magic Immunity until it was reworked in patch 6.82. The difference now is to clarify that Spell Immunity can cause units to be immune to spells regardless of that spell's damage type. Even Physical damage spells may be blocked by Spell Immunity now. One of the main changes caused by this rework also allows some Pure damage spells to pierce Spell Immunity.

Abilities that fully pierce Spell Immunity[edit]

Note that any magical damage is still blocked. All the effects (such as disables) will pierce Spell Immunity.
