Cast when Stunned Support

CastOnStunCast when Stunned Support is a Support gem that causes a linked Spell to Trigger when the player is stunned or blocks a stunning hit.

Skill functions and interactions

Cast when Stunned targets the enemy which stunned the player. Spells that don't have targeting, like Discharge or Ice Nova, will be cast on the character as usual.

When the character is stunned or blocks a stunning hit, the chance to activate supported spells is rolled individually for each linked spell, then all the spells that succeeded this chance check will activate at once. Multiple copies of the same spell cannot activate at the same time, only one can, however linking multiple copies of the same spell increases the chance that at least one of them activates.

After that the global CwS cooldown occurs, which is currently 250ms. Getting stunned during cooldown time will not cause any supported spells to activate, even if you have multiple CwS groups.

Strategy

Versus CastOnDmgTakenCast when Damage Taken Support

Cast when Stunned has several advantages, which may tip its balance in its favour, depending on your character's build:

  • Characters who use energy shield or heroicspiritMind Over Matter will typically have more hit points than their Life pool (for purposes of stunning). This also results in more stuns per damage taken.

  • Unlike CastOnDmgTakenCast when Damage Taken Support , Cast when Stunned does not suffer a damage penalty at any level. However, it is usually still ineffective for damage-dealing purposes.

  • Most importantly, Cast when Stunned does not have a limit on active skill level. This makes it a better choice for level-dependent skills, since the trigger damage for CastOnDmgTakenCast when Damage Taken Support increases rapidly with level.
