Cast On Critical Strike Support

Causes a linked spell to activate when the player rolls a critical strike with the attack skill it is linked to.

The chance to cast is rolled separately for each enemy you scored a critical hit on, so it is possible to get multiple casts on one skill use if you hit multiple enemies and are lucky enough.

In case of multiple spells linked to one attack skill this support will roll its chance to cast for each spell separately, so it's possible to cast either one of them, both, or none.

Skill Functions and Interactions

Cooldown Time: When a supported spell is successfully cast, it and all supported spells of the same name are put on cooldown for 10 milliseconds. This means that a given spell can only trigger once per critical strike, and reduces the effect of linking multiple copies of the same spell to this support (especially when it is at a higher gem level). It is important to note that this cooldown does not apply to the gem as whole; you can trigger multiple spells within the 10 millisecond cooldown time as long as they are different.
