Cast on Critical Strike (commonly referred to as CoC) is a support gem that causes linked spells to trigger when the player critically strikes with a linked attack skill.

Skill functions and interactions

Supporting multiple spells

If more than one spell is supported by Cast on Crit Support, the order of the triggered spells will follow the trigger order. (Successive triggers cycle through all valid supported spells in a predictable order)

When a supported spell is successfully triggered, all spells with the same name supported by that Cast on Crit Support are placed on cooldown. This prevents multiple copies of the same spell from being triggered sequentially.

Effective cooldown & cooldown thresholds

Due to how server ticks are calculated, there are breakpoints of cooldown recovery rates required to achieve a higher effective trigger rate.[1]. Additional CDR that does not reach the next threshold is wasted.

The attack rates below are maximums; exceeding the attack rates even slightly can significantly reduce proc rate due to skipping procs while the skill is still on cooldown. It is better to be slightly below the attack rate than above it. Note that multiples of the attack rate also work (e.g. 12.12 APS will proc at the same rate as 6.06 APS).
