Cast On Critical Strike Support
Template:Gem Infobox Cast on Critical Strike (commonly referred to as "CoC") is a trigger gem that 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.

Quest reward

Strategy
Linking with other skills
At a bare minimum, a Cast On Critical Strike setup will require three gems: an attack, Cast On Critical Strike itself, and a spell to be triggered. This generally leaves at most three other supports that may be linked. If possible, the supports should both increase the number of times Cast On Critical Strike triggers, and increase the effectiveness of the triggered spells. Note that Cast On Critical Strike cannot trigger more than once per frame, so staggered hits (e.g. multiple projectiles) are preferred to simultaneous hits (e.g. most area of effect damage) which will only proc at most once per explosion.
Projectile
By far the most popular family of Cast on Critical Strike setups, projectile Cast On Critical Strike focuses on the projectile keyword. Popular attacks for this purpose include:

Minion
Another possibility is to use attacks to trigger minions, which benefit from attack skills. In addition to the projectile skills listed before, we have some other good choices:
- Module Error: Too many skills found with q_where = skill.active_skill_name="Double Strike". Please choose only one of the following ids:
AxisDoubleStrikeTrigger - N/A (page)

SabreSpiderDaemonCyclone - N/A (page)
SabreSpiderDaemonCycloneRuin - N/A (page): Causes staggered hits rapidly.
Minions generally have poor critical strike capabilities, so critical strike supports are not as effective as they are with projectile spells. Good attack supports include:
- Module Error: No skills found with q_where = skill.active_skill_name="Additional Accuracy": Improves minion accuracy greatly, removes the need for accuracy on gear, and quality gives extra critical strike chance.
- Module Error: No skills found with q_where = skill.active_skill_name="Faster Attacks"
- Module Error: No skills found with q_where = skill.active_skill_name="Melee Splash": While it does not increase procs much due to the splash happening on a single frame, it greatly improves minion effectiveness.
- Module Error: No skills found with q_where = skill.active_skill_name="Multistrike": For Melee attacks.
Most minions are severely capped in number and thus do not benefit much from the high proc rate of Cast On Critical Strike. However, there is one that works well:
- Module Error: Too many skills found with q_where = skill.active_skill_name="Summon Raging Spirit". Please choose only one of the following ids:
SummonRagingSpiritRoyale - Maximum 10 Summoned Raging Spirits, Base duration is 4.00 seconds, Minions deal 20% less Damage, Minions cannot Taunt Enemies (page)
