    Cast On Critical Strike Support

    CastOnCritCast On Critical Strike Support (commonly referred to as CoC) is a Support gem that causes linked Spell to trigger when the player scores a critical strike with the Attack skill it is linked to.

    Skill functions and interactions

    • There is an internal cooldown to how fast spells can be triggered, as of patch 3.5 the cooldown is 150ms, or roughly 6 casts per second given optimal conditions.

    • In case of multiple spells linked to one attack skill this support will alternate the spell being triggered.

    • Trigger order: Trigger gems and their linked skills are cast in a certain order that depends both on which item it is equipped on and which socket the skills are in. If there are trigger gems in each equipped item, the order of operation will be:

      • Main hand ⇒ Amulet ⇒ Helmet ⇒ Off hand ⇒ Body armour ⇒ Gloves ⇒ Boots

    • The linked sockets also follow a specific order, as follows:
    1 ⇒ 2
    4 ⇐ 3
    5 ⇒ 6
    • Cooldown Time: When a supported spell is successfully cast, it and all supported spells of the same name are put on cooldown for 150 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 150 millisecond cooldown time as long as they are different.
