CoC: What is CoC in Path of Exile 2?

In Path of Exile 2, CoC stands for Cast on Critical Strike, a powerful support gem that allows players to automatically trigger linked spells whenever they land a critical strike with an attack. This unique mechanic enables fast-paced, high-damage builds that combine attack skills with spells for devastating effects.

How Does CoC Work?

Cast on Critical Strike Support works by linking an attack skill (such as Cyclone or Barrage) with one or more spells (like Ice Nova or Fireball). Whenever the attack skill lands a critical hit^[1], the support gem triggers the linked spells automatically, casting them without the need for manual activation.

To maximize its effectiveness, players focus on increasing both critical strike chance and attack speed. A higher critical strike chance ensures frequent spell casts, while APS must be balanced with CoC’s internal cooldown to avoid missed triggers.

Why Use CoC Builds?

1. High Damage Output:
   CoC builds excel at dealing burst damage by combining rapid attacks with powerful spell effects, making them ideal for clearing large groups of enemies and high-level bosses.
2. Smooth Gameplay:
   Since spells are automatically cast, CoC builds allow for fluid gameplay, letting players focus on movement and positioning rather than manually casting spells.
3. Build Variety:
   CoC supports various combinations of attack and spell skills, offering diverse build options. Popular combinations include Cyclone + Ice Nova and Barrage + Fireball.

What’s New for CoC in Path of Exile 2?

While CoC mechanics are expected to remain similar in Path of Exile 2, the sequel’s improved animations and new weapon options may make CoC builds feel smoother and open up fresh combinations.

Conclusion

CoC in Path of Exile 2 offers an exciting playstyle, combining rapid attacks and automatic spellcasting for high-impact gameplay.
