In Path of Exile 2, the Frostbolt Chronomancer Cast on Crit (CoC) build has become one of the POE 2 Currency most dynamic and powerful setups for endgame content. The synergy between the Frostbolt skill and Chronomancer ascendancy, combined with Cast on Critical Strike (CoC), creates an explosive damage output that can clear maps efficiently and tackle bosses with precision.



Core Mechanics



The heart of the build revolves around triggering powerful spells through critical strikes. Frostbolt, when combined with CoC, releases devastating projectiles that spread cold damage across the screen. The Chronomancer ascendancy, known for its mastery over time manipulation, enhances the build by adding unique bonuses to critical strike chance and damage. This makes it easier to chain powerful cold spells like Ice Nova, Frostbite, or Glacial Cascade when critical hits are scored, ramping up the damage potential exponentially.



One of the major benefits of using a Cast on Crit setup is the ability to scale both your critical strike chance and cold damage, leading to massive burst damage against both mobs and bosses. With the right gear, this build can consistently trigger multiple spells on a single crit, allowing for rapid, screen-clearing bursts of cold damage.



Gear and Passive Tree



To maximize this build, players should focus on increasing critical strike chance, spell damage, cold damage, and cast speed. Key items include Atziri's Foible for more mana and critical strike bonuses, as well as The Vertex or Kongming's Channeled Hilt for boosting your frost spell power. Passive tree choices should prioritize Critical Strike, Spell Damage, and Cold Damage nodes, with key nodes such as Heart of Ice and Divine Guidance offering significant boosts.



Endgame Viability



In the endgame, this build excels in both clear speed and boss-killing potential. With the right combination of gear and passive tree optimization, a Frostbolt CoC Chronomancer can take on endgame bosses like Sirus, The Maven, or the Uber Elder with ease. The build’s high damage output, paired with the Chronomancer's ability to manipulate time, allows players to control the pace of the fight, mitigating incoming damage and staying mobile.



Overall, the Endgame Frostbolt Chronomancer Cast on Crit build is an exciting and potent choice for players seeking to experience PoE 2's high-octane combat while navigating the buy POE 2 Orbs complexities of time-based mechanics.
