Safest Boss Killer - Cold CoC Chronomancer (Budget friendly)

Feb 12: Added 60+ Div setup for Max Diff Full Party Boss Kills.
(Explanation and Damage calculation in Build variants section.)

https://youtu.be/YBdtxA5diOo - Xesht 4 in 7 second on ~40Div setup.

https://youtu.be/3KP8kkvv3Ro - Update on patch 0.1.1c nerf, build is basically same.

DO NOT RUSH WITH GOING FROM LEVELING TO Cast on Critical SETUP! Stay at leveling setup as long as it works. Spec to Cast on Critical around lvl75+, or sooner if you have good gear.

Shortly about build:

• Effortless bossing with Time Freeze that completely stop bosses from doing anything.
• Very good to farm both Trials.
• Good DPS at low budget.
• Clearing is safe but not fast, become better with more investment.
• Fairly tanky with Temporal Chains and Apex of the Moment that make mobs around very slow.
• Become fairly strong at relatively low budget, setup in video costed me ~6Div. At the time (Feb 2025), it cost around 2-3Div.

Forum thread about this build above, with a lot of discussions, different variations and other stuff! For any questions you can either ask in that forum thread, or join my discord and ask me.

How build works:

• When you do Critical Hits with Frostbolt, Eye of Winter or Frost Wall, it builds up energy for Cast on Critical which cast Comets.
  
  
• The way Cast on Critical work:
  - First, Cast on Critical has 10 maximum energy per 0.1 sec of base cast time of skill it trigger. So in this case it's Comet that has 3 sec base cast time, which means Cast on Critical has 300 maximum energy. So once you got 300 energy from doing Critical Hits, it trigger Comet.
  - Then it gain 1 Energy per power of Enemy you hit with Crits.
  Enemy power is static value, Normal mobs have 1 Power, Magic mobs have 2 Power, Rare mobs have 5 Power and Unique have 20 Power.
  - Energy gain also modified by percentage of enemy Ailment Threshold your Critical Hits deal.
  Basically speaking Ailment Threshold - Enemy Max Life, so more damage you have - more energy you get for Cast on Critical.

Clearing options:

• Frostbolt with Snakepit ring. Just spam Frostbolt.
• Frostbolt with or without Snakepit, swap Comet on Cast on Critical with Frost Wall(Keep one you have already).
  So as you hit mobs, it trigger Frost wall, which you also hit and it trigger explosions on Frostbolt.
• Higher budget option when you get more spirit is to use Cast on Freeze with Frost Wall instead of one you cast normally, same supports, Spell Cascade and Inevitable Critical.

Single target:

1. Swap to set 2. Or use Conductivity which automatically swap you to set 2 if you set it only for set 2.
2. When fight about to start use Conductivity, once boss become targetable use Time Freeze and then Soul Offering.
3. Use Eye of Winter, place Frost Walls and hit them with Frostbolt, whatever you will use to hit walls.
4. Hitting Frost Walls will trigger Comet, so once it triggered, it will consume a lot of mana, then quickly after that use Temporal Rift.
5. Repeat 3 and 4 until boss dies.
