Beat Frost Warden by managing chill stacks, holding safe shatter angles, and bursting during crystal break windows.
Fight Overview
Frost Warden is a mobility check. Chill stacks slow your dodge window, so cold resistance and clean lane swaps matter more than raw DPS until the crystal armor breaks.
Pro tip: Never stand near two crystals at once. Shatter cones overlap and wipe greedy players instantly.
Recommended Gear Before Entry
- Armor: Cold resistance chest and boots
- Consumables: Warmth tonic + one cleanse charge
- Ammo: High velocity rounds for crystal weak points
- Utility: Short dash or ice-break grenade

Step-by-Step Phase Strategy
1
Phase 1 - Manage chill stacks
Keep moving on the outer ring. Cleanse at two stacks, never wait for three.
2
Phase 2 - Break the crystals
Focus one crystal at a time from a side angle, then rotate before the shatter cone fires.
3
Phase 3 - Burn the exposed core
After the final crystal breaks, dump rifle into the chest core, then finish with shotgun burst.
Common Mistakes to Avoid
- Ignoring chill stacks until movement is too slow to dodge.
- Breaking multiple crystals together and eating overlapping shatter cones.
- Saving all consumables for enrage instead of using warmth tonic early.
