Patch Changes
November 29, 2022
  • This skill now grants additional duration to Cooling Vapor and Frost Aura when used above 100% heat, in addition to its previous effects.
October 04, 2022
  • Increased base healing from 4,740 to 5,250 in PvP and WvW.
October 26, 2021
  • Multiplicative damage reduction enhancements have been updated to display how much damage was reduced by rather than displaying how much the damage is multiplied by. For example, protection now displays "-33% Damage" instead of "67% damage." This is not a change to functionality; it is only a change to display the bonus in a more intuitively understandable way.
October 05, 2021
  • All effects that provide a percentage reduction to incoming damage have been standardized to stack multiplicatively.
February 25, 2020 Competitive content update:
  • (Competitive split) Increased cooldown from 20 seconds to 25 seconds.
November 07, 2017
  • This skill is now a blast finisher.
  • Chill duration increased from 2 seconds to 4 seconds.
September 28, 2017
  • Fixed an issue that caused the heated version of this skill to sometimes heal for different amounts on each pulse.
  • Fixed an issue that caused this skill to pulse chill to nearby foes after the initial chill burst.
September 22, 2017 Path of Fire release:
  • Coolant Blast has been added to the game.
