When performed, the user buffs the weapon with Frost; the cast animation takes roughly 2 seconds, after which 65 Frost build-up is added to the weapon for 30 seconds. As soon as the buff is complete, an area-of-effect inflicts substantial Frost build-up on all nearby enemies. This skill requires 15 FP to perform (12 FP if the Farron Ring is equipped).
The skill is effective against enemies that are weak to Frost. At least four consecutive strikes cause frostbite on most enemies.
The Frost build-up can be a useful complement for dealing with players who rely on shields. On top of dead-angling them with the weapon itself, proccing Frostbite on them can deal bonus damage and inflict a penalty to their stamina regeneration, making it harder for them to block attacks and causing them to take more damage if they stop using their shield.
