Acquisition[edit]

In lieu of an icy weapon upgrade, consider using a skill that changes your damage to cold like Grenth's Fingers.
The skill's armor-ignoring damage is added on every hit, including those from skills dealing multiple attacks, scythe attacks, and dual attacks.

The functionality of this skill has changed since its introduction; see its skill history for details.
