Permanently enchant a melee weapon to often chill the target reducing their movement and attack speed. Has a reduced effect for players above level 60.
Enchanting Level Required: 285
Can apply a frost debuff on a melee hit that causes target's movement slowed by 30% and time between attacks increased by 25% for 5 sec. The weapon enchanted will glow a bright bluish white.
It is unclear if the proc is a PPM (best on a slow weapon) or a chance on hit (best on fast weapon). Switching a weapon enchanted with Icy between main hand and offhand does not seem to affect proc rate. This implies that it cannot proc off of instant attacks (like Battlemaster). The proc rate is significantly less than Fiery.
