Deep Freeze is a mage ability learned at level 66 for those with the frost specialization. It causes a target to be considered Frozen for the duration of its stun, turning it into yet another tool for mages to perform [Shatter] combos with.

Spell frost frostbolt02 Frost specialization ability


This spell is best used at the very end of a [Frost Nova] to maximize the opponent's Shatter-able and stationary time and minimize the risk of them trinketing the effect right away. It can be somewhat reliably used as an interrupt when coupled with [Fingers of Frost].

Note, however that this spell is not off the GCD. It is subject to diminishing returns in the controlled stun category (such as Cheap Shot); [Frost Nova] will not diminish the results of Deep Freeze.
