Frost Nova (Diablo IV)

Frost Nova is a Conjuration Cold spell used by  in Diablo IV, a remake of the classic spell.

In-game
Unlike the classic spell, Frost Nova deals no damage by itself, but instead instantly applies Frozen effect to all nearby enemies (duration increasing with spell rank). It does not apply Chill either, and converts existing Chill effects into Freeze.

Talents:

 * Frostbite (5): Damage against Frozen enemies is increased by 2% per point.
 * Endless Winter (1): Critical strike chance against Frozen enemies is increased by 30%, but Chill effects no longer Freeze.
 * Chill to the Bone (1): Cold damage against Frozen enemies is increased by 30%.

Development
Originally a Conjuration spell, Frost Nova was later moved to Defensive spells, like its counterpart in the third game.
