Howling Winds

You create a constant blast of bitter wind, emanating from you, blasting snow in the face of enemies, and making it difficult to see or hear.

At-will, std, emanation 2+1/rank, concentration, 1 Vitae; you and allies gain partial concealment to enemies adjacent within 2 squares, and total concealment to enemies further away.

Enemies must pass a Str save to move toward you; on success, they can move at half speed, and on failure, they make no progress. Small or flying creatures have disadvantage on this save.

The cold is bitter, but not enough to cause frost damage directly. However, at rank 2, the cold increases. Enemies suffer light damage at the start of their turn while in the area, plus chilled (Con ends). At rank 3, the damage increases to medium, plus rooted (Con ends, replaced with chilled, Con ends).
