Spirits of wind and storm carry your weapon across the battlefield to smite your target, then linger around that foe to hinder its movement.

Encounter   ✦     Primal, Weapon
Standard Action      Ranged 5/10

Target: One creature

Attack: Strength vs. AC

Hit: 5[W] + Strength modifier damage, and the target is slowed until the end of your next turn.
