Protective Whirlwind
Druid Utility 22
Howling wind swirls around you, strong enough to deflect attacks.
Close burst 3
Effect: The burst creates a windy zone that lasts until the end of your next turn. Area attacks and ranged attacks against creatures within the zone take a -4 penalty to the attack rolls against them. In addition, the zone is difficult terrain. When a creature other than you ends it movement within the zone, you can slide that creature 3 squares as a free action.
Sustain minor: The zone persists.
