Hi Mark, I have a question about Barbarian's rage power unexpected strike.
Unexpected Strike (Ex): The barbarian can make an attack of opportunity against a foe that moves into any square threatened by the barbarian, regardless of whether or not that movement would normally provoke an attack of opportunity. This power can only be used once per rage. A barbarian must be at least 8th level before selecting this power.
If your enemy use 5 ft step to move into your threatened square,will this rage power grant you an AoO?
