They also ignore the penalty for making ranged attacks within their second range increment against their prey.

Hunter's Flurry [>] Frequency once per round; Effect The slave lord makes two bow Strikes or two melee Strikes, each using a different weapon. These Strikes must target the slave lord's prey. If both Strikes hit, combine their damage for the purpose of resistances and weaknesses.
