Aggressive [alternate start]
You use Intimidate for the associated skill. You cannot communicate simple concepts or complex information with creatures you share a rapport with. Instead, you can use Intimidate to demand cooperation from any creature who shares your rapport or whose motivation you know as a full-round action without taking a penalty.
Animal Whisperer [alternate start]
You find it much easier to empathize and relate to beasts. You may only use your Communication sphere abilities with creatures of the animal, magical beast, or vermin types, and use Handle Animal in place of the associated skill. You gain the Beast Whisperer talent from this drawback.
