Multiple Attacks in 1 Round

There are some combat skills, talents, capabilities or situations that will allow characters to declare and make multiple attack rolls in a single round. When this happens, the primary attack roll is made at the character’s initiative point, and any remaining attack rolls are made at the end of the round. In making multiple attacks, once the first of the attacks is made, the character may no longer cancel his action to perform other actions as described in Canceling An Action though he may still cancel his remaining attacks.
