Today, the GM, using a full attack, did the following... attacked one character, took a 5-foot step, and then continued the attack on two other characters. The enemy was a monk, and as far as I remember, there’s a special feat that allows for this, but the GM said no... however, they couldn’t find a rule that says so. So the question is… could they do this without a feat? Attack, take a 5-foot step, and then continue their attack?"
