I have a questions about what happens when the synthesist eidolon bab gets to +6 or higher. You are supposed to use the eidolon BAB for your BAB when you are fused but when the eidolon levels +6 or higher there is no +6/+1 to the base attack bonus just +6. So when wielding lets say a longsword are you only stuck with the one attack at +6 with it or can you assume you get the second attack at +1 with it like you would if you were not fused?
