Hello, new to 6th edition of Champions, and to forums for that matter. A player has a multi-power with 60 pts. Several of the slots have 15 pts. Their intention is to use both as required, basically combining two attacks into one. The Hero System Combat Handbook, pg 19, says "...a character may not combine two or more slots form a single attack, even if (they have) sufficient reserve or base points to use both slots at once." I do not see a similar restriction in Champions Complete. In first edition there were examples of characters shifting points between blast, flight and force field, but not more than one attack.
