I had a disagreement with a friend over what the exact wording on composite blasts mean so I have a clarifying question: Are they intended to do drastically more damage than regular blasts?
E.g.: Which of the two cases is right for a 6th level kineticist casting Blizzard Blast
Case 1: it deals 3d6 bludgeoning/cold damage + spell mod
Case 2: it deals 3d6 bludgeoning + 3d6 cold + spell mod
Composite blasts state that they are generally more powerful than normal blasts, but the intent isn't 100% clear whether that is purely through the utility they offer (as seems the most obvious case to me) or through increased damage as well.
