This question already has an answer here:
My group and I are new to D&D and we read through the rules for the D&D Next play test. It seems to indicate that attack modifiers apply to damage as a bonus. Does this apply with the magic modifier to spell damage? So does 18 intelligence for a level 1 Wizard give +5 bonus damage to spells? I don't see how the attack bonus otherwise would be relevant since it seems the opposing creatures have to make a DC check against the spells.
Am I missing anything?
