I'm curious how the metamagic feat Empower Spell works. Basically, I'm interpreting it 3 different ways and am not sure which, if any, are correct. I'll use burning hands in these examples.
1) Normally 2d4. Increase the variables by half, and it becomes 2d6
2) 2d4=3d4
3) 2d4= roll the dice, and add 50% to each roll.
I feel dumb for asking this, but I cannot find any specific clarification. It seems like it is obvious to everyone except me. Anyone want to help a new DM out?
