So, playing around with the skillcalc...

I've considered creating a variant using Death Blossom and Explosive Blast as primary attack skills. It should be fun. But understand that what you are creating is a variant. If this is your first time playing a Wizard, I think you'll be very disappointed with the way Death Blossom works. I don't want to discourage you too much, as I think there's a place for a variety of skills, but you might want to play a Wizard a bit and mess around with the skills to see how they actually work in game.
