Help an Unga Bunga try a magic build.

Since Ds1 I have always been an Unga Bunga. Find me biggest weapon, and bonk endlessly. Can't hurt me if they're dead in a couple of hits. I've dabbled with dex here and there, it's...fine, not my cup of tea, but magic is something I've hardly touched, almost at all in souls games.

Does anyone have tips for an Unga Bunga to learn/play a magic build? How should I allocate my flasks between HP/FP, stat spreads etc.

If it helps, as an Unga Bunga, I've always liked seeing large chunks of damage being ripped off the healthbar at once.

Also madness has always seemed like a super cool theme to me, since i first came across it, I've always wanted to try it but as I understand, it's PVP only and even then it's..mediocre at best.
