My main is always Sorceress, it was my first playthrough. I chose Wild Magic, which is both hilarious and frustrating.

Second was a Wizard Necromancer. The Necromancer was more planning and strategy, which I like. Planning out where to get corpses (maybe leaving some for later) and when to long rest so I didn't waste any good corpses. Honestly really fun! Much stronger necromancy spells than if you do not specialize in Necromacy, so viable for strong fights. I took down Orin one-on-one (or one-on-one + undead friends) with that build.
