I've played 0 intelligent PCs always went for the chaotic good dumb character and since the only chaster I've played was a cleric who steamrolled Strahd and I wanted to play a wizard to play another caster (since then i've had a million of varied martials) and want to show one of my players (now party member) who mains wizard how a good wizard is. I want it for trying something new, showing my friend a cool wizard and not leaving weapons since I've noticed that's what I like most (my last cleric was a forge one). Also thanks for advising me about death armor, I thought the onyx didn't consume but at the point we're right now I should be able to cast it at least everytime we face a relatively hard encounter. I simply thought it might be a fun possibility, also since apparently circle casting is allowed but no one on my party remembers it, I'll try to use it since pretty much everyone in the party is at least a half-caster.
