no self-respecting wizard is going to get by on 17 Int. Do Gith still get heavy armor? I might have to try that out.
My last playthrough I gave my Halfling rogue medium armor proficiency and with the shock boots and gith armor I had a pretty good time
I made a Githyanki wizard that doubled as a fighter that was pretty fun. Greatsword proficiency from being a Githyanki, pumped Strength to 15 so that I could take the Heavy Armor feat to make it 16 at level 4. Still had a respectable 16 INT for casting.
Once we get some proper plate it'll make for a VERY tanky wizard who can also hit hard in melee.
