Yep. more thoughts on DCC. When I did my little Barbarian class, I had these two in my mind. I blame it on a misspent youth. An idea popped into my little grognard brain to do this without adding an addition class.
So take the Warrior class and drop the Lucky Weapon ability. Instead, at the start of each combat encounter, the character rolls their Deed Die plus their Luck Modifier and applies the result to their AC. Of course, this only works if the character isn’t wearing any armor.
There it is simple and quick.
