I like to use EEKeeper to break a couple rules
My favourite build is taking Storm Cleric + Warrior and RP as a storm paladin, it's really fun every time
i've also run a Warrior + Necromancer with the summoning cap off for fun to march into baldurs gate with a lot of skeletons

I wish Paladin wasn't locked, i think it can be modded to add multi class option to it but it's very scuffed
