Basically a drunken D&D session
Barbarian is a great class for twins. They'll be lifelong allies, even if he kept the axe instead of taking the sword.
I wonder what other classes would work to have twins?
Rogue? Airtight alibi! No, I didn't steal those jewels and a whole Tavern will say I was gambling dice all day!
Cleric? Um, do we really need a 2nd healer?
Wizard? They'll be throwing fireball at each other pretty quickly.
Paladin? I dunno, this seems scary to me.
