Embrace true wizardry, being a strung out, barely there weirdo who can do little more than cast spells and say random smart things.

Way I've always seen it is they want, even need, there to be something beyond 'rich fucks keep being short sighted fucks'.

I speak on this since I've had close friends slip into the rabbit hole before getting violently pulled back

Alternatively, a pocket/backpack flamethrower the party can easily smuggle into most cities. After all a guard is a lot less likely to confiscate a splatcat if it looks cute enough(and the guard is sufficiently bribed.)

Always been a big fan of the grottier fantasy's approach to classes. You're either a weirdo or a scumbag, have fun.
