If you want a cake walk, then open hand monk with a tavern brawler feat demolishes everything. High DEX, high WIS, dump STR and find a way to increase it later with an item or a potion of hill giants str. Kill everything.
If you want more of a balanced experience, then go bard. Choice of spells would be the trickiest part, but I believe you'll figure it out. If you take a bad spell, game allows you to replace one spell with another each time you level.
