And before you say anything, no I don't want to just be a Monk. I want to be a fighter whose specialty is punching things. No Ki abilities or monastic tradtions or anything like that.
My character for this particular campaign is essentially a retired wrestler based very much on the WWE style of wrestling. She specializes in punches, grapples, and other more close-quarter combat techniques. We have actually pseudo-joked that before she chokeslams people she bellows "Kord! Guide my hand!"
To make this easier for me, the DM has already allowed me to take the Monk's Martial Arts class feature in place of any Fighting Style that I acquire or may acquire in the future, and has allowed me to take the Tavern Brawler feat in lieu of the ability score increases as a human.
My question, however, is what else can I do to focus this character on unarmed combat and wrestling? Especially when it comes to altering the equipment package because… well, all the weapons are pretty useless.
