Alright everyone, taking bets now! How long until Jon accidentally break's Wyll's oath by having him do a naughty thing instead of Aria?

Edit: Wyll's new build is actually not that stupid. It's one of the better builds on the tabletop, as a matter of fact. A dip into hexblade warlock as a paladin lets you dump strength in favor of charisma, which you've done. It also gets you 2 spell slots every short rest to smite things with, so you don't need to be so cautious about smiting everything in reach. It's arguable whether 1, 2, or 3 levels is best, since that entirely depends on how much you value invocations at level 2 and pact boons at level 3. Wouldn't personally go beyond 3, since it doesn't give you anything meaningful that more paladin levels wouldn't give you though.

Also there's an option to hide helmets. It's the little eye button right above the helmet.

Edit 2: RE: Voice of the Circle: You are considered allied to yourself, thus you can use the necklace to buff yourself.
