If Brannor goes out to fight with a sword and shield he'll have an AC high enough to stand his ground against physical attacks, so I nominate him. If we do get a long rest however I'd suggest letting Orchid go out so he can use his rage and reckless endurance, and possibly giving him whatever buffs we can spare. I can hand out Guidance since disarm is a athletics check, not a straight attack roll, so he can get 1d4 on his first attempt.

Ninja Edit: I don't know what Brannor and Orchid can get back from a short rest, but I'm in favor of Brannor.
