rather than beating their head against the wall, if they can complete A Land After Time mission of Rhapsodies of Van'diel, they get access to Escha Zi'Tah and Rhapsody in Umber KI. with that KI they can now use Trusts > yawn through fight since you have a healer and support.
barring that, ye olde Sleeping pot + Opo Opo neck, Sentinel, Invincible, Shield Bash (a good stun can get a Cure off in desperate times), Regen from Pamama or Dragonfruit Au Lait, food, etc are all helpful. gear wise, it has been a long time, so gearing for DD is probably his best bet - Scorpion Harness or Haubergeon, Spike Earrings, etc. AF offers some extra Defense, HP, and magic skills, but Maat is usually a race to the finish, not a battle to outlast. if they can get armor like Sipahi, or maybe Fourth Division armor it might help too.
