Josiahfk, did you use meds on THF for Ballistic? Or just ride eva build until you could get TP for waltzes?
Sea daughter gives 30hp/tick and 5tp/tick so if you fight him at max melee range and run away as soon as he readies kick, you'll regen and regain enough hp to continue fighting as you kite him waiting for encumbrance to wear off and tp to build. It's not stylish or fast but it works safely.
I've been more tempted to solo it on war lately than evasion jobs actually lol. If you wait out for arm cannon then fanatics amnesia screen and 2 hour skillchain, it has the potential to one shot him with the skillchain depending on your setup
