My level 85 Ysh'tola (full LB, 5* awaken) has 966 HP, 51 AGI (job levels 14/10/10)
My level 51 Ayaka (LB2, 4* awaken) has 1277 HP, 52 AGI (job levels 9/8/8)
Ysh'tola is garbage, man. Better to just go with no healer because if it's that dangerous of a fight Ysh is probably just gonna die anyway lol
