Don't remember the details now, but if I had to guess, it had something to do with Otoha's AS abilities - her primary Attack Move grows it's power output and crit chance/damage with each turn. Plus, IIRC, the boss has periodical opportunity windows where it's possible to attack it (maybe through applying necessary debuffs, but I'm not sure). After several misses/absorptions the accumulated values were really large, plus the absorption was lifted at the moment, which resulted in that huge amount of damage. Probably not possible with the free Team setups, but who knows, grastas are forever.)
how are you doing damage to crab bonze?
