Er, I had a hard time deciphering how she was attacking, so I'm just going to have to ask straight up. Was she attacking the Large Body from the front? Because they're kind of completely invulnerable in the front and can only be damaged from behind. Plus... she took that thing down on her own in a single combo? True, Elim hit it with a Blizzard spell beforehand but I know from recent experience that it takes more than that to kill a Large Body at such an early level as this. Hell at this point it might as well be its own little mini boss by sheer force of how much HP they're known to have.
