TMS fully killed empress in 9 minutes?

Yeah, she heals 840m hp whenever you get her down to 10%ish if you keep crashing her. She'll still summon, sometimes, if you've been crashing. We've tried crashing and trying for summons, which got us to kill 2 instructors, and we tried not crashing and trying for summons, which got us to kill 2 instructors.
