like someone said before, there is a reason why they showed us the monsters dissapearing, but there is a reason why they showed us them being flushed out... if they could just summon the stairs without killing the guardian then the only reason to flush them up would be to get potions and new armors... and that would be lame... and not to say that only fatime and jil were together, maybe each party member is in another floor? but then again they dont have any healer/buffer... that could be a problem
