Uh oh, since O-chul was not physically destroyed by the blast, Miko may have survived it. Since a lich's paralysis does not toughen up the victim, the blast was not enough to vaporize O-chul {or his corpse if paralysis delays the XX eyes], thus Miko may very well still be alive after she lands.
Well, now we know it's the gate that makes the "BOOM" and not Dorukon's self-destruct button. Guess the OotS didn't listen when their DM told them to hurry...
