We were able to succeed in Encounter I, though it did get hairy at parts.
In Encounter II we were pinned in by the elementals. Jain ( played by myself ) tried to make a dash for it, but the OL pointed out part of my movement took me illegally through a wall. I then had to backtrack and replay my turn. Eventually we gave up fighting as the situation looked too dire and decided to search everything.
A few of the guards were able to kill one of the flesh molders and we decided we were still in the fight. It came down to the wire.
In the end the heros were able to defeat the OL, but barely. Had we not dealt that last 2 damage it would've been the OL's turn and he would've wiped out the last guard.
