I walking into the last encounter trying to clear a floor only to get ambushed by 5 lvl 45's at lvl 15 and having my entire party KO'd and abandoned on the floor with my highest level back up at lvls 10, 3, 2. Then two of my members got petrified and I had to start the leveling over.

Loving it.

UPDATE: Got everyone back in one piece. If you find grinding gear and levels for 6 people to recover the 4 you lost for going too deep + another during the grind enjoyable, this is a must buy.
