Be Prepared
We first take stock of our position and find that after the previous skirmishes with the Ogres and undead we have most of our health and, apart from large area-of-effect spells like Fireball and Lightning Bolt, most of our spells to hand. The Paladin decides that we are healthy enough to move on, not needing a rest. Excellent! Onwards.
We pass on from the small dormitory in to a short corridor, at the end of which is an ornate pair of doors, picturing demonic figures in some detail. Opening the doors we are faced with around two-dozen cultists, plus what looks like their leader, all apparently expecting us. We stand our ground in the corridor, hoping they will come to us to make it harder for them to completely surround us, and they do indeed come for us. This groups them nicely together, just right for a Lightning Bolt or Fireball to even the numbers a bit. Ah well, I guess we'll just have to make do with casting a few Create Water spells. That should slow them down.
