Due to some bad luck and a couple of bad decisions the entire party is in danger of being killed this week. Four players are currently either dead or dying and the last two guys still standing are rather beaten up. They still have four death knights and lich to defeat. The Death knights have all been worn down to about half their normal hit point total. I have defeated an entire party in the past but their enemies were humanoid and not evil so they simply captured them which allowed them to escape. This time the enemies are evil undead who have no mercy for the living. The two players left standing are tough and resourceful but I think a TPK is very possible. Anyone have any suggestions? They are on a ship near the isle of Orcus so outside help really doesn't make sense. We left everything as a cliffhanger last week because it was six in the morning and the fight still has a ways to go. The characters are all epic level and the players have invested a lot of time and effort nurturing their characters for 22 levels. This is really quite the pickle.
