PC: Logan, Level 2 unchained rogue
Adventure: There is no Honor
Location: Underneath Parrot Island
Catalyst: Total zombie overload
The party took their ambush by Vanthus in their stride and set about exploring the dungeon confidently. Maybe with too much confidence as a series of unfortunate events took place in each room they entered. They accidentally break the dungeon's power source which is pumping the water out. They get mauled by crabs. They slip over in a slippery corridor and get covered in gunk. This was an extended skills challenge to determine how many zombies they would face in the final room. As they failed to the maximum possible extent, they would be facing 12 zombies plus Kyd the huecuva. Yikes!
The d20 encounter calculator predicted that the battle would be 'overpowering'. I thought it was a likely TPK. Fortunately the party had a cleric present and had encountered Kyd in an earlier battle so they at least knew what they were up against. They planned well, took out the BBEG first then turtled to let the cleric channel round after round, but the rogue fell in round 7 just as the cleric was finishing off the last of the undead.
The party plan to use all the treasure they final in the dungeon to get him raised. I encouraged them to spend the cash on equipment and let the player roll up a new character - I think they are going to need all the help they can get - but they want to do 'the right thing'. :D
