PCs: Human Cleric, Halfling Rogue, Goblin Monk, Goblin Sorcerer
Overall: one PC knocked down to 0 HP twice, but no PC deaths, all goals accomplished, didn't fight the centipedes or the quasits
The real stars of this one were the Human Cleric, who was optimized for healing, and the Goblin Monk. I was surprised at how effective the Monk was! Especially with the Cleric backing him up. The Monk went down twice to Drakus (two critical hits!), but the Cleric got him back up again (and the Monk spent a Hero point the first time). He had Tiger Stance to do slashing against Drakus, which was also good.
The Rogue got to sneak around, disarm the statue trap, and find the secret door, so she had fun. She also got a wicked sneak attack off against Drakus.
The Sorcerer had substantially less to do, in part because he cast summon monster too early (in the first goblin room, with only one goblin left standing), and then didn't have it for later fights where it would have been useful. They did get to avoid the fungus, however, by sending in the summoned monster to check out the room.
My dice luck is legendarily bad, which is to say, I rolled a lot of 1s and 4s, but then I did crit twice in the last fight :) However, the goblin fight in the back cave was also a lot of fun to run, the party felt pretty challenged by the adventure as a whole.
