16. The Sword in the Ooze: there is a Gray Ooze lurking here. It appears to be a small boulder, and there is a sword sticking out of it. The ooze will not do anything unless somebody tries to remove the sword, in which case it will attack whoever has the sword. The sword itself is a +1 Longsword, with the ability to burst into flame once per day on command (the command word is written in ancient runes down the blade), dealing extra fire damage. The ooze is related to the black puddings in areas 8 and 9.
Is a +1 Flaming Longsword too much for 4th level? And is a Grey Ooze too weak a challenge to be guarding it?
I'm loving these posts, by the way. Is this dungeon going to be collated into a PDF like the last one?
