Tumna moves further into the room and blasts energy at the creature with her mind. But when she searches for a mind in the space that the creature occupies, she finds nowhere to direct the energy. The space is empty, as though the creature weren't even there, and the energy dissipates without effect. (The creature is Immune to mind-affecting abilities)
Richard's bastard sword easily makes contact with the creature. The blade cuts easily through the armor of fungus and mushroom caps covering its torso, but meets some kind of resistance where Richard guesses the creature's skin should be. Pulling the blade away, Richard sees that the creature's blood runs as black as the pus in the mushroom caps above ground, and to his horror, the long slice in the creature's torso instantly begins to heal. The creature, which, Richard is now undoubtedly sure, is not a gnome, makes no reaction whatsoever to the pain of the cut. (Damage reduction ?/?)
Khairi (NPC'd) catching on to Rinya's thought that this may be an ambush, moves up to watch the north west tunnel. He prepares for trouble (ready an attack against anything that comes his way).
Thallirae, caught in the silent effect, opens her mouth to say something and then curses (silently). She dashes right, to accompany Rinya in the roots. (couldn't get in position /and/ ready an attack, so double move)
[sblock=Rinya: ]Thallirae says, "Richard is blocking the way, I cannot reach the gnome. I hope you are not correct in thinking this is an ambush..." Her words trail off as you both hear what sounds like galloping coming from the tunnel in front of you, thudding against the soft padding of the mushroom root floor. Approximately six horse legs are approaching, fast.[/sblock]
Suddenly, new opponents enter the fray. From the south east tunnel, guarded by Rinya and Thallirae, a medium-sized humanoid emerges. From the torso up, he is barechested and looks like a male elf. From the waist down, he has two legs that strongly resemble a goat's. Two black horns jut out from his forehead. On his scalp, instead of hair, he has black and purple mushroom caps, from which extend long roots like locks of hair.
[sblock=Knowledge: Nature DC 10]This new friend is a satyr, a type of fey.[sblock=Knowledge: Nature DC 15]Satyrs are resistant to damage except from weapons made of cold-iron. They sometimes have magical pipes that can charm humanoids, but this one has none.[sblock=Knowledge: Nature DC 20]The fungus growing on both of these creatures is granting them some special qualities. You suspect wound regeneration is one of them.[sblock=Knowledge: Nature DC 25]Beneath the layers of black fungus on the "tentacle gnome", you recognize the now-familiar shape and size of a nixie, the water fey you encountered earlier. This nixie's body has been entirely consumed by what looks to be a parasitic, mobile fungus.[/sblock][/sblock][/sblock][/sblock]
The first goatman charges right up to Rinya, intending to head butt her with his horns, but Rinya was ready for just this. (Rinya, please take your readied standard action.)
