Not a Scratch on Him
Felix ran into the mosh pit and was decloaked again, which at this point is less a setback than a personality trait. The crowd swallowed him, the invisibility did not survive contact, and the band was once more reminded that Felix cannot be hidden, only located.
It took the party an embarrassingly long time to notice the chains coming out of the stage and sucking off Orpheus. In their defense, it was dark and loud. If only the DM had said something — some hint, some flavour text, a single raised eyebrow — but no. They found out the way they find out everything: too late, and mid-combat.
And combat was had. Fireballs were thrown, in the direction of problems and, occasionally, allies. The festival became a firefight. Chains, zombies, the wraith still hanging around from last time — everyone got a turn, most turns hurt.
Felix came out of it completely unscathed. Completely. Not a mark on him. Nobody has asked how, and the DM has not volunteered.
It was, in the end, mostly a fight sesh.
