For effect I had changed the ritual slightly so the drums were beaten and the chimes rung and the triangle struck to start the ritual, it then became translucent and the players had 3 rounds to save the sacrifice. Foddy ended up fighting Eclavdra next to the altar at the point the eye appeared and the tentacle grabbed the nearest living creature - which happened to be Eclavdra. As she was grabbed she attempted to grab hold of Foddy to save herself and I ruled that on a roll of 20 she'd grab hold of him.
Foddy is drawn into the altar along with Eclavdra. Silence at the table.
I left it for about 30 seconds before one of them remembered they had a ring of three wishes (from G3) with one wish left...
