This bad decision aside, i’llI’ll explain the puzzle and their situation:
They found a second brazier, that read “Blood of their friends”. There was also a mural that depicted Nemesis sacrificing her best friend while everyone watched. They tried to use the Captain’s blood, and it didn’t work. She suffered some backlash damage (10 points, just to discourage trying to fit anything in the brazier without thinking), and I told her that as far as she knew Nemesis, she had allies and grudges, but only very few Friends and Enemies, as those words were reserved to personal, intimate people. Then they tried with the blood of one of the other players, wichwhich are friends, and it worked.
Instead they activated some Drider traps on purpose to have their blood. When they killed them I explained again how they didn’t leave anything behind when killed, so then they tried to kill one while it was STANDINGstanding on the brazier… wich they accomplished somehow with very lucky dice. It didn’t work either.
