I am using one now. Pompey the great. he does like 4 x the dmg of blood. he makes baal and cerb easy.
they need to fix this bug.
i used him to kill Lancelot ... to progress to another step.
Now that you have Lance, star him and use him instead of Pompey, his damage sustains while Pompey's decreases. Lance is a much better option for WB.
this is a huge bug and an exploit.
