Obviously, my concerns are in Madness difficulty. The first wave is insanity: 3 magus Soulless Demons with Avenger and Power talismans, and 2 Angels of Mercy with Destiny talismans. It results in an orgy of revenges and shields that need to be stopped with block beneficial effects or perfect corruption and remove beneficial effects.
The next waves are not anything beyond what's normal until the boss fight. You can't use damage buffs due to the Madam's passive (forget about Primordial talismans or warrior Lilith) and because of their talisman choices, you have to remove their buffs to have any options.
I've managed to get through the dungeon with the following roster (talisman sets in parenthesis):
Alexander Eddie (Valor)
The Clairvoyant (Destiny, Shell)
Val, Valkyrie Guardian (Energy, Thief)
Golden Pharaoh Dog (Energy, Thief)
Now, to clear an event achievement, you got to get through it only with assassins. I haven't find any roster that passes through the first wave. Iron Eddie works well, but Set with Eclipse was beaten out in two turns, and Astra Valkyrie Slayer's power skill didn't block buffs. Has anyone found any team that works or has more suggestions? (I don't have Beast Eddie, by the way)
