A Madness Cuirass can be forged from madness ore by the smith Cutter, who operates Cutter's Weapons in Crucible. She can forge one cuirass from five pieces of madness ore. Providing a Madness Cuirass Matrix will cause the shield to be enchanted, as well. The quality of the cuirass and, if applicable, its enchantment is scaled to the Hero's level at the time when asking Cutter to make it.
