A set with high overall Elemental Defenses, and Poison Resistances, but with bad Physical Defenses.
The Madman Garb is the most bizarre part of this set, not only are there strange bluish tentacles or perhaps parasites around the garb, there is also a noose and two glass flasks hanging from the neck.
Upon closer inspection, the noose is somewhat glitched as the rope that dangles usually pops out from the knot itself.
The Madman Set is worn by the Tomb Prospectors who went mad. This is why the Forgotten Madman attacks the player with Healing Church weaponry.
