Sludge Hat

A no-rarity cursed Sludge set head armor obtainable from the Trashbags event. Grants +1 Shield but costs -1 Charisma. The head slot piece of the Sludge set, rounding out the trio with Sludge Necklace and Sludge Mask. A marginal defense boost with a consistent social penalty — only worth equipping if CHA is irrelevant to your build and you have no better head armor available.
