Sulphuric Poisoning

Sulphuric Poisoning is a debuff caused by being submerged in water in the Sulphurous Sea biome, or inflicted by the Sea's Searing and Scourge of the Seas's stealth strike. It is also inflicted by many of the weapons dropped by the Old Duke.

The debuff is removed as soon as the player exits sulphuric water. Sulphurskin Potions and Sulphurous armor will reduce the damage taken from this debuff. The Effigy of Decay, Aquatic Scourge's lore item, and Silva armor will make the player immune to this debuff.
