Sulfopatinate Alloy[edit]

Deep in the Para-Elemental Plane of Ooze, the home of the deity Ghaunadaur known as the Cauldron of Slime sits, bubbling with all sorts of oozes and dangerous primitive creatures. This dangerous chaotic evil deity had acquired many enemies who would smite it from existence, but it was held up protected by its corrosive kin. In response their enemies forged a material out of strange alchemical processes, submerging base metals within a strange chemical bath for a long time and forging it into shape within the chemical brew and devoid of oxygen. The result was a new material born of sulfur and steel, and able to manipulate other chemical processes known as sulfopatinate alloy. Sulfopatinate Alloy appears to be a rough pockmarked gray metal when polished and cleaned, but it is usually coated in a dull yellow and thick patina which adds considerable heft to the item. Its body is porous to several acids, which it converts into patina which then returns back to dangerous acid when the patina is broken from physical impacts. Care must to taken to keep acid away from freshly polished sulfopatinate alloy, lest a patina forms and makes forging difficult, melting away the very tools that work upon it.

Any weapon primarily composed of metal can be made as an sulfopatinate alloy weapon. Sulfopatinate alloy weapons count as cold iron weapons for the purposes of bypassing damage reduction. It doubles the weight of items, but is able to store acid potential within it. If the weapon is exposed to acid damage (including if you are struck by an acid attack) it stores the acid damage within it, up to 100 points of acid damage. Each hit with an sulfopatinate alloy weapon deals up to 5 points of acid damage on each attack until its reserve of stored acid is depleted. Weapons made of sulfopatinate alloy gain a 10% discount on any enhancements which deal acid damage.

Armor and shields can also be made with sulfopatinate alloy. Armor and shields have their weight doubled, their Max Dex reduced by 1 (minimum 0), and their armor check penalty increased by +50%. Such armor or shields provides energy hindrance acid based on the type of armor or shield. Bucklers, light shields, and light armor have hinder 10%. Heavy shields and medium armor have hinder 25%. And tower shields and heavy armor have hinder 50%. Hindrance overlaps, it does not stack. Armor and shields made of sulfopatinate alloy gain a 10% discount on any enhancements which grant acid resistance.

Sulfopatinate alloy is so costly that weapons and armor made from it are always of masterwork quality; the masterwork cost is included in the prices given below. Thus, sulfopatinate alloy weapons and ammunition have a +1 enhancement bonus on attack rolls, though the armor check penalty of sulfopatinate alloy armor and shields actually increase.

Sulfopatinate alloy has 15 hit points per inch of thickness and hardness 10. Against acid its hardness is 100, making it almost impossible to damage with acid.

Type of Sulfopatinate Alloy Item Item Cost Modifier
Ammunition +160 gp
Light armor, bucklers, or light shields +1,000 gp
Medium armor or heavy shields +4,000 gp
Heavy armor or tower shields +9,000 gp
Weapon +8,000 gp
