Seidon Steal
Found deep on the ocean floor, in underground caverns, and flooded caves, Seidon Steel is a rare aquatic metal prized by the Merfolk and other sea dwelling peoples. Beneath the waves, it is both lightweight and durable, making it ideal for underwater combat and construction. However, once brought onto land, its nature changes drastically growing heavier, then brittle, unless sustained by water-aligned enchantments.
Properties
Material Characteristics
Seidon Steel is smooth and reflective, its polished surface catching even faint glimmers of light. In the darkness of the sea, it sometimes seems to shimmer faintly, enhancing what little bioluminescence or light sources are present.
Physical & Chemical Properties
While submerged, Seidon Steel remains dense yet lightweight, offering excellent protection without restricting movement.
On land, the metal rapidly changes: its weight triples, and within days it begins losing density. After several weeks it becomes brittle and nearly useless unless bound by a water enchantment.
Seidon Steel strongly amplifies water-aligned enchantments, but it cannot hold fire—any attempt to enchant it with flame will cause it to weaken and shatter.

- Suffers a –1 penalty to attack rolls if used on land without a water enchantment.
Armor
- When worn underwater, Seidon Steel armor has no movement penalties and flows smoothly with swimming motions, particularly for creatures with a swim speed.
- Provides resistance to bludgeoning damage
- Light DR 5/— against blunt weapons
- Medium DR 10/— against blunt weapons
- Heavy DR 15/— against blunt weapons
- On land, armor grows uncomfortably heavy unless enchanted with water, imposing a –2 Armor Check Penalty.
- Seidon Steel arrows and bullets can be fired underwater without penalty.
- Gains +1 additional range increment when fired underwater.
- When Seidon Steel is enchanted with water element, the enchantment gains a +1 value (extra uses, bonus dice, or permanent increase at GM discretion).
- Seidon Steel cannot hold fire enchantments—attempting to do so will render it brittle and destroy the item
Geology & Geography
Seidon Steel veins are found in vast underwater caves or on the ocean floor, often near volcanic vents or deep-sea trenches. Mining it is perilous, as such caves are frequently inhabited by dangerous marine predators or territorial guardians. Larger deposits are typically hidden in expansive caverns, making them both rare and risky to extract.
History & Usage
Manufacturing & Products
The Merfolk were the first to make extensive use of Seidon Steel, forging it into weapons and armor suited to life beneath the sea. It has also been used to construct underwater homes, fortified halls, and even tools and instruments designed to endure aquatic environments. Jewelry made from Seidon Steel is rare but valued among sea-dwellers for its unique sheen.
Hazards
Extracting Seidon Steel exposes miners to predatory sea creatures and territorial leviathans. Magma vents and cave collapses pose additional threats, particularly in deeper deposits.
