Scarstone

An extremely rare material with several dangerous qualities. Even when it seems perfectly smooth, brushing your fingers across such a surface will leave tiny tears in your flesh that seem to struggle to close again. Indeed, a wound caused by Scarstone will permanently leave scars that cannot be healed or even lessened by any means. This material is pitch black with deep red streaks through it.

When attacking a target with a melee weapon or ammunition made from Scarstone, the target suffers Bleed damage for 1d4 rounds equivalent to 1 + 1 per size category above tiny (eg, a medium weapon would do 3 Bleed damage)

Scarstone can also be used in making armour and shields. In these cases, unarmed or natural attackers take 1d4+1 bleed damage per successful attack.

Handling any item made of Scarstone is dangerous; failing to take appropriate safety measures, such as properly sheathing a sword or covering the Scarstone elements of a shield with a thick sheet, inflicts 1 bleed damage to the handler.

Naturally, this does not impact creatures that cannot bleed such as constructs.

A Scarstone weapon weighs approximately 1.5 times the weight of a standard weapon (10lbs becoming 15lbs) and costs 5,000gp per pound (after weight calculations)

Scarstone has 10 HP/inch and a hardness of 10.

Additionally, many countries have outlawed Scarstone as an overly dangerous material, and players wielding such a weapon may find themselves on the wrong side of the law.
