Corrosive Blade

The Corrosive Blade is a long sword +1, +2 vs opponents with metal armor. The blade appears severely rusted and corroded, but is just as sturdy as any normal sword.

- The Corrosive Blade has additional properties vs metal. Every time the blade hits a metal creature or metal clad opponent, the foe takes an extra 1d6 points of damage.

- Any time the Corrosive Blade hits metal armor or a creature made of metal, the armor must make a saving throw or it permanently erodes 1 point of armor class per round until it disintegrates into a pile of rust at AC 10. Each successive hit accelerates the decay by one cumulative point.  Any metal creature that has its armor class reduced to 10 will be destroyed regardless of hit points.

- If used to parry a metal weapon, the weapon corrodes just like armor.  The affected weapon does half damage for the next two rounds then breaks and disintegrates completely.  Larger than normal melee weapons may take longer.

- It will not affect any magical or enchanted metal, but will still do the +2 to hit, +1D6 damage to metal armored opponents and metal creatures.  It will not affect any metal not used as a weapon or armor, but will still leave small spots of normal rust on the point of contact.
