Blueshine

Blueshine is a material with which some armor and weapons are made out of. The special properties of Blueshine are that it will never take damage from acid or rust, making it particularly useful when fighting things like Oozes or Rust Monsters as these creature can degrade your equipment rapidly. It is important to note that the text "Blueshine" will not be included in a weapons name found with this property. Instead the weapons suffix properties will contain the text "Everbright" which will also give it an additional property as well as changing the weapon's material to Blueshine. The in-game description for these items follows:

Armor: This armor glistens with a blue-black sheen as if it were covered with an oily liquid sapphire. A suit of armor imbued with this property never tarnishes and is immune to acid damage and rusting effects. While wearing blueshine armor you gain a +3 competence bonus on Hide checks.

Weapons: Flecks of marble and pearl shimmer across this weapon, set within images of bursting stars and beaming suns. An Everbright weapon will never take damage from acid or rust and can emit a Blinding Flash 3/rest.
