Ostrine edge

An ostrine edge was a type of melee weapon edge used around the time of the Dark Wars, that had been augmented by the application of a refined form of a rare, heat-absorbing mineral known as ostrine, from the planet Hargeeva. After the edge was added to a melee weapon, it caused the weapon to emit an extreme cold that could damage objects struck by it. This ability also decreased the surrounding temperature, partially protecting the user from extreme heat and fires. Around the year 3,951 BBY, the rare and expensive edge sold for around 28850 credits.

Behind the scenes
The ostrine edge made its first appearance in Obsidian Entertainment's video game Star Wars: Knights of the Old Republic II: The Sith Lords, as a rare, expensive melee weapon upgrade found at random locations throughout the game. Due to the fact that it is rare, the player may not find the item each time through the game. After upgrading a melee weapon with this edge, the melee weapon gave the user a cold damage bonus, and a reduction in damage taken from fire-based attacks. It also gave the weapon an increased chance of a scoring a critical hit, which dealt increased damage. The item had an entry in Knights of the Old Republic II: The Sith Lords: Prima Official Game Guide, by Prima Games.
