Glass

Weapons made of Glass are immune to the durability damage from fighting Oozes and Rust Monsters. In addition, they break the DR of some Quori creatures with DR/Crystal, as currently all items listed as material type glass, are essentially also material type crystal.

Weapons made of glass are:
 * Item:Dreampiercer
 * Item:Dreamspitter
 * Item:Muckbane
 * Item:Muck's Doom
 * Item:Shrieking Star
 * Item:Terror used to be made of Glass. As of U18, this is made of "'Gem'", which is NOT ooze resistant. Not yet tested on Rust Monsters.   I have also not tested if "'Gem'" and not "'Glass'" is now required to break DR/Crystal.

A list of items made of Glass can be found on the category page.
