Shader Grabbags

Shader Grabbags are items added by Immersive Engineering. When right-clicked, it will be consumed to produce a Shader of its Level; for example, a Common Shader Grabbag could yield an "Argo" Shader.

Loot
Shaders can be obtained as loot in the world:
 * Through the Engineer Villager.
 * Through the Engineer's House.
 * Through dropping from bosses.

Recipes
Shader Grab Bags can be downgraded from higher level Shader Grab Bags or Shaders.

Trivia

 * The Relic Shader Grab Bag cannot produce anything, since there are no Relic Shaders. It can be converted to an Epic Shader, though.
 * The Cosmic Shader Grab Bag will only yield a "Cosmic" Shader.
