Gum

Gums are Centraforge Ingredients that influence what Boons, Quirks, and Defects are added to an Item while Forging.

Gums do not confer a specific Boon, Quirk, or Defect but instead raise the chance of any Boon in a particular category being either chosen or increased. Both Gums and Boons belong to a specific category, which include the following.
 * Ease
 * Lightness
 * Special
 * Effect
 * Longevity
 * Glow

In addition, there are Guns that do not influence which Boon, Quirk, or Defect are selected but instead foxus on expanding or reducing already-selected traits.
