Augmentations, or Augments for short, are mystical stones that can bind with weapons. They provide a benefit to the user, usually damage, while the augmented weapon is equipped. Once bound, the augmentation is permanently fixed to the weapon, but in Knothole Island, there is an Augment Remover Tool to take the augments off of your weapons. However, there are great bonuses to Augments. Some may increase the amount of gold, experience, or even attractiveness. Some of the "cheaper" augments have some drawbacks, such as an exchange of strength to be more easily killed/knocked out.
Most, if not all, augments in a single weapon do not have an increased effect when duplicated.
