Codex of Shadows

A Codex of Shadows is a rare, endgame special Enchanted Book that contains a single low-leveled Augment. This can be applied to any available weapon or tool at an Anvil, at the cost of a significant number of levels. Up to 3 Codexes may be added to a single item; however, unlike with Enchanted Books, adding two Codexes of the same level will not upgrade the level.

Codex Number	Level Cost
1st	35
2nd	60
3rd	85
4th+	9999 (impossible)

Codex of Shadows can be obtained in the following ways:
