Blights are detrimental passive items, like a negative version of relics. They appear in Endless Mode. They are forced onto the player by Neow each time they defeat Act 3 bosses, and from blight chests, if the Blight Chests mod is on.

Neow's Blights[]

Each time the player defeats the Act 3 boss and loops back to Act 1, they obtain a set of blights from Neow. The following is a list of blights that can be obtained from Neow.
