Curses are an in-game mechanic that either lowers the player's stats or bestows some other negative effect.
There are two different types of curses. 
Major Curses are strong, negative status effects that can not be stacked, and can only be received once per run even after removal. 
Minor Curses are weak, negative status effects that can be stacked. Stacked minor curses will only count as a single curse towards items such as 
Aphotic Charm, 
Twisted Blade, and 
Absolution.
Curses can be Indestructible, but only under special conditions.
