Curses

Curses are an attribute of items that give a negative effect to the item, and make the item unable to be unequiped.

Curses
Every piece of equipment found throughout the game has a chance to be cursed, with some exceptions: Identifying a cursed item will reveal the presence of a curse. Cursed weapons and armor cannot be unequipped by normal means.
 * Items obtained from big chests never appear cursed
 * The Blink Dagger and the Thunder God's Hammer never appear cursed
 * Thrown weapons and unequippable items such as the Grappling Hook and the Pet Whistle can never be cursed at all

If the item has an attribute, it will be twisted to become useless or debilitating.

You can remove a curse by either using a Scroll of Uncurse while the item is equipped, or using a Scroll of Enchant on the cursed item. The latter of the two will not always work.

The presence of a curse can be revealed without identification by offering the item to the Shackled. If the item is cursed, it will become god cursed. Otherwise, nothing will happen.

Curses on Wands are automatically identified.

If a player destroys the Shackled, all items in the current level including items in the player's backpack and items in the shop become cursed.

God Curses
A God Curse restores an item's effect to the normal version and grants the item a large amount of stat bonuses.

A God Cursed item can never be unequipped, unless the character dies in multiplayer.

An unidentified item from the Shopkeeper's Stash is always God Cursed.

Bugs
You are able to swap to another weapon while wearing a godcursed weapons by first equipping a cursed weapon and then using an enchant scroll on the godcursed weapon.

This is probably an unintended consequence of the way enchant scrolls work.

WARNING: Breaking the shackled can sometimes result in items becoming permanently cursed, Scrolls of Uncurse will not work on these items.
