Permanent Effects from Quest Items

Permanent Effects from Quest Items

When any quest items (i.e., items that normally cannot be dropped from your inventory) that are equipped are forcibly removed from your inventory, the game removes the item but does not remove the item's magical effects. Therefore, you end up with a permanent magical effect. This effect is truly permanent: there is no way other than Console commands to get rid of it. There may be undesired side effects from having permanent effects.
This will work with any enchanted quest item. Items that are recommended include:

• Ring of the Vipereye
• Draconian Madstone
• Boots of Springheel Jak
• Ayleid Crown of Nenalata
• Ayleid Crown of Lindai
• Necromancer's Amulet
• Bloodworm Helm

The Gray Cowl of Nocturnal can also be exploited in the same manner, but this is not recommended (you will end up with the Gray Fox's bounty and Infamy permanently).
Then complete any of the following, which will force the items to be removed from your inventory:

• Serve time in jail.
• Through a Nightmare, Darkly.
• The Daedric quest of Sanguine.
• Dagon Shrine (as long as you give all of your possessions to Harrow).
• Equip the Ring of Disrobing, a rare item found in the Shivering Isles expansion pack.

When the quest items are later returned, they cannot be equipped ("You cannot equip this enchanted item right now.") or dropped ("You cannot remove Quest items from your inventory."), but their effects remain.
The same bug can occur on the Bands of the Chosen from Paradise if you cast a Bound Gauntlets spell. You will be stuck with the 50% Weakness to Fire and cannot open the sealed door.
The same glitch will occur with any enchanted item if you use one of the duplication glitches. First, duplicate two identical copies of the enchanted item. Equip one, then try to duplicate the non-equipped one. The duplication will forcibly remove the equipped copy of the item, too, and you will be left with the item's enchantment as a permanent effect. This can be done with multiple different enchanted items, as long as each item has a different name.
Using this glitch with Chameleon, Light, Night-Eye, and Detect Life enchantments is not recommended.
