Sigil Stone (Oblivion)

See also: Sigil Stone (Skyrim)

A Sigil Stone is the object that keeps Oblivion Gates open. They are found at the top of the largest towers in the planes of Oblivion. Once a Sigil Stone is removed, it destroys the Gate it was supporting and transports the player back to Tamriel next to the now-destroyed Gate which now lies in ruins.

Once removed, Sigil Stones are placed in your inventory. They can be used to enchant jewelry, armor, or weapons. They have two separate effects: when placed on jewelry or armor, the item is enchanted with the defensive effect, such as a percent resistance to certain spell types, or other effects such as a percent bonus to Chameleon. When placed on weapons, the item is enchanted with the offensive effect, such as a set damage with certain spells or negative magical effects to the enemy.

Using Sigil Stones are much more profitable than using spells in several ways, and although they give fewer options than all the colleges of magic, they are much more powerful and longer lasting than any possible enchantment. Note that if you repeatedly "take" the stone until you get teleported you may get more than one.

Enchantment Effects
Sigil Stones' enchantments vary in effect and quality. These effects are set when the stone is added to your inventory, and so you can simply save before taking it and reload until you get the desired effect. You can actually activate the stone and save before you get it, making reloading for the desired enchantments much faster. It is also possible to get more than one Stones from one tower by repeatedly pressing the action button as the tower explodes around you; depending on how fast you are, you can end up with several (they are assigned randomly so you could get duplicates), this still works with the latest patch.
