Nope, you have to use filled soul gems on it.
yes but you have to buy a spell from a spell trader
You use a frenzy spell that you bought or made at one of the spellmaking altars. Or you use the Speechcraft dialogue minigame to reduce how much they like you by boasting, threatening, telling bad jokes etc.
The correct spelling is "oblivion."
There isn't one. There is only weakness to fire, frost, shock, magic, and normal weapons spells in oblivion. There is a weakness to disease spell in Morrowind, i think.
I blew them to oblivion with an atomic bomb; they were blown to oblivion; the Universe was sucked to oblivion; its like they appeared out of oblivion

use a weapon made of silver or druidic
You can buy it at Anvil's Mage Guild.
Join the mage guild, get all the recomendations, enter the university in the imperial city, use the spell making alter.
The Oblivion is made of darkness and light and colored black. Riku is consumed by the darkness, so the Oblivion resembles how Riku is.
