I disliked the Vanilla Oblivion Vampirism, and I tried the other mods but they didn't have enough progression for me, they only had a few levels of age. so I made this mod.

Fix:
Due to comments, I have added another fail-safe to the Aging script, it should all work properly now, even under extenuating circumstances.
Version 2:
I've made the Vanilla Vampirism change into this mod's upon load.
I've halved the Fire Shield per level of Blood of Fire.
I've changed the Detect Life into a toggle.
Version 1.6:
I've fixed the bug that prevented the player from becoming a vampire, also
a few minor bug changes.
Version 1.5:
I've doubled the amount of Vampirism you have at each level of age, so that you look fully vampiric when you first turn. I've also added Water Breathing starting at level 22, which I forgot to do before.

There are 61 levels of age, so you will always be getting more powerful.
I've made 10 levels of starvation/Blood Hunger, starting at the sixth you start to lose health.
The Vampire Hunter's Sight is toggle-able.
There are 12 Lesser Powers that you can get as you age or drink more blood:
Vampiric Charm - Charm on touch
Vampiric Allure - AoE Charm on target
Minor Embrace of Shadows - Chameleon
Embrace of Shadows - Chameleon
Terrorize - AoE Demoralize on target
Vampiric Flame Touch - Burns an enemy for 30 seconds, burns you for 10
Vampire's Flaming Hands - Burns for 2X as much as Flame Touch, same timing
Vampire's Infernal Grip - Burns for 3X as much as Flame Touch, same timing
Vampiric Fire Dart - Identical to Flame Touch, except hits on Target
Vampiric Fire Bolt - Identical to Flaming Hands, except hits on Target
Vampiric Fire Ball - Identical to Infernal Grip except hits 15ft area on Target
Vampiric Fireblast - Hits 25ft area dealing 40dmg/second for 30seconds, also deals 40dmg/second to you for 10 seconds.
Greater Powers:
Shadow Form - Gives you 95% Chameleon for 120 seconds, also adds 6 Sun Damage and 100% Weakness to Fire
Vampiric Seduction - 100 Charm on touch for 120 seconds
Reign of Terror - Demoralizes and Silences 30ft area for 30 seconds
Vampiric Infernal Soul Wave (Age 61) - Demoralize, Disintegrate Weapon and Armor, Fire Damage 50/second, and Soul Trap on a 50ft area for 60 seconds, also deals 50dmg a second to caster for 20 seconds.

You get varying levels of Blood of Fire as you drink more blood, these increase your luck, your fire resistance, and give you fire shield. At higher levels they also give fortify Fatigue and Health. After you drink enough blood you gain a Master level Conjuration that allows you to conjure a Vial of Blood, you can only cast this if you don't have Blood Hunger.
