The Elder Scrolls IV: Oblivion/Catalogs/Birthsigns

Birthsign	Features	Notes
Mage	Magicka +50	Spellcaster essential: reliable
Apprentice	Magicka +100, Weakness to Magicka 100%	Spellcaster essential; aggressive.
Warrior	Strength +10, Endurance +10	Perfect fit for fighters; attribute bonuses are always a safe bet.
Thief	Agility +10, Speed +10, Luck +10	Best fit for general stealth gameplay or for a generalist.
Shadow	Invisibility (duration 60) once a day	Useful for problem-solving; extremely potent for thief and assassin quests; useful often and at all levels.
Lover	Paralyze (touch, duration 10) and lose 120 points of Fatigue once a day	Useful for problem-solving; potent; useful often and at all levels.
Ritual	Restore Health (magnitude 200, instant) once a day, Turn Undead (magnitude 100, duration 30)	Useful for problem-solving; potent; useful often and at all levels.
Tower	Open Average Lock once a day, Reflect Damage (magnitude 5; duration 120)	Useful for problem-solving; potent, but passive and subtle; useful often and at all levels.
Serpent	Four effects, all at once, once a day--Damage Health (touch, magnitude 3, duration 20), Dispel (magnitude 90), Cure Poison, Damage Fatigue (self, magnitude 100)	Useful for problem-solving; weak; rarely useful, but at all levels.
Atronach	Magicka +150, Spell Absorption 50%, no Magicka regeneration	Spellcaster essential; dicey; restoring Magicka is a time sucking chore.
Lady	Willpower +10, Endurance +10	Attribute bonuses are always a safe bet, but less useful than Warrior unless your character concept mixes many Willpower and Endurance-based skills.
Steed	Speed +20	Attribute bonuses are always a safe bet, but Speed only governs Acrobatics, Athletics, and Light Armor, and only Light Armor is useful.
Lord	Restore Health (duration 15, magnitude 6), Weakness to Fire 25% all the time	Heal spell is powerful at low levels, remains useful into high levels, but comes with a permanent weakness. Useful for character concept without Restoration.
