24 points of Base Damage, Drain Speed 30 points for 45 seconds, Fire Damage 35 points. Leveled weapon, maxed out stats at level 19. 59 points of Total Damage (Note: this number does not include damage done with equipped arrows).
Hatred's Soul Bow - bow, vanilla Oblivion. 70 points Shock Damage, 10 points Damage Strength. Leveled weapon, maxed out stats at level 25. Staff of Indarys - staff, vanilla Oblivion. If he doesn't have it equipped then I guess it's possible and probably one of the better things to get early in the game. If he's got it equipped then it's impossible to pickpocket from him. Note: I'm not even sure you can get this staff because it's carried by Chancellor Ocato. 80 points Total Damage Staff of the Battlemage - staff, vanilla Oblivion. Either Fire, Frost or Shock Damage 80 points (enchantment chosen by player during the course of the Mage's Guild quest line). Leveled weapon, maxed out stats at level 15. 99 points Total damage Mage's Staff of Destruction - staff, vanilla Oblivion. 33 points Fire Damage, 33 Frost Damage, 33 Points Shock Damage. Note: when I say 'total damage' I'm referring to total health damage. My hope is that this thread will semi-regularly get bumped. Okay, I think it's time to make a definitive thread that lists, in order, the most damage dealing weapons in the game.
