Do you mean a Daedric bow? There are all sorts of "destruction and illusion school" enchantments you can put on a bow. Or you can just summon a Daedric bow with the right conjuration spell. That way you never have to repair it. I like to put a Weakness to Fire (or lightning, or frost) enchantment on my bow set to 100% weakness and then use a ranged spell matching the weakness to get a quick kill. Use a black soul gem with a grand sole trapped in it to enchant the bow for the more shots between rechargings). Paralyze enchantments also work well but will not work on vampires. For killing certain monsters (for example, gloom wraiths and daedric monsters if I'm not mistaken) you need a either a daedric bow, a silver bow with any type arrow, or any bow (other than daedric) firing silver arrows. Otherwise only the enchanted part of the arrow/bow will have any affect. All conjured weapons, like the bow, will be daedric and will kill anything. Just as important is your skill level with the bow. At 75 proficiency you have a chance of knocking down the target and at 100 you have a chance of paralyzing the target. Also you get a 3X mutliplier if you are in sneak mode and undetected or under 100% chameleon.
