Sacred Haven of Debauchery

Remember those dark screenshots I posted from one of the mods? I found a bow like this in that mod. I'm using it now. It's unclear what enchantment it has; the description only contains some pretentious nonsense (I suspect, however, that it at least drains life), but it hits harder than my regular dragon bow, and it also seems to have an infinite supply of arrows (it summons 250 arrows when equipped). It's unclear whether it will continue to summon arrows when the charge runs out, but it's very effective against enemies.
By the way, I had to work really hard to get this bow. There were two tough enemies with a lot of health, one with this bow and the other with a similarly awesome one-handed weapon. Both of them could one-shot me, so I had to fire about twenty arrows at each of them, and after each shot, I would stealthily run away.
