Hey Everyone, I've spent the last week trying to find a weapon with the Banish enchantment on it. After trying the solitude shop over and over it never turned up. I waited about 3 months game time in Fletcher's, rechecking every 48 hours and he never had the bow. However, I did finally find it. Not once but twice. I found both of them in the Thieves Guild both within 15 minutes. Tonila had the bow of Expelling which is pretty much the same thing. lvl 20 deadra sent back to Obilvion. Then I found the ebony bow of Banishing located in the back part of the The Ragged Flagon-Cistern. You'll pass an Alchemy lab on your left. It's located in a "master" lock chest. It's in the room where the bow/arrow targets are set up and in that room there are 5 different chest with different skill level locks. Again I found it in the "Master" chest. My character is lvl 40. This is the second time I've unlocked these chests. The first time was when I first joined the guild and I was a much lower level character. So if you have already been there, check again. Hope this helps in your quests. Happy Hunting!
