I've done some research on this and It turns out that any bow under the Demon Bow doesn't have any knockback, and thus cannot have the Unreal prefix as that increases the knockback by a percentage. The Demon Bow and Molten Fury do have knockback, so I assume you can reforge those to Unreal. The best prefixes you can get on all the low-tier bows are Godly, Superior and Murderous.
