The Purifier

Curses can be annoying and can sometimes render items completely useless. Sometimes you find a great armor piece in a chest or other loot source, but it comes with a costly curse. To help with this, I propose the purifier. The purifier is a block like an enchantment table and grindstone, but focuses on removing curses. The cost for removing curses would be exp levels, and increase in price the more valuable an item is. The crafting can be whatever you like, maybe try to make it involve a resource from the nether. Also, to balance things out, maybe add a new curse. Something like "Curse of inaccuracy" For bows and crossbows.
