The altar from biome makeover can enchant items 1 level past there normal level, such as getting sharpness VI. This is balanced by getting a random curse which cannot be removed even in a grindstone and making cursed items unable to go through the process again, however the curse can be removed with a dark enchantment table.

I propose that the dark enchantment table not be able to remove curses, as it makes curses meaningless and this possible
