Can I use multiple enchantments?
When I destroy something in the enchantment table that has multiple enchantments, can I then enchant another item with those enchantments at the same time?
To enchant an item with multiple enchantments, you must have the extra effect perk. This allows you to enchant an item with two different enchantments. Some enchantments have two parts, see here for a list of enchantments, however disenchanting an item with two different enchantments will not allow you to add both enchantments as one enchantment to another item.
