Can someone explain how enchant works?
You find a magic item, say a shield of frost resistance. You break it down, destroying the enchantment, and presumably being left with a normal shield, tbc. Frost resistance is now added to the list of enchantments you understand.
In future, you can use an enchanting altar to put frost resistance on anything, the strength depending on your skill and the size of filled soul gem you have available.
