I have a magic staff that has an enchant that summons a familiar for 60 seconds wherever the caster is pointing but when I go to the arcane enchanter table, it does not show for for disenchanting. Are there certain things you can disenchant or do I need to be certain level in enchanting to disenchant these items?
You may neither enchant nor disenchant staves.
Additionally, you may not disenchant unless the item has an enchamtment you don't already know.
Additionally, there are some quest rewards you may not disenchant (for example: Ghost Sword).
And finally, there are some items (such as the Amulet of [Insert Aedra here]) that you simply can't disenchant.
