The Elder Scrolls V: Skyrim Game Add-Ons (DLC) Hints

Talk to Talvas.

  • 1 of 5: Reenter the Tel Mithryn tower and float up to the main floor.
  • 2 of 5: Talk to Talvas about the ash guardian to get a random magic staff, and to make him a merchant, a follower, and a master Conjuration trainer. (If he asks if you'd rather learn the Ash Guardian spell or get a staff, choose to get the staff. You can buy the spell from him, and end up with both.)
  • 3 of 5: Ask him what went wrong with the ash guardian spell to learn that you need to have a heart stone in inventory when casting it to prevent it from being hostile to you.
  • 4 of 5: You can buy a spell tome for Conjure Ash Guardian from him, but don't forget to mine some heart stone before casting the spell. (Note that there's a vein of it on the ground behind the Tel Mithryn Kitchen structure. There's even a pickaxe nearby that you can use to mine it.)
  • 5 of 5: Note that ash guardians aren't like regular summoned creatures. They'll stay in the spot where they're summoned and attack all hostiles that come within range until they're destroyed. They won't even disappear if you cast another summoning spell (though note that you can only have one ash guardian at a time).
