Detect Automations

For the duration, you sense the presence of any metal automation or Hephaestus crafted items within 30 feet of you. If you sense any automation in this way, you can use your action to see a faint aura around any visible automation or Hephestus-made object in the area that bears the maker's mark.

The spell can penetrate most barriers, but it is blocked by 3 feet of stone or surrounded by certain types of Divine creations.
