Ester’s Detect Curse

For the duration, you sense the presence of magical curses within 30 feet of you. If you sense a curse in this way, you can use your action to see a black flame around any visible creature or object in the area that bears a curse. If you use this action on a curse, you learn of the details of the curse unless the curse is protected from the identify spell or the detect magic spell, in which case you only know that the object or creature is cursed.

The spell can penetrate most barriers, but is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
