Detect Psionics

For the duration, you sense the presence of psionic activity within 30 feet of you. This includes any psionic ability currently in use or imbued upon an item or creature.  If you sense psionics in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears psionic activity, and you learn its school of magic, if any. Furthermore, it will make the user aware of creatures made invisible due to psionics but won't reveal their location.

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