> **Casting Time:** Action > **Range:** Self > **Components:** V, S, M (a razorvine leaf) > **Duration:** [[Concentration]], up to 1 minute For the duration, you sense the presence of portals, even inactive ones, within 30 feet of yourself. If you detect a portal in this way, you can take the [[Study]] Action to make a DC 15 ability check using your spellcasting ability. On a successful check, you learn the destination plane of the portal and what portal key it requires, then the spell ends. On a failed check, you learn nothing and can't [[Study]] that portal again using this spell until you cast it again. 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. **Classes:** #Sorcerer, #Warlock, #Wizard
