Warp Sense

2nd-level divination (ritual)

Casting Time: 1 action

1 action Range: Self

Self Components: V, S

V, S Duration: Concentration, up to 1 minute

For the duration, you sense the presence of up to two planar portals within 30 feet of you. If there are more than two portals within range, you sense the nearest two. When you detect a portal in this way, you learn whether it is one or two-way, and can use your action and all of your movement to learn either the portal’s destination plane, or the key required to use it, if any. Determining either requires a DC 13 ability check using your spellcasting ability. On a success, you have advantage on your next ability check to learn information about that portal using this spell. On a failure, you cannot use this spell on that portal for 24 hours.

The spell 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.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the maximum number of portals you can sense at any time increases by 1 for each slot level above 2nd. When you use a 6th level slot or higher, the radius of the spell increases out to 90 feet.
