Warp Sense

You touch yourself or one willing creature and imbue them with the ability to sense the presence of portals or planar gates within 60 feet. The affected creature cannot move while this spell is affecting them, or the spell ends. Once the creature detects a portal, the creature affected by this can make a DC 15 Arcana check to deduce where the portal leads to or what form the portal's key takes. If the creature has seen the portal in operation, they make these Arcana checks with advantage. Each piece of information requires a separate check, and if either are failed, no more information about the portal can be gleaned during this casting of the spell.
