Discern Travel

Your sight shifts and recent disturbances in reality caused by inter-planar travel become visible to you. 

If the travel spell is of 3rd level or lower, you are able to determine which spell was cast. If the spell was 4th level or higher, you will have to make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, you are able to identify the spell as normal. 

If this spell allowed movement of 500 feet or less, you can make an Intelligence (Arcana) check to determine the direction of travel. 

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you are able to identify travel spells if its level is less than or equal to the level of the spell used.
