Tag Along

You attempt to tag along to a teleportation spell. If the spell is of 4th-level or lower, you are teleported along with the intended targets. If the spell is of 5th-level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, you are teleported along with the intended targets. You appear next to the targets in the nearest unoccupied space. When the spell ends, you may return to your original position and plane of existence.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you tag along on a teleportation spell if its level is less than or equal to the level of the spell slot you used.
