Arcane Threshold

When this spell is cast on a doorway, you magically tether yourself to that doorway for one year. For the next year, anytime you cast arcane threshold before stepping through any other doorway, it will be as though you are stepping through the tethered doorway, and you will be transported to the other side of the doorway to which you are tethered. You are able to take up to 4 creatures through the doorway with you.

If you cast this spell on another doorway before the end of one year, it will sever the first tether and establish a new one.

If you cast this spell using a spell slot of 4th level or higher, you can bring an additional 2 creatures for each additional spell level.
