Waystone

You create a Waystone at your current location. A Waystone is a stone that assists teleportation. Teleportation spells targeting the Waystone have their range increased by 5 times its original. Until the end of the spells duration you may as an action, teleport yourself and up to 7 other creatures to the Waystone. The spell then ends.

Be cautioned, a Waystone can be destroyed by inflicting at least 100 bludgeoning damage (depending on the size and composition of the stone) upon it. The spell ends immediately if the Waystone is destroyed. For the duration of the spell the Waystone can not be moved more than 10 ft from where the spell is cast and can not be moved into a different plane or dimension.

At higher levels. When you cast this spell using a spell slot of 5th level the duration increases to 1 day. At 7th level the duration increases to 1 week. At 9th level the Waystones duration is permanent. When permanent you may, as an action, teleport yourself and up to 7 others to the Waystone once per month without expending a spell slot.
