So in playtest 7, the original version of the Path of the World Tree Barbarian had an interesting capstone ability, and while I didn't think it was necessarily fitting for the subclass I thought it would make a great magic item. So I thought I'd put together a rough draft and see what feedback you all had on such an item. (Also any better ideas for a name!)

Wonderous Item, Legendary

A mysterious crystal orb whose interior seems to be filled with fog, which occasionally breaks to provide glimpses of a variety of locations. Magical symbols are etched in gold around the orb, resembling a teleportation circle.

As an action, the wielder can transport themselves and up to 5 willing creatures to another place, by specifying a location on the same plane of existence. The location can be a city, landmark or other place of note that the wielder is aware of. The creatures will then be transported to the closest Teleportation Circle to the specified location. If the Teleportation Circle is too small to hold all the creatures you transported, they appear in the unoccupied spaces closest to the circle.

Once this effect has been used, it cannot be used again until 1d4 dawns have past. 

 One other thing I was thinking of along with this, would be to make some tables for myself to determine where the players would show up. So a few examples, a Wizard's tower, a research institution, a government facility, but what other places do you think would have a random teleportation circle? A cultist lair? Some ancient ruin?
