Wondrous Item, legendary
This fine black cloth, soft as silk, is folded up to the dimensions of a handkerchief. It unfolds into a circular sheet 6 feet in diameter.
You can take a Magic action to unfold the Well of Many Worlds and place it on a solid surface, whereupon it forms a two-way, 6-foot-diameter, circular portal to another world or plane of existence. Each time the item opens a portal, the DM decides where it leads. The portal remains open until a creature within 5 feet of it takes a Magic action to close it by taking hold of the edges of the cloth and folding it up.
Once the Well of Many Worlds has opened a portal, it can’t do so again for 1d8 hours.
Guys I think this is just a good dm plot thing not useful for players to own
Is there a way to traverse the portal and somehow use a magic action to close it and bring it with you?
I had a DM allow me to find one of these in our adventure. When the rest of the party was down and out and the two stone golems were turning to focus their attention on me, I took my action, laid the WotW on the ground, and jumped in, feet first. The DM stammered, "But...but you don't know where it's going to open!" To which I replied, "Anywhere is better than here!"
