Portal Potion

My first idea is for this mechanic to be applied to a new staff, but since we already have enough weapons, I have turned it into an item.
It would be an item that would brew portals. Using the item for the first time next to a wall, it would create your portal, using it again after that it would teleport you to that portal (similar to a portal-gun). The radius of effect of the item would be limited; if you tried to use the item to stop teleporting too far, it would not work and would show the space where it can be used with a large purple mark on the ground.
Maybe we had to deal with the burden of having several players waiting for you on the portal, so maybe he could be invisible to others and visible to us. I thought it would be interesting that when you teleported to the portal you were thrown from the inside, with a fall animation (Maybe it could also take a little damage).
If you do not understand, I'm sorry, it's a rather difficult mechanic to write.
Correct me right below.
