Twin Gates

The caster creates on a flat surface of at least 5x5ft a round portal of a bluish color. The portal itself it leads nowhere and cannot be entered. In order to use the portal created, another one must be created in a point located on the same plane of existence. You cannot have more than 2 active portals together and each portal created vanishes 8 hours after its creation. Creating the 2nd portal consumes an additional spell slot. If you try to create a 3rd portal then the oldest will come deleted and the 2nd will be linked to this. Looking through a portal that is connected to a other you can clearly see what's on the other side e items thrown through portals follow a normal pattern physical trajectory.
