The Witcher Continent

You use magical energy to conjure a portal 5ft wide and 6 ft tall, the center of which is another location. The portal can teleport anything that can fit through it to a location you know. If you use your reaction to end the portal while something is only partially through it, the portal instantly closes, severing the creature or object in two. You can teleport to a place you don’t know as long as you have an item from that location. For instance you can teleport to a stranger’s house if you have a piece of their cutlery or something of the like. This is far more complicated however and requires a DC 20 Spellcasting check. If you succeed, you teleport into the center of that location. If you fail, you teleport to a random location within 2d10 miles of the intended location.
