Circle of Conjuration

You create a 10-foot radius circle centered on a point you can see within range. As an action, you may conjure a creature with a challenge rating of 5 or lower native to the plane matching the amulet used as the spell's material component. You may also dismiss that creature as a bonus action. The creature is under your control until the spell ends, obeying any commands given to it. Also, if a creature enters the circle's space, you can force it to make a Charisma saving throw. On a failed save, it is banished to the plane of existence matching the amulet used as the spell's material component until the spell ends. When the spell ends, the banished creature appears in the space it occupied before being banished, or, if that space is occupied, it appears in the nearest unoccupied space. Also, if you create the circle in the space of a teleportation circle, creatures that use the teleport or similar magic to appear in that circle take 3d10 force damage each upon entering the circle's space.
