Anchor

For the duration, you become a magical tether between realities for yourself and your allies. In a 15-foot radius around yourself and that moves with you, you and any number of creatures you choose within the radius cannot be moved or teleported unwillingly.

At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the effective radius increases by 5 ft. for each slot level above 1st.

When casting this spell using a spell slot of 4th level or higher, any number of creatures you choose within the radius cannot teleport in any way. Any attempt to teleport results in the creature having to make a Constitution saving throw, taking 4d6 force damage on a failed save, and half as much on a successful one. The amount of force damage dealt in this way increases by 1d6 for each spell slot level used above 4th.
