Earthen Entrapment

Choose one creature standing on loose earth, sand, mud, or soil within range. It must make a STR save or become restrained and blinded as the ground closes around it. A restrained creature may use its action to make a STR check against your power save DC, ending the effect on a success.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
