Watery Sphere

Create a 10-ft. radius sphere of water centered on a point within range. Creatures in the area must make a STR save or become restrained inside the sphere. A restrained creature repeats the save at the end of each of its turns. As an action, move the sphere up to 30 ft.

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