Elastic Lariat

Choose one creature within range. It must make a STR save, taking 18 (4d8) bludgeoning damage and becoming restrained by your stretched limb until the start of your next turn on a failed save, or half damage with no restraint 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.
