Stillness at Zero

Choose one creature you can see within range. The target must make a CON save or become paralyzed and immune to forced movement for the duration. It repeats the save at the end of each of its turns. On each failed save after the first, it takes 33 (6d10) cold damage.

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