Titan Clinch

Grapple one creature within reach using Athletics with advantage. While grappled this way, the target takes bludgeoning damage equal to your STR modifier at the start of each of its turns and has disadvantage on checks to escape unless larger than you by two or more sizes.

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