Fastening Leap [>] The dig-widget Leaps up 20 feet onto a creature or object and attempts a corkscrew Strike against it. If the Strike damages the target, the dig-widget attaches to the target (typically to the back of a creature). This is similar to Grabbing the creature, but the dig-widget moves with that creature rather than holding it in place. While attached, the dig-widget can't use its corkscrew. The dig-widget can be Shoved off, or it can detach itself with an Interact action.

Sneak Attack A dig-widget's Strikes deal an additional 1d6 precision damage to flat-footed creatures.
