Grinder-Widget
CREATURE 5Variant weak dig-widget
Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.
A dig-widget's face consists of a set of Infiltrator Thieves' Tools. They can be salvaged from a destroyed dig-widget with a successful DC 20 Crafting check. On a failed check, the tools are destroyed.
A creature with expert proficiency in Thievery can attempt a check to Disable a Device to damage a dig-widget. The DC is 20, and each success deals 18 damage.
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.
Critical Success The character is unaffected and automatically Escapes from the grapple.
Success The character takes 1d8+2 bludgeoning damage and then automatically Escapes from the grapple.
Failure The character takes 2d8+2 bludgeoning damage and becomes Clumsy 1 for 1 hour from wrenched and sprained limbs; the character remains grappled by the grinder-widget.
Critical Failure As failure, but 4d8+2 bludgeoning damage and clumsy 1 for 24 hours.
The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
