Earthmound Dweller [>>>] (primal, transmutation) The duende shrinks to the size of an ant, allowing them to enter very small tunnels within the earth such as anthills or termite mounds. Their Speed decreases to 5 feet. They can remain in this size until they end the effect by spending a single action, which has the concentrate trait. If the duende is underground and a creature hits the space they're occupying with a Strike (hitting automatically) that deals 5 damage or more, the duende is expelled from the tunnels, returns to their normal size, and takes bludgeoning damage equal to the damage from the Strike.

Fool's Gold [>>] (occult, illusion) Frequency once per day; Requirements The duende is holding brown or yellow earthen objects, such as ginger or animal dung; Effect The duende makes the objects look, feel, and smell like gold trinkets of a similar size. A creature that touches or Interacts with an affected object can attempt a DC 18 Perception check to disbelieve the illusion, and a successful DC 20 check with Crafting or an appropriate Lore skill (such as Mining Lore) reveals their true nature. The effect ends if the objects are exposed to sunlight.
