Requirements A cybernetic zombie must use this reaction when the trigger is met unless its cybernetics are disabled;

Trigger The cybernetic zombie is reduced to 0 Hit Points;

Effect The zombie's damaged cybernetics explode, dealing 1d8 electricity damage in a 10-foot radius (DC 15 basic Reflex save). This ability destroys any technological items on the zombie.

When the Cybernetic Zombie hits 0 HP and its cybernetics are still online, it must immediately trigger self‑destruct as a reaction. This creates a small burst of electricity damage around it (basic Reflex save) and wipes out its built‑in technological gear.
Functionally, this turns the creature into a final area‑damage hazard at the moment of defeat and enforces “no easy loot” on its cybernetic weapon systems and rig—only PCs who disable the cybernetics beforehand can avoid the explosion and salvage intact hardware.
