UNCOMMON CONSUMABLE ELECTRICITY MECHANICAL SNARE TRAP

Category snare

A hidden copper plate conceals a bag of electric eels. When a creature steps on the plate, the eels become agitated, and the creature takes 4d8 electricity damage (DC 21 basic Reflex). On a critical failure, the current causes the creature to become Stunned 2. The eels are unharmed after use, but the mechanism is broken as usual for snares.
