Giant Electric Catfish

These nocturnal catfish grow 1d3 feet in length, and weigh up to 44 pounds at their largest. They are able to discharge electricity, causing Stamina damage (1, 1d3, or 1d4 points depending upon size). A creature taking 3 -4 points of Stamina damage must also succeed in a DC 10 Fort save or be stunned and unable to act for 1d3 rounds. A creature stunned in the water may drown if unaided. Giant electric catfish grow even larger (1d6+3 feet), and are able to give a shock doing 3d4 damage (Fort DC 15 for half damage), stunning creatures which fail a DC 10 Fort save for 1d5 rounds.
