Electricity Discharge (recharge 6): A Giant electric catfish can generate a pulse of electricity. Every creature within 10 feet of the Giant catfish takes 2d6 points of lightning damage and is stunned until the start of the Giant catfish’s next turn. A successful DC 13 Con saving throw reduces damage to half and negates the stun.

Swallow: A swallowed creature is blinded and restrained but no longer grappled. It takes 1d8 + 4 acid damage automatically at the start of each of the Giant catfish’s turn. Only one Medium creature or two Small creatures can be inside the Giant catfish at one time. A swallowed creature is unaffected by anything happening outside the Giant catfish or by attacks from outside it. A swallowed creature can get out of the Giant catfish by using 5 feet of movement, but only after the Giant catfish is dead.


Environment: Non-arctic

Organization: Solitary or school (5–8)

Giant electric catfish make their homes beneath submerged logs and in streambed pits where they face upstream with their mouths open, swallowing everything resembling food that tumbles or floats into their toothless maws. They favor dank, dark, slow-moving water with limited visibility. They are nocturnal hunters and venture out a few hours after sunset to hunt.

Giant electric catfish are about 8 feet long but can grow to lengths of 12 feet or more. Their bloated bodies are generally gray or brown in color, fading to a dull white or cream on the underbelly. Their eyes are small and positioned on either side of a wide, round snout. Three sets of barbels (feelers) are located around the mouth. Unlike many fish, a Giant electric catfish has no dorsal fin.

Giant electric catfish are territorial, and the defend their realms with great ferocity. Before engaging in combat, when threatened or facing a potential enemy, an electric catfish generates a pulse of crackling electricity in an effort to intimidate or discourage would-be predators. Failing this, the Giant electric catfish enters combat and bites its foe.
