Giant Conger Eel

At an average length of 1d4+3 feet and a maximum weight of 159 pounds, these fish live in pits or holes in coastal areas or reefs, known as “eel holes”, and only emerge to hunt at night. While occupying an eel hole, a conger has a +6 bonus to stealth checks and AC. It may bite, or threaten to bite, if irritated. Giant conger eels are even larger, being 1d12+7 feet long. They occupy correspondingly larger caves and holes, but use them in much the same way as their smaller kin.
