Covered in vicious-looking crimson spines and sleek scales, the slithering bloodfin flashes through the lightless waters of the Netherdeep. As it swims closer, its toothed maw comes into view-just before it unhinges its jaw, clamps down on its prey, and swallows it whole. A slithering bloodfin looks like a giant eel with a head like a shark's. It magically siphons life energy from swallowed prey and uses that energy to repair damage to its own body. When a bloodfin dies, its body bursts. The resulting gore is toxic, threatening to infect nearby creatures, until it is dissipated by currents. Undead Large 5 ft., swim 50 ft.
