  • Keen Smell. The oil shark has advantage on Wisdom (Perception) checks that rely on smell.
  • Liquid Fire. The oil shark is only known to inhabit the Sea of Fire in the Plane of Molten Skies and the Plane of Fire, and therefore can breathe in liquid fire and underwater.


  • Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 28 (4d10 + 6) piercing damage plus 14 (4d6) fire damage.


An immense, eyeless shark over 20 feet long feet darts through the flames, its blackish-blue, metallic scales gleam with blackish oil.

The Sea of Fire located on the Plane of Molten Skies and the Plane of Fire is home to strange aquatic life (if they can be called that), but perhaps none is stranger than the mighty oil shark. These creatures spend their days swimming beneath the burning surface of the Sea of Fire, searching for prey. Their diet consists of other aquatic creatures found in the Sea of Fire such as fire crabs, oil worms, and the great fire whales. The latter is a particular favorite of the oil shark, and while the typical great fire whale outweighs (and is generally larger) than the typical oil shark, an oil shark pack has been known to attack and kill a lone fire whale with ease. Oil sharks have never been encountered outside the Plane of Molten Skies or Plane of Fire though sages believe the oil shark can exist in normal water.

Oil sharks are completely blind and rely completely upon their “sonar” to hunt their prey. Oil sharks generally behave as other sharks; circling their prey before striking with their powerful jaws. Non-aquatic prey (i.e., creatures that breathe air) are often grasped in its jaws and dragged below the surface of the burning sea where it drowns in the oily waters. Their oily hides allow them to glide smoothly and quickly through normal water.

Oil sharks are a delicacy of volcano giants and are often hunted by such creatures. The thick, metallic hide of an oil shark is prized by salamanders and they often hunt these creatures, kill them, and sculpt armor from the hide. Oil shark armor is detailed in the sidebar.
