  • Echolocation. The ghost whale can’t use its blindsight while deafened.
  • Siege Monster. The ghost whale does double damage to objects and structures.
  • Sunlight Sensitivity. While in sunlight, the ghost whale has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
  • Turn Resistance. The ghost whale has advantage on saving throws against any effect that turns undead.


  • Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 29 (4d10 + 7) piercing damage. If the target is a Large or smaller creature, it must succeed on a DC 16 Dexterity saving throw or be swallowed by the ghost whale. A swallowed creature has total cover against attacks and other effects outside the ghost whale. If the ghost whale dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement.
  • Sonic Wave (Recharge 2-3). The ghost whale sings an eerie whale song in a 90-foot cone. Each creature in that area must succeed on a DC 16 Constitution saving throw or take 24 (7d6) force damage and be stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.


Swimming under the surface of the sea are enormous undead whales. Encountering one of the horrors can be one of the most terrifying moments for an adventurer.

Second Life. These whales have returned from the land of the dead with a vengeance. Ghost whales will target whalers and fisherfolk first. However, they will attack almost any ship and attempt to sink it.

Below the Surface. Ghost whales are one of the biggest creatures in the sea, usually about 100 feet long. Intelligent mammals like whales and dolphins can sense something is wrong with these grim creatures and avoid them.

Undead Nature. The ghost whale doesn’t require air, food, drink, or sleep.
