Description
The hulking alien that is the truest form to “the bottomless” the eldritch being that lies beneath the waves and who’s influence you see on the effects of evolution of the marine life that is closest to it. The stone looking shell is harder than steel and is the ultimate shield, its four crushing claws could rend a young dragon in two with one with of the muscle. It looks deep deep down, far below the breaking point of any creature, and slumbers in darkness waiting for a new interaction.
Lair and Lair Actions
Deep and dark miles beneath the first pocket of air, lies an almost alien world at the floor of the sea and ceiling of the Eldritch’s cage. Ruins of fallen ancient ships and horrific organisms coast around all the way to him.
Lair Actions
On initiative count 20 (losing initiative ties), the Crabju takes a lair action to cause one of the following effects; the Crabju can’t use the same effect two rounds in a row:
- Spill some of the contents of its stomach out making the water around deeply acidic and within 100 feet of the crab creatures that are not crabs need to make a dc 20 con save or take 5d6 acid damage
- Creatures that are within 100ft of the ocean floor must make a dc 20 wis save or the visions and voices of the thing beneath take hold and on a failed save give creatures that have and int above 6 and are not crabs take 4d10 psychic damage and cannot take reactions until the next lair action
Regional Effects
The region containing a legendary Crabju's lair is home of the ancient fathomless, which creates one or more of the following effects:
- Within 10 miles of the lair of the Crabju and its domain the currents are violent and strange, it is lightless and the mind swells from the pressure and some other thing that pulls at the back of any sentient creatures mind.
- Empower crustacean any crustacean within the 10 mile domain of the Crabju is underneath its control, and listens to its mental commands. All crustaceans gain 30 temp hit points, and gain +8 to attaks and +10 to damage(force)
If the crabju dies, these effects fade over the course of 10d100 days.
