Description
According to legend, Aarthron is an eldritch horror standing 2,000 feet tall with black skin, slimy like the skin of a squid, with purple veins running all throughout his body. His body is mostly humanoid besides his massive fists and his head that looks like an octopus with the snout and teeth of a shark as well as the eyes of an angler fish. His blood is purple and is toxic to every creature.
Aarthron is so powerful that just by looking at him you instantly become his slave for the rest of your existance and will eventualy die serving him. It is said that only some of the most powerful beings have even a small schance of resisting this god-like power that Aarthron possesses.
Aarthron was locked away by the gods at the bottom of the ocean and with his vast power, intellect, and manipulative tactics, he has gathered a following known as the "Cult of the Deep", devoted to praising Aarthron and eventually setting him free of his sea imprisonment.
Aarthron only seeks destruction for all of the mortal realm and become more powerful by consuming the realm. Once he is done with the mortal realm he shall become more powerful then the gods that locked him away and consume them as well.
dang.
that is one dang-gerous beast!
eeeeeeeeeyyy
tis the point lol
wow
This is a great monster! I might use it as a boss in my next campaign!
Cool! Glad to hear!
This is stoopid and i love it
😎cool
for some reason this reminds me of the eldritch horror Cthulhu
The slam attack needs to deal more damage tho
I have never seen a monster with more than 3 zeros in its HP. is it even possible to beat that thing?!
That is true, but still, 4d10+10 can do 50 damage. Quite a lot when you think about it.
GO AND FIND MY EXALTED DEATHBRINGER DAMN YOU
I would like to propose a weakness:
Whenever someone brings up the name Cthulhu, Aarthron takes 1d100 psychic damage and is stunned for 5 rounds as his mind reels from someone daring to utter the name of his eldritch rival within his presence.
This thing could kill the Terasque
