A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Description
Nightmare beasts are enormous quadrupeds that stand 20 feet tall, or 40 feet tall when rearing on their hind legs.
A nightmare beast’s legs end in claws, enabling it to climb well despite its size. Its skin is thick and tough, and its teeth are long and sharp. A pair of long, curved tusks jut from the sides of the beast’s mouth, and its large red eyes glow in the dark. The creature smashes through structures and fortifications with ease, and it doesn’t hesitate to rend foes with its claws and gore them with its tusks, but its most devastating attack is its magical ability to disintegrate foes with its terrible gaze.
Powerful spellcasters create nightmare beasts to serve as living siege engines. A single beast can lay waste to entire cities and armies.
The Nightmare beast was an epic level encounter. The only thing that is intimidating is the disintegration. How does a 20 foot tall at the shoulder creature do 14 damage with a claw? A clay golem does more damage with its fist than a "living siege engine."
You'd better post it to homebrew, it sounds awesome.
this thing is smaller than Clifford
Since this can be obtained by "powerful spellcasters" theoretically we can upgraded with various armor for more defense, control, & devastation.
"Siege Monster. The beast deals double damage to objects and structures."
It seems like he can
Just gonna leave this here so that I don't forget
As you peer out into the dark void of space, you suddenly catch sight of a massive shape looming in the distance. As it draws nearer, you realize with growing horror that it is a creature unlike anything you have ever seen before.
The Nightmare Beast is immense, its serpentine body writhing and coiling in the inky blackness of space. Its scales are as black as the void itself, and its glowing red eyes seem to burn with an otherworldly malevolence. Long, sharp teeth line its gaping maw, and razor-like claws protrude from its massive, muscular limbs.
As the creature draws nearer, you can feel an overwhelming sense of fear and dread wash over you, as though its very presence is anathema to life itself. Your heart pounds in your chest, and you can feel your hands shaking with terror.
You realize with a sinking feeling that you are completely outmatched against this monstrous creature. Its very existence seems to defy the laws of nature, and you can't imagine what kind of power could have brought such a creature into being. All you know is that you must do everything in your power to avoid its deadly grasp, lest you fall prey to the Nightmare Beast's insatiable hunger.
six words: not just a large displacer beast
for a miniature, I would recommend an evil blink dog that has a tusk attack: Tusk. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d6 +21) slashing damage, instead of bite. should I make a mini one? (to "Cspoons")
For a living siege engine, it doesn't do that much damage. It's gargantuan size and it claws do a measly 14 damage?! Like everyone else has mentioned, the only threatening a thing it has is a disintegration ray. Which I just noticed can easily be turned off with blindness/deafness or darkness spell because it needs to see.
And What concerns me is the lack of proficient saving throws. Those have been substituted for two legendary resistances. Now those are great and all but You guys really couldn't have been bothered to give it proficiency in strength and cons saves? Or any other saves for that matter?
Furthermore, what I find bizarre is that this creature is not immune to any conditions or resistant to any damage. A wizard with Greater Invisibility could just spam Fireball and easily smoke this guy. They can also cast Geas after burning through it's legendary resistances, now the party has their own living siege engine.
Overall, this creature is a pushover. There are so many spells that could subdue it in just 2-3 rounds. As long as the party spellcaster stays out of sight of this creature or the party rogue keeps popping off sneak attack damage due to the creature's ridiculously low passive perception, this thing is toast.
This guy is insanely overpowered
i get it's called a nightmare beast because it's big and scary but why name a monster like that when it doesn't have any sleep type spells
edit: i didn't see the Frightful Howl
Your name and picture clearly show that you are an expert in this field.
Is the average damage for its Disintegration Gaze wrong? From my understanding it should be 75, not 70. (avg roll for a d6 is 3.5, so 10 * 3.5 = 35, + 40 = 75)
yeah i get that but i'm more of a crab guy
Wow this thing is powerful, could use it as a main antagonist if I gave it a goal.
How do I create this? Like the ritual and components behind it?
There might be something in the Dark Sun campaign setting, but otherwise its up to the DM. Probably some sort of sacrifice, the Create Homunculus spell, and extra components.
Why not?
