Tale of Diep:The Harbinger

When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, "Come."

''I looked, and behold, an ashen horse; and he who sat on it had the name Death; and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword and with famine and with pestilence and by the wild beasts of the earth.''

Overview
The Harbinger is one of the four Final Sons who can spawn in Mega Fortresses. Being a Final Son, he is based off of one of the Four Horsemen of the Apocalypse, The Harbinger representing Death from the Book of Revelations. While all Mega Fortresses have the same layout, his is made of and ridden with bones and death-based enemies including the Bonys, Carcasses, and Ghouls.

The Harbinger was created by Panzer, alongside the other Final Sons, in his last hours before being sealed at the end of The Old Era. They were set to wake weeks before Panzer's freeing of his ethereal chains.

Design
The Harbinger is an odd figure. The body is a white skull, with black eyes that have glowing red lights, but depending on if its moving left or right, the front of the face will be more centralized in that direction. Near his sides are two smaller white tanks, with long, scythe-like extensions. From his back, is a Booster set-up and a long white tail made of spiky triangles similar to that of The Wolf, Adversary, or Second Witness.

Phase 1
In Phase 1 he looks as described above, but every 500 damage taken, he will lose one spike from his tail-like extension. It is made of twelve in total, so he will have 0 left by the entry of Phase 2 at 6000 health.


 * Claim: Griever-hook arrows with no chains attached will begin being placed around the arena one at a time pointing a direction. After eight hooks have been set, they will fire in the direction they're facing one at a time in the order they were placed. Hooks fired leave a bullet trail behind them.
 * Oath: Will slash both of his scythes together, and then leap at a player while pulling his scythes apart. Upon reaching his destination, he will slash his scythes inward again. If the player is hit, they will be Broken for 5 seconds and pushed away.
 * Ritual: Will raise his right scythe upward as it glows purple. From around him, a group of enemies randomly assorted from earlier in the Mega Fortress will appear. 50 'slots' worth of enemies will be spawned. Bonys will take 5 slots, Carcasses will take 10 slots, and Ghouls will take 2 slots. A random number of these enemies equaling 50 slots will be summoned. He will be Armored until all of them are killed.
 * Death Wave: Will swing one or both of his scythes at a 50 degree angle, and an arc of bullets will be fired out at every point on the angle.
 * Laugh: The skull's jaw will move up and down in a laugh position, before sweeping a laser at a random angle. The larger the angle, the slower it sweeps. The laser inflicts Unfocused and deals massive damage if touched.
 * Bone Dance: A series of bone-like projectiles will be thrown out from his mouth one at a time. Upon hitting a location, eight white Destroyer bullets will be fired out from them.
 * Bone Destroy: Like Bone Dance, but all projectiles are fired out at once creating a bullet hell. The Harbinger will be Broken for 8 seconds though.

Phase 2
When entering Phase 2, his tail of bones will be destroyed, and both of his scythes will be lost too, leaving him just a floating angry skull head.


 * Burst: Will fire a shotgun of three bullets spread apart, followed by four bullets spread within the same angle.
 * Charge: Will dash at a player and laugh, leaving a trail of bullets behind him.
 * Radiance: Will fire out eight spiraling waves of shots that will circle back in on him, followed by three bursts of ten bullet long lines in the cardinal directions, then the diagonal directions, before going back to the cardinals.
 * Curse: Will laugh, as the 20x20 tile area around him turns into lava tiles and moves with him for 10 seconds. While the aura is up, he can use other attacks.
 * Ghast: Will vanish, and then launch himself from the left fading out as he chomps, then does it from the right fading out as he chomps. Will do this four times, two from the left two from the right. There is a chance on the fourth that he will fakeout and quickly appear and bite down from the left again. Can target different players between bites.

Trivia

 * Despite the collective term of the Horsemen being 'The Harbingers' he is named as such because of the many harbingers, or signs, of death.
