Tale of Diep:Octrax

''Purple. Strong. Stealthy. Those words describe Octrax, the leader of the eight-sided polygons. He is the eighth and last Disciple to be created, and following in his brothers' footsteps, he put in motion the creation of defensive polygons we know as Nest Defenders. Like the others, he resides in a fortress where he oversees as many of his octagon subjects as he can. Unlike the others, he tends to lurk in the shadows... ''

Overview
Octrax is one of eight Disciples of the Polygons. He is technically the youngest of the Disciples, since he was created last, but is considered just as powerful as the others (and more mature than .) He represents the Octagons and every defender associated to them. Octrax, along with the other Polygon Disciples, are located within the center of a Polygon Fortress, found rarely throughout the Realm. In the game mode where the Polygon Mother herself is fought within a massive structure, each Disciple, including Octrax, has an independent space in which where they are battled. He lies within the Octagon Fortress, a structure filled with the Octagon-based inhabitants and the keepers that await any intruders. They will be fought first before facing down the ruler of them all.

Design
Octrax is a purple octagon with two smaller octagons bound together with smaller octagons to the body, like the other Disciples. On the bottom of his body is a spawner. One of the smaller octagons has a sledgehammer-like mallet with gold accents on the faces and handle. The other hand has a scythe-like weapon, which looks (and functions like, aside from firing debuff bullets) almost exactly like the 's Slayer component. Said hand has armor on the area where the scythe is held by the octagon hand. Octrax's main body has a gray helmet that barely covers the top of his "head" and has two gold "wings" extending to the left and right, think of it like the gold thingies on DC superhero Flash's costume. The middle of the helmet has a trapezoid protrusion from the bottom edge to make room for an octagon gem like the other Disciples. Octrax also has octagon-shaped barrel gray armor around his body, arms, and hands.

Stats
Octrax has a total HP of 50,200. He has 40% resistance to damage. Octrax regenerates very slowly, 4 HP every second for all parts, regeneration does increase by 500% if left alone for over two minutes (though it's rare for that to happen). He has a base body damage of 70 HP.

Octrax can summon various enemies like other Disciples, ranging from octagons and Crashers, bosses like and, or even ,  or. He has an ability to summon many as well. In Phase 2, where his hands lose their weapons, Octrax can summon boss entities.



Octrax can swing his hammer around to block bullets and other ammunition, sending it back at players. The hammer can also be used to hit players for medium damage, dealing a bit of knockback to them. He can also use his Slayer weapon as a short, high-damage dagger, a longer medium-damage short sword, and an extended form with barrels as a bullet storm weapon. Each time when changing forms, the old form retracts back in completely and the new form extends out.

The bottom spawner constantly spawns 1 Crusher, 2 Phasers, and 3 Semi-Crushers, in that order. Size is randomized. However, it occasionally will release a storm of 15-27 of one Crasher type. Octagons are also released occasionally, 50% chance after the Crashers. Very rarely, Octrax will spawn 4 Assassinators. There is a limit of 100 Crashers of any type and 80 octagons at once at any time. Neither limits apply to octagons and Crashers used in Octrax's attacks.

Octrax has little magical powers, and otherwise relies entirely on his bulkiness and stealth, which is unusual given the first characteristic is not usually associated with the second. He can summon polygons, though, like throwing Alpha Octagons at players and directing his Crashers into formations. Mostly though, he lurks in the shadows and body slams into players with his weapons.

Phase 1
During this phase of the battle, he is in the center of the arena, staying still as more players join in. He is invulnerable during this as a transmission from the Polygon Mother warns the tanks once more about the dangers they are about to face down, and that Octrax should be left alone. After the transmission ends, Octrax stands up and speaks his one quote right after he makes his first and only attack, which blocks the exit with a wall of normal octagons until he gets defeated. Polygons created by Octrax will not reward any EXP.

Octrax is invulnerable during Phase 1, and only when both his hands' HP reaches 0 will cause Octrax to enter Phase 2. The hands that are "destroyed" loses all of its weapons and becomes invulnerable, but useless. Attacks that require the weapons will be disabled.


 * Shieldwall: Octrax summons about 50 Octagons to block the exit. They link together and form an impenetrable but bouncy wall. Tanks that try to exit from the inside will get bounced back, while tanks that try to come in will be bounced away as well. Damage is not sustained by those who are bounced.

Watch your back...


 * Slide: Octrax's main form of movement in this phase. Octrax moves around in the four cardinal directions and along diagonals. He can move during attacks unless otherwise stated.


 * Bell of Doom: A bell sound can be heard as Octrax vanishes in a blur. He moves so fast that he's almost invisible, then the bell sounds again and Octrax stops near a player, then blasts them with the Slayer weapon and anything else that happens to be in the way.


 * Linear Strike: Octrax summons a line of 10 Beta Octagons, then summons one Alpha Octagon. He hammers the Alpha Octagon into the line of octagons, sending the last one in the line flying outwards like a Newton's Cradle. Octrax continues hammering very quickly until the Alpha Octagon has been sent flying. Octagons bounce everywhere up to 5 times, dealing medium damage to anything that's hit. If they hit each other, that will not count as a bounce.


 * Billiard Strike: Similar to Linear Strike, but the octagons are arranged in a triangle and there are 15 of them. When Octrax smashes the Alpha Pentagon, it flies into the triangle of octagons, sending all 16 flying. Same bounce mechanics apply.


 * Heavy Crush: Summons a wave of 14-22 Crushers and joins all existing Crushers into that group, then directs it around like a swarm of . Can control them like a Necromancer with a repel function.


 * Phase: Same as Crusher Swarm, but done with 18-31 Phasers instead.


 * Light Crush: Same as above, but done with 25-45 Semi-Crushers instead.


 * Shadow Militia: Octrax will raise his left hand as it glows brightly. Suddenly, 15-28 Assassinators will be summoned.


 * Cloak and Dagger: Octrax vanishes and moves around invisibly, rushing to nearby tanks and dishes out 2-5 strikes per tank, with low damage per strike but adding up with each strike. Used 6-14 times on targets. Octrax uses the Slayer weapon in its extended form without barrels here.


 * Missile Turret: Octrax extends the Slayer weapon with its barrels if it isn't already extended, and fires off 20 homing missiles (War Machine variety) that track down players. Missiles have 80 health and deal 60 damage on impact.


 * Supernova: Octrax spawns a mixed group of 42-60 (Phasers, Semi-Crushers, and Crushers) Crasher variants and gathers those and all existing Crashers in one spot, then sends them out at an incredible speed, the Crashers dealing low damage to a good deal of tanks in the battle due to the number of players fighting Octrax.


 * Shockwave: Octrax pounds the ground with his hammer, sending out a rippling shockwave in the ground in a radial pattern (like when you throw a rock into a pond.) Tanks hit by the shockwave, which dissipates after 65 background tiles in radius, are dealt damage scaling from how close they are to Octrax when he pounds the ground. It's medium-high up close and low far away.


 * Bulk Up: Octrax's body shines white, and he receives for the next 45-60 seconds while increasing his base movement speed by 25%. Only happens 5 times during Phase 1, it happens every 7 attacks.
 * Hammer Punch: Octrax shoves his hammer weapon bluntly into a tank, dealing medium damage and knocking back slightly. He then will attempt to whack tanks with one of the actual hammer sides five times, dealing high damage and healing himself for the damage dealt. Not used more than 4 times per fight in this phase, happens every 8 attacks.


 * Cyclone: Marks the transition to Phase 2 once both of his arms looses their weapons. Octrax's arms detach from his body and rotate around him as he charges tanks to body-slam them and deal high damage if anything comes in contact with his arms. His head is during this attack.

Phase 2
When Octrax's hands are disabled, he enters Phase 2. Octrax moves faster and teleports around to disorient his enemies using Slide II. Bullets fired at the hands will go through them. The frame armor around his body, hands, and arms also shatters and disappears.

Octrax can now summon bosses such as the, , , , and. All of these bosses will reward EXP excluding the minions.

During a boss summon, Octrax will be invulnerable until boss/bosses dies. He can not attack while a boss is in session. After the boss dies Octrax will resume attacking until the loss of 5,500 HP has been reached. For every milestone of HP lost, Octrax will summon a boss or multiple bosses as the following:

Boss Spawning Order:

 * At 29,600 HP: The Pulsar or The Vanguard.
 * At 24,100 HP: The Spreader or The Collider.
 * At 18,600 HP: The Spreader + Pulsar, or two Vanguards.
 * At 13,100 HP:  Two Vanguards + Pulsar or Collider + Pulsar or Spreader + Vanguard.
 * At 7,600 HP:  Two Spreaders or four Pulsars or Three Vanguards or Umbra.
 * At 2,100 HP:  Three Colliders or four Vanguards or three Spreaders or six Pulsars or Umbra + two Vanguards.
 * At 800 HP:  Two Pulsars, Spreader, Vanguard, Collider, and Umbra.

Attacks
During the between sessions of the boss summoning, Octrax will do these attacks randomly. If Octrax reaches a 5,500 HP mark, he'll become invulnerable and wait for the attack to be finished.


 * Slide II: Octrax's main form of movement, moving around in the four cardinal directions and along diagonals. He can move during attacks unless otherwise stated, and now teleports randomly at random intervals and moves 50% faster.


 * Bell of Doom II: A louder and deeper bell sound can be heard as Octrax vanishes in a blur. He moves so fast that he's almost invisible, then the bell sounds again and Octrax stops near a player, then body-slams them to deal very high damage.


 * Linear Strike II: Octrax summons a line of 16 Beta Octagons, then summons two Alpha Octagons. He body-slams the Alpha Octagons into the line of octagons, sending the last one in the line flying outwards like a Newton's Cradle. Octrax continues hammering very quickly until the 2 Alpha Octagons have been sent flying. Octagons bounce everywhere up to 7 times, dealing medium-high damage to anything that's hit. If they hit each other, that will not count as a bounce. Octagons also move 20% faster than before.


 * Supernova II: Octrax spawns a mixed group of 68-102 (Phasers, Semi-Crushers, and Crushers) Crasher variants and gathers those and all existing Crashers in one spot, then sends them out at an incredible speed, the Crashers dealing low-medium damage to a good deal of tanks in the battle due to the number of players fighting Octrax.


 * Shockwave II: Octrax jumps and smashes the ground with his body, sending out a rippling shockwave in the ground in a radial pattern (like when you throw a rock into a pond.) Tanks hit by the shockwave, which dissipates after 85 background tiles in radius, are dealt damage scaling from how close they are to Octrax when he pounds the ground. It's high up close and still low far away, however, damage is increased from the original Shockwave.


 * Border Wall: Octrax shines a metallic gray, becomes Invincible, and spawns a shitload of Crashers (250+) that form a wall in front of him. They don't attack, and tanks have to destroy the wall of Crashers to resume fighting Octrax. Once 80% of the wall is destroyed, all remaining Crashers become active again and Octrax returns to normal.


 * Collateral: Octrax summons 25 normal Octagons, and controls them like drones. Controlled octagons have the same health and body damage values, and move as fast as a Large Crasher.


 * Fortress: Places down 8 Octagon Defensive Turrets, Beta Octagons with Dominator Auto Turrets atop them in an octagon formation surrounding him. They have 1200 health and fire as fast as a normal Dominator. Bullets have infinite penetration and the damage of a Destroyer's, like normal Dominator bullets do.

The End of Octrax
When Octrax reaches the 800 HP mark and after the bosses are defeated, a transmission from the Polygon Mother reminds the tanks about what they are about to face with. Octrax will perform a normal Collateral attack, and summons a dense wave of 8 Alpha Octagons that slowly expands out from him. Octrax will actively be moving around trying to avoid any form of enemy ammunition, while the expanding wave of Alpha Octagons will follow. The Alpha Octagons have their usual health.

The bouncy wall of 50 octagons created from the beginning of the fight suddenly breaks apart and become normal octagons that are being controlled by Octrax as extra drones. However, destroying Octrax himself is the only way to win the fight. Just deal enough damage and it's over.

If every tank present during Octrax's final moment has died, a transmission from the Polygon Mother to those engaged in Octrax's battle will appear, her congratulating them for "sparing" Octrax. The entrance to his fortress will be blocked for 45 minutes, and everything will get reset.

However, if Octrax's HP finally reaches 0, he kneels down and white cracks begin forming all around his body, any pentagon in range around him starts to loose their color, turning into a gray. Octrax then suddenly vaporizes with a white flash on the screen, leaving only the helmet behind on top of a pile of ashes. All octagons and polygons associated to them with a huge radius around the death of Octrax will have halved HP and resistances. Any octagon-based bosses/ that were present near the fortress where Octrax has been defeated will greatly reduce in HP and Resistances, Superior Octagon nests will stop spawning octagons for a long time around its destruction area...

Trivia



 * Octrax's main physical traits are being bulky and stealthy, two traits that don't usually go together. But it works fine here, so shush.


 * His original design had 3D treads on the bottom of his body, but it was ultimately decided that the treads were too hard to replicate in the Diep.io art style.
