Once you finish a raid on a fruit that you have 600 mastery on (and any other requirements for fourth sea), and have it fully awakened. The Mysterious NPC at the Eglise de la Prophetie says
"...You are ready,"
The two options are <What?> and <Take me back.>
Saying What? follows up with:
"But are you sure?" (the other option just takes you back)
If you say yes, you're teleported to the arena with rip_indra, desperation. You can't unstore a fruit during the fight, you can't eat any fruits you unstored previously, you can't change fruits in the shop menu, etc.. You're forced to use the one you came in with.
Rip_Indra still had a fighting chance before you had v4, now, he's forced to use everything at his disposal if he wants to be the one to get out of the fight, whether it be alive, or victorious.
Phase 1
He uses Triple Dark Blade, and upgraded versions of it's moves. (With damage changes ofc) and a sort of Dark Dagger v2.
Moves:
Ten Thousand Slices (TTK-Based)
Rip_Indra teleports slightly above you and starts the barrage of slices, when it finishes, he smashes two of the three swords on your head, sending you straight down.
Pitch Black Slashes (TTK-Based)
Rip_Indra teleports to the middle of the arena, and spins the blade on the ground, releasing waves of darkness. If you're hit by one, you get slashed continuously for about a second or two. Which stunlocks you.
Masterful Pierce (Dark Dagger)
Rip_Indra dashes to the nearest player, hits them with his knee before impaling them with dark dagger, which sends them backwards with a large shockwave. (The shockwave is AoE, so if anyone is right next to them, they also get knocked back.)
Humiliated (Dark Dagger)
Rip_Indra spins as if throwing a shot put ball, and throws the dagger to a random player. If the player tries to move out of the way, the dagger homes onto them. When it makes contact, Rip_Indra does a combo by kicking them around and teleporting to catch them and hit again.
Phase 2 (Half HP)
Rip_Indra burrows his head in his hands, and tears out the Ghoul V4 horns. The health bar turns red, before turning black as he activates a variation of Ghoul V4. The Arena gets covered entirely by the domain expansion gear of Ghoul V4, which releases tentacles that are completely jet black, so you see just the silhouette basically. Rip_Indra is invincible until all of the tentacles are defeated, meanwhile, he's on his knees in the middle of the arena, with one hand to the ground, as if he's maintaining the domain by hand.
There's 4 tentacles that each have 70,000 HP. They smash down whenever someone is nearby, or can flail around when there's a player in the air around them.
Phase 2.5 (When the tentacles are defeated)
Rip_Indra still has Ghoul V4 active, so the domain is kept intact.
Moves:
Crows of Night
Rip_Indra raises a bunch of crows made of shadow from the domain, and sends about 3-5 to each player. They deal 1000 damage each, and hit without using an Instinct Dodge or disabling Instinct. (Passes through it)
Cloud of Blight
Rip_Indra summons a raincloud that spews out damaging pellets of darkness. It occasionally spawns thunder, like Rough Sea. The "rain" drops don't deal much damage, but they slow down on hit.
Bout of Light
Rip_Indra pulls out the sword for the Light fruit, and uses the X move before storing the sword. His attack can't be cancelled and completely stops a player from moving, but if several people are fighting him at once, then it leaves him vulnerable.
Doubt of Might
Rip_Indra slash towards a player, it stunlocks on hit. Then he teleports over to them, and impales them with dark dagger. They're inflicted with a debuff that lowers their damage for about 10 seconds. (Lowers by 50%)
Phase 3; 1 HP. (Last Stretch)
A cutscene starts where Rip_Indra tries to activate all 6 V4 transformations one after the other. He already had Ghoul so next he activates Angel, then Shark, then Human, Mink, and finally Cyborg.
The players are spread out at the edge of the Arena, and can't use any abilities. A feature of each V4 is everywhere on the Arena. There's the tentacles from Ghoul, the tornadoes from Mink, whirlpools from Shark, silhouettes of Rip_Indra flashstepping so much that it creates solid afterimages, that try to slash you if you get too close, tesla coils that stun you when you get close, and an aura from Angel that slows you down the closer you get to Indra.
Once a player gets there, they have a prompt:
<Finish it? Once and for all?>
If they click Yes, then they pull their arm out to punch Rip_Indra, and the screen goes black.
Sealed King:
"You did it. You defeated him... once... once and for all."
The players get teleported to Fourth Sea, and get the title "Rival of God". The default title color is rainbow like the Rainbow Saviour aura color.
Rip_Indra drops 10,000,000$. (Since you can only fight him once.) and give a 2h Double XP boost. As well as the "Broken Dark Blades". A variation of Triple Dark Blade that has the white aura fizzing in and out every few seconds, the blades are chipped, and the moves are immensely downgraded, but still do insane damage.
