Update 4 — Eternal

Update 4 adds the Eternal Zone — a new map layer past Celestial that needs 5 Billion kick power to enter and gives +5,000% luck.

Astral and Phantom mutations drop here, plus player trading so you're not stuck on bad RNG. This guide covers the Eternal Zone, the 5-item Phantom Event, and Admin Abuse luck windows that can stack up to 96x.

New Area: The Eternal Zone

The Update 4 expansion introduces the highest tier map to date, located right after the Celestial Zone: the Eternal Zone.

• Entry Requirements: Accessing this zone requires immense power. Testing confirms that an absolute Perfect Kick with a minimum base kick power of 5 Billion (5B Power) is required to cross the threshold and land inside.
• Zone Buffs: Landing in the Eternal Zone rewards players with a massive baseline +5,000% Max Kick Luck multiplier, drastically increasing the drop rates of high-tier rewards.
• Pro-Tip: When the server-wide Soccer Event (Cosmic Kicks) is activated, players can launch the ball significantly further, making it much easier to hit the absolute limits of the zone's luck scaling.

New High-Tier Mutations

Update 4 completely shifts the meta by introducing two god-tier mutations that officially surpass the Rainbow trait in raw power and value:

1. Astral Mutation

• Rarity Tier: A permanent Index addition that ranks higher than Rainbow (50x vs 40x).
• Visual Effects: Features an incredibly unique cosmic aesthetic, surrounding your character with a high-density, swirling celestial aura.
• Stat Scaling: Shares identical top-tier scaling with the Phantom mutation (e.g., an Astral Strawberry Elephant at max level pulls in a massive 218 Trillion/s).

2. Phantom Mutation

• Rarity Tier: Event-exclusive trait at 35x on launch (lowered to 25x in Update 6).
• Visual Effects: Grants a translucent, ghostly visual appearance where the brainrot model floats directly through and merges with your player avatar.
• Acquisition: Can only be rolled via the limited-time Phantom Event.

Limited-Time Event: The Phantom Challenge

During server-wide events, the Phantom Weather event will trigger dynamically.

• Core Mechanic: While active, every Lucky Block kicked has a flat 3% chance to transform into a Phantom Lucky Block.
• Index Milestone: To fully complete the event and unlock the ultimate Phantom rewards, players must collect all 5 specific Event Brainrots:
  1. Cholon
  2. Ambal
  3. Lo Primos
  4. Nikico
  5. Telepadon

Eternal Brainrot Database

Five legendary "Eternal" class brainrots have been added to the bottom tier of the Index. Due to their abysmal direct drop rates, they are currently the rarest commodities on the market:

Note: Legacy brainrots (such as the Pot Hot Spot) have also received new Molten and Shadow variants in this update to help fill out your collector Index.

Core Mechanic: Player Trading System

To help players bypass the brutal RNG of the new blocks, Update 4 officially introduces the Player-to-Player Trading System!

• How to Use: Approach any player in your server and send a "Trade Request" to open a secure, dual-confirmation trading menu.
• Current Market Value Reference (Based on High-Tier Community Trades):
  • 1x Diamond Professor 67 (Eternal) ≈ 2x Maxed Rainbow Celestial Brainrots
  • 1x Phantom Mutation ≈ 1x Equal-tier Rainbow Variant
  • 1x Astral Mutation ≈ 1x Equal (or slightly higher) Tier Rainbow Variant

Pro Developer Tips & Economy Strategy

1. Don't Rely Solely on Solo Kicking: Even under extreme stacking conditions—such as a global 12x Server Luck event multiplied by individual gamepasses pushing your luck to 96x or higher—the direct drop rate for a raw Eternal drop remains incredibly low.
2. Trade to finish the update: Phantom drops are RNG-heavy. Trading duplicate maxed Rainbow Celestials for the Eternal pieces you need is often faster than grinding alone.
