Mutations

Full mutation tier list: multipliers, approximate drop chances, and how they affect brainrot income.

13+ Mutations

Beyond Rainbow

900x+ Luck

By Bloxron Editorial Team · Last updated May 29, 2026

In Kick a Lucky Block, the Mutation is the core mechanic that transitions players from "Average" to "Multi-Trillionaire." Mutations don't just transform the visual appearance of your Brain Rot Units; more importantly, they grant independent Value Multipliers that stack on top of a unit's base production.

To unlock the rarest evolutions, make sure your Luck is maxed out and you have enough Kick Power to reach the high-value drops in the later zones.

Mechanics & Rules

When designing your base or planning long-term progression, you must understand these fundamental facts:

Non-Stackable: Each unit can only possess one mutation at the time of drop. Once a unit has a mutation, it cannot be modified or added to via post-processing.
Unit Type Compatibility: Mutation multipliers directly amplify the $/sec of standard units. For Percentage Units (e.g., Dragons), the mutation does not change the percentage bonus (e.g., 2% remains 2%), but it drastically increases the unit's base cash value.
Spawn on Impact: Mutations are generated the instant the Lucky Block shatters. You must successfully retrieve the unit and place it in your base for the multiplier to take effect.
Distance Correlation: While random, the further the block lands from the starting point (i.e., entering high-tier zones), the higher the raw probability of spawning high-tier mutations.
Multiplier Logic: The mutation multiplier acts directly on the unit's base $/sec (Cash per second).

Calculation Formula:

Total Income = Base Unit Production × Mutation Multiplier

Mutation Tier List

Approximate base chances (x/y) and multipliers for the mutations currently documented in-game. Luck, zones, and events can shift real outcomes.

Mutation	Multiplier	Chance	Effect
Gold	1.5x	1/10	Increases your brainrot's earning rate and sale value by 1.5x.
Diamond	2x	1/25	Increases your brainrot's earning rate and sale value by 2x.
Plasma	4x	1/33	Increases your brainrot's earning rate and sale value by 4x.
Molten	6x	1/125	Increases your brainrot's earning rate and sale value by 6x.
Radioactive	8x	1/333	Increases your brainrot's earning rate and sale value by 8x.
Shadow	12x	1/2000	Increases your brainrot's earning rate and sale value by 12x.
Electrified	16x	1/5000	Increases your brainrot's earning rate and sale value by 16x.
Rainbow	30x	1/20000	Increases your brainrot's earning rate and sale value by 30x.
Virus	10x	Legacy	Legacy mutation from the old Virus Machine era. Update 3 replaced that system with the Weather Machine — existing Virus units may remain, but new Virus rolls are no longer the primary path.
Void	10x	—	Increases your brainrot's earning rate and sale value by 10x.
Astral	Beyond Rainbow	Eternal Zone	Permanent Index mutation from Update 4. Stronger than Rainbow with cosmic VFX. See the Update 4 Eternal guide for scaling examples.
Phantom	Beyond Rainbow	Phantom Event (~3% block transform)	Event-exclusive mutation from Update 4. Rolled during Phantom Weather / Phantom Event windows only.
Volcanic	TBD	Volcano Event (unlock first)	Update 5 event mutation. Unlock for 20 Volcanic Orbs at the NPC behind the Volcano Shop, then roll during the 2-hour Volcano Event. Exact multiplier is not yet confirmed in-game.

For event and zone-specific mutations, see our Update 4 Eternal guide (Astral & Phantom) and Update 5 Volcano guide (Volcanic). Current Weather recipes: Update 6 guide.

Maximizing Mutation Chances

Relying on "Blind Kicking" alone rarely yields mutations above Radioactive. High-level players combine the following systems to increase efficiency:

Luck Stacking

Multiplicative Scaling: Luck is not additive. The final calculation is:
Final Luck = (Base Luck + Gamepass) × Server Multiplier × Potion
Server Luck Boosts: Attempt pulls during 2x, 4x, or 8x Server Luck events for the best chance at Plasma tier and above.
Distance Buff: Entering the OG Area provides a built-in luck boost often exceeding 900x. This is the optimal time to use personal potions. If you need the full formula and event timing, use the Luck Guide.

Power & Precision

Perfect Kick: Precision timing increases distance and provides a slight "quality bias" at the moment of impact.
Zone Strategy:
- Early Game: Target Gold or Diamond mutations for initial capital.
- End Game: Top mutations like Rainbow need extreme distance and luck, so improving kick distance control is mandatory.

Survival & Risk Management

Top-tier units spawn at extreme distances, presenting a high retrieval risk:

Tsunami & Visual ID

Higher mutations often trigger more aggressive waves (e.g., Admin Wave).

Visual Quick-Check: If you see obvious high-tier VFX (e.g. neon smoke for Radioactive, prismatic trails for Rainbow), sprint regardless of the risk. If it's a low-tier glow and the wave is close, abandon it.
Stat Requirement: Impossible Waves in the Hacked Zone require a Movement Speed of 85+ for a reliable escape.

Regional Layout Strategies

As a player progresses, the base layout should evolve to maximize ROI (Return on Investment):

1. Early Zones (Rare - Epic)

Goal: Pure Quantity.
Strategy: Fill your base with any unit you can retrieve.
Layout: Replace non-mutated units with Gold or Diamond tiers as soon as they drop.

2. Mid-Tier Zones (Legendary - Mythic)

Goal: Multiplier Hunting.
Strategy: Mutations begin to outclass the base values of higher zones.
Layout: Prioritize any unit with a 4x (Plasma) multiplier or higher. An 8x (Radioactive) unit from a lower zone is often better than a standard unit from your current zone.

3. Advanced Zones (Divine - Hacked)

Goal: Balancing Survival and Power.
Strategy: Focus on "Anchor" units with high multipliers.
Layout: Keep your best Molten (6x) or Radioactive (8x) units in core slots. Only replace a strong Radioactive pull if you find a clearly better multiplier in-zone.

4. End-Game (OG Area)

Goal: The "Dragon" Meta.
Strategy: Exponential growth using a mix of high-base units and percentage buffs.
Layout: 60% Slots: your highest multipliers from the OG Area (Rainbow, Electrified, Radioactive, etc.).
Layout: 40% Slots: Dragon units (the % bonus multiplies the massive output of your mutated OG units).

FAQ

Q1: Can I "reroll" a unit to get a mutation later?

No. Mutations only generate at the moment of impact. While limited-time "Reroll" events occasionally occur, there is currently no permanent way to add a mutation to an existing unit.

Q2: Why did I get a "None" mutation in the OG Area?

Zones determine the loot pool and Luck floor, but mutations are still RNG-based. High luck significantly increases the chance, but does not guarantee a mutation.

Q3: Does the multiplier affect Rebirth points?

No. Multipliers only affect Cash production. Rebirth points are usually calculated based on your total net worth or highest kick distance.

Q4: Will I keep the unit if the Tsunami kills me?

No. If you die before reaching the shore, the unit is lost forever unless you spend Robux for an "Instant Revive."

Q5: Is Radioactive the same across all zones?

The multiplier (8x) is the same, but the base value is not. A Radioactive unit from the Hacked Zone is worth significantly more than one from the Rare Zone.

Q6: What graphics settings are recommended?

Set Graphics Quality to 5+ to ensure particle effects (like Radioactive smoke) are visible from a distance, allowing for faster decision-making.

Q7: How do I get Astral, Phantom, or Volcanic mutations?

Astral drops in the Eternal Zone (Update 4). Phantom requires the Phantom Event (3% — recipe updated in Update 6). Volcanic requires unlocking the mutation at the Volcano Shop (20 Volcanic Orbs) during Update 5 volcano cycles.

Q8: Is Virus still obtainable after Update 3?

The Weather Machine replaced the Virus Machine. Treat Virus as a legacy trait on older units; farm current meta mutations via zone luck, Weather events (see Update 6 for current recipes), Eternal/Phantom content, or the Volcano Event.
