Seeking a more durable run
Consider Imposing, health, defensive choices and an attack that fits. Body Slam and More Mass are examples to inspect, not a guaranteed safe answer.
Improving damage
Inspect physical choices such as Claws and Sharpen if they support your attack. A guaranteed improvement to boss damage has not been measured.
Achievement goals
Read the current The Crabtain condition before committing to Carcinisation. The old instruction to collect all seven choices is unverified.

Everything is Crab Evolution Guide — 125+ Abilities and Six Affinities
This guide covers six Affinities, rarity, ten evolution examples and selection priorities, from early runs to Carcinisation goals. The old Branching classification and complete-list claims are not certified.
Once you understand the choices, review a build direction or the boss causing trouble. The pages below help connect evolution decisions with the next encounter.

Evolution choices change Darwin’s body as well as the way you play. The old guide describes three options per level and completely irreversible choices; read the actual evolution screen and specialisations. The four topics below explain what to check first.
🎲 Level-up choices
The old guide describes three evolution choices at each level. Check the actual screen and unlock pool; equal access to every Affinity and rarity, and the precise weighting rule, are not verified.
⚖️ Affinity weighting (old +10%/level claim unchecked)
The draft claims a matching selection adds 10% appearance chance and almost guarantees a matching offer after two or three picks. Neither the formula nor that guarantee has been independently verified.
🧪 Mutagen
A resource used for evolution decisions. The old map-drop rule, one-point reroll and ten-point upgrade of every option are unverified; use the cost and effect shown on the current screen.
✨ Rarity
Compare Common, Rare, Epic and Legendary effects in the Codex rather than selecting by color alone. The draft’s fixed prerequisite-to-rarity progression rule has not been verified.
Rarity overview
Old description: green frame and basic effects. Common choices can still support a later build; color, counts and exact progression must be checked in the current Codex.
Old description: blue frame and effects combining one or two Common choices. The fixed prerequisite rule is unverified.
Old description: purple frame and build-defining effects. A higher chance after two or three prerequisite choices has not been verified.
Old description: gold frame and a finishing role, ideally one or two per run. No fixed ideal count is established.
The old draft treats Branching as a red-framed boss-only rarity with permanent exclusions. This category is not verified; official material refers to Specialisations.
Gregarious
(Gregarious) Allies and cooperationAn ally-focused direction built around Charm. The old 12-ally cap and speedrunner-adoption claim are unverified; 12 simultaneous allies is an achievement target, not proof of a cap.
An ally-focused concept. Inspect Alpha, Pollinator and Tail Wag individually. The old maximum of 12 allies, attack/area-Charm effects and mandatory prerequisite sequence have not been verified for the current version.
- ▸ Alpha + Pollinator + Tail Wag: ally concept (effects unchecked)
- ▸ Pack + Courting: ally support concept (exact HP/damage effects unchecked)
- ▸ Antennae + Senses choices: detection concept (preemptive Charm claim unchecked)
Imposing
(Imposing) Durability and SizeA health-and-Size direction. Body Slam is one build concept, but the old universally strongest community ranking has not been measured or independently verified.
A durable concept combining health, Size and a suitable attack. Inspect Plating, Carapace, Shell, More Mass, Body Slam and Revenge in the Codex. The old best-build ranking, damage-reduction stacking and low-health-counter effect have not been verified.
- ▸ Plating + Shell + More Mass + Body Slam: durable concept
- ▸ Chonky + Carapace + Revenge: survival concept (effects unchecked)
- ▸ Body Slam + Sharpen: damage concept (interaction unchecked)
Predator
(Predator) Attacks and movementAn offensive physical direction. Efficiently defeating suitable animals can support progression, but an unlimited-leveling guarantee and instant kills are unverified.
An offensive concept using physical attacks and movement. Inspect Claws, Sharpen, Jaws, Sprint, Muscular Tissue and Carnivore separately. The old critical-hit, area-attack and meat-drop claims are unverified; do not assume a fixed three-step upgrade route.
- ▸ Claws + Sharpen + Jaws: physical-attack concept
- ▸ Sprint + Smol (Prey): movement/evasion concept
- ▸ Muscular Tissue + Carnivore: sustained-combat concept (effects unchecked)
Prey
(Prey) Evasion and movementAn evasion-focused direction. Inspect Smol, movement and feeding effects individually rather than assuming a universal combination.
An evasion and mobility concept. Inspect Smol, Elusive, More Eyes!, Slow Metabolism and any supporting attacks. The old claim that More Eyes! reveals attack warnings, and a hunger-meter effect from Slow Metabolism, have not been verified.
- ▸ Smol + Elusive + More Eyes!: evasion concept; not guaranteed immunity
- ▸ Forager + Herbivore: food-focused concept (exact effects unchecked)
- ▸ Prey + Predator (Sprint): mobile hit-and-run concept
Trickster
(Trickster) Range and Ability damageAn ability-focused direction that can include ranged or damage-over-time choices. Read each evolution’s effects rather than assuming every listed ability applies poison or parasitism.
An ability-focused concept using ranged or damage-over-time choices. Inspect Spit, Beak, Tentacles, Poisonous Saliva, Leech, Cortex and Synapse. Their old range, poison and cooldown combinations are not all verified; select support according to current descriptions.
- ▸ Spit + Poisonous Saliva: ranged-poison concept (interaction unchecked)
- ▸ Tentacles + Leech: contact/healing concept (interaction unchecked)
- ▸ Cortex + Synapse + Beak: ability-frequency concept (effects unchecked)
Carcinisation
(Carcinisation) Special AffinityCarcinisation is the game’s special crab-like evolution direction. The old one-point-per-unique-choice rule and cap of seven are not certified; the saved Steam achievement requires reaching Carcinisation 10 in a run. Check current tradeoffs in the Codex.
The old draft says each unique evolution adds one Carcinisation level, capped at seven, and ties this to The Crabtain. The saved Steam condition instead requires reaching Carcinisation 10 in a run. Its list names only six examples while calling them seven, and the compulsory single-Affinity route has not been verified. Read the current conditions before planning the run.
- ▸ Pincer + Pistol Pincer + Exoskeleton: Carcinisation concept
- ▸ Shell + Carapace (Imposing): defensive concept (stacking unchecked)
- ▸ More Legs + Sprint: movement concept (interaction unchecked)
Steam Community and the subreddit r/EverythingIsCrab were the original draft’s discussion sources. No measured adoption rates were retained, so these ten examples are not a verified popularity ranking. Use them as entries to inspect in the Codex.
Body Slam
Legendary ImposingEffect: Old description, unchecked: a short-cooldown charge with area knockback scaling with Size/Mass.
Why consider it: The old guide calls Body Slam a universally strongest evolution and claims fully multiplicative Size scaling. These rankings and scaling details are unverified; official 1.1 notes also changed its cooldown.
Alpha
Epic GregariousEffect: Old values, unchecked: ally damage +50%, HP +30%, and two extra ally slots.
Why consider it: The old guide calls Alpha a mandatory Epic that doubles combat strength and is used by almost all speedrunners. No adoption measurement or doubling effect has been verified.
Pollinator
Rare GregariousEffect: Old description, unchecked: automatically Charms small animals in range without a cooldown.
Why consider it: The old guide treats Pollinator as a required Alpha prerequisite and automatic ally generator. These effects and the dependency have not been verified; official 1.1 notes confirm its unlock was changed to 25 points of interest.
Sharpen
Common PredatorEffect: Old values, unchecked: physical critical chance +15% and critical damage +25%.
Why consider it: The old guide presents Sharpen as a universally useful Common critical multiplier, but this has not been verified. Check its actual effect and current damage interactions; official 1.1 notes exclude its bonus from damage-over-time attacks such as poison.
More Mass
Rare ImposingEffect: Size +20%、Physical +15%、Speed -5%。
Why consider it: The old guide links More Mass directly to Body Slam damage and lists Speed −5%. The exact scaling and penalty are unchecked; do not assume the penalty is always easy to offset.
Pincer
Common CarcinisationEffect: Old description, unchecked: a pincer attack adding one Carcinisation level.
Why consider it: The old guide treats Pincer as a Common starting point and compulsory for The Crabtain. Read the current evolution and achievement conditions; no universal requirement is verified here.
Pistol Pincer
Legendary CarcinisationEffect: Old description, unchecked: a powerful ranged pincer shockwave inspired by a pistol shrimp.
Why consider it: The old guide calls Pistol Pincer a Legendary finisher adding one Carcinisation level. Its rarity, exact effect and guaranteed boss advantage have not been independently verified.
Tail Wag
Common GregariousEffect: Old values, unchecked: Charm range +30% and Social +10%.
Why consider it: The old guide treats Tail Wag as a required Common that expands Pollinator and Alpha range. Check those effects and prerequisites in the current Codex rather than assuming them.
Smol
Common PreyEffect: Old values, unchecked: smaller hitbox, Speed +15% and Dodge +10%.
Why consider it: Smol is a Size-related option to inspect. The old promise of dramatic survival gains in every build has not been measured; official 1.1 notes also explain that smaller Size reduces Feeding Distance, Attack Area and Nearby Area nonlinearly.
Wings
Legendary Branching (movement; old classification unchecked)Effect: Old description, unchecked: flight, terrain-damage immunity and partial avoidance of ground attacks.
Why consider it: The old guide says Wings is boss-only and completely nullifies Water, Sand and Snow hazards. These acquisition and immunity claims have not been verified; read its actual terrain effects before relying on it.
The store advertises 125+ evolution-based abilities. The old community draft’s rarity breakdown below has not been reconciled with the current Codex, and updates can add more choices.
| Rarity | Count (legacy; unchecked) | Role |
|---|---|---|
| Common | 35entries | Basic choices; combinations matter |
| Rare | 30entries | Middle-run choices |
| Epic | 11entries | Build direction |
| Legendary | 10entries | Finishing role |
| Branching | ? | Boss/branching category (unchecked) |
| Total | 125+ | Ongoing checks; updates can add content |
The old guide treats Branching as boss-specific choices with an unknown total. This classification has not been verified; official updates discuss Specialisations separately.
🎯 1. Let useful choices clarify your build
The old guide says an Epic at levels 3–5 fixes the build, with Sharpen/Smol as universally safe early choices. Those thresholds and guarantees are unchecked. Judge each choice by its actual effect and your current needs.
⚖️ 2. Keep a coherent direction
Matching choices can make a plan easier to follow, but +10% per level weighting, a two-to-three-pick threshold and the two-main/one-support rule are not verified game restrictions.
🧪 3. Compare rerolls and upgrades throughout the run
The old guide uses levels 1–5 for one-point rerolls, level 6+ for ten-point upgrades and a 5–10 point boss reserve. These figures and a guaranteed Branching reroll are unchecked; use the current screen’s costs.
👹 4. Review food and level-up timing
The old guide recommends withholding food before a boss to chain a Branching choice into a level-up. A guaranteed post-boss Branching reward and that timing advantage have not been verified.
🦀 5. Read Carcinisation’s actual goal and tradeoffs
The old all-seven-or-none rule and claim that taking three or four blocks other Affinities are unverified. Use the current Codex and The Crabtain condition rather than treating that restriction as compulsory.
The tables retain the old guide’s evolution names, rarities, effects, prerequisites and build roles for comparison. Their detailed values and dependencies are unchecked historical entries, not a certified complete Codex. Scroll horizontally on mobile; the first column remains fixed.

All detailed prerequisites and values above are inherited from an unchecked community-based draft and may change with patches. Repeated entries such as Antennae or Shell do not establish that each listed Affinity assignment is current; use the game’s Codex as the final reference.
