Spin a Fem All Mutations: Full Rarity List and Pride Specials

What Mutations Add to Your Fems

Mutations are the second layer of rarity on top of a Fem's base tier, giving each collectible a cosmetic flair and a visible status flex on your plot. When you roll a Fem from any dice, the game rolls a secondary outcome that determines whether the unit comes with a mutation, and which one. The mutation sits next to the Fem's name like a title tag — so a Platinum Fem with a Galaxy mutation is widely regarded as a stronger flex than the same Fem with a plain roll. Community testing on the official Spin a Fem page confirms that mutations are layered on top of the existing 17-rarity ladder rather than replacing it.

For new players, the easiest way to think about mutations is as a "shiny" system. You do not need to do anything special to start collecting them — every roll from Silver upward can drop a mutated Fem, and rerolling is always available. What changes as you progress is how rare the higher-tier outcomes become and how much in-game currency you spend chasing them. According to community data tracked on the Spin a Femboy Wiki, each Fem can only hold one mutation at a time, so every reroll is a full replacement rather than a stacked bonus.

Spin a fem all mutations cover three broad families: the standard cosmetic set that drops from any dice, the event-branded set that arrives with limited-time content, and the Pride specials that sit at the very top. Each family has its own rarity curve, drop-rate window, and the best way to farm it. Before chasing any specific mutation, it helps to understand where your current dice sit on the dice tier list — higher-tier dice raise the odds of mutated drops just as they raise the odds of rarer base Fems.

Spin a Fem Mutation Rarity and Tier List

The mutation rarity system is separate from the Fem rarity system, but the two are tightly linked. A common Fem with a Mythic mutation still shows the mutation tag, and a Mythic Fem with a common mutation can feel underwhelming by comparison. The full spin a fem mutation tier list below is built from community-reported drop rates, the official game's 17-rarity ladder, and observed behavior during the last three Mutation Frenzy windows. Tier placement reflects how often the mutation appears, how much visual flex it carries, and whether it is locked behind an event.

The S-tier mutations are seasonal or ultra-rare, and they are what most veterans flex in their plot loadouts. Pride Rainbow only drops during the Pride event window or during a Pride-tagged Mutation Frenzy, and the same is true for every Sakura, Frost, Cyber, Pirate, Angel, and New Year mutation — they require the matching event dice. This is why the event dice guide is worth reading even if you only care about mutations: without the right dice, the matching mutation is essentially locked out.

Standard mutations like Cosmic, Galaxy, Molten, Emerald, and Holy are the year-round grind. They use the standard dice ladder from Silver to Marble, and the higher your dice tier, the better your odds of landing an S or A outcome. Community data suggests that Marble dice push the top-tier mutation rate noticeably above Diamond, which mirrors the same pattern the base Fem rarity ladder follows.

How Rarity Maps to Spin a Fem Mutation Effects

Spin a fem mutation effects are mostly cosmetic, but they still shape gameplay in two real ways. First, the visual flex of a high-tier mutation makes your plot more impressive to visitors, which is the main social currency in the idle tycoon loop. Second, certain event mutations are tracked on community leaderboards and seasonal reward boards, so a Pride Rainbow or Sakura Bloom carries bragging rights that a base-tier Fem cannot. The table below breaks down what each effect actually does in practice.

The practical takeaway is that effects do not change your cash output or your pet bonuses — a Galaxy mutation does not earn more than a plain roll. What it does is signal rarity, and rarity is how this community measures achievement. If you are building a flex plot to show off rare units, the character collection guide pairs naturally with this mutation list because the most impressive displays combine a high-tier Fem with a high-tier mutation.

Spin a Fem Mutation Reroll Cost and Strategy

Rerolling is the core mutation mechanic. When you roll a mutation you do not want, the game lets you pay a currency cost to reroll a single Fem in the hope of a better outcome. Spin a fem mutation reroll cost scales with two factors: the Fem's base rarity and the current Mutation Frenzy state. A reroll on a common Silver Fem is cheap, while a reroll on a Marble-tier Fem during a Frenzy window can be expensive enough that veterans save rerolls specifically for the units they plan to keep long-term.

The biggest mistake new players make is rerolling every common Fem as soon as they get it. Because reroll cost scales with Fem rarity, burning currency on Silvers is fine for clearing inventory, but it is not where the real flex value lives. The community-recommended pattern is to lock your Marble, Emerald, and event-rarity Fems first, then reroll those last so every spin has the highest possible upside. If you are still building out your base roster, the pet tier list is a more impactful early-game investment than mutation rerolls, because pets affect your cash income directly.

A second strategy is to time rerolls around Mutation Frenzy events. During a Frenzy, the reroll cost on the most expensive tiers is discounted, and the drop rate for top-tier outcomes is boosted for the duration of the event. Holding a stack of high-rarity Fems and rerolling them all during a single Frenzy window is widely considered the most efficient way to land an S-tier mutation without burning through your gem stockpile.

Mutation Frenzy Events and Limited Drops

Mutation Frenzy events are scheduled windows where the game boosts mutation drop rates across the board and often unlocks a seasonal Pride variant. According to community data, Frenzy events run roughly once per month, last 48 to 72 hours, and are announced on the developer's social channels. Spin a fem mutation frenzy event timing matters because the S-tier outcomes — including Pride Rainbow — are realistically only farmable during these windows.

The pattern most veterans follow is simple: stop rerolling high-tier Fems a day or two before the announced Frenzy, stack up your reroll currency, and then spend the entire window rerolling the units that matter. Community testing suggests the discount plus the rate boost together produce a higher mutation hit rate than any other farming method in the game, which is why Frenzy events are treated as the canonical chase window.

Codes also play a supporting role. The developer often drops reroll-focused codes during or just before a Frenzy, and these are tracked on the all-codes page along with the rest of the active code list. Spin a fem mutation from codes is not a reliable long-term strategy, but during a Frenzy it can stack meaningfully on top of the discount, and the free rerolls are essentially free attempts at the top of the tier list.

Pride Mutation Specials Worth Chasing

Pride mutations are the rarest outcome in the entire system. They only appear during the Pride event, which historically runs once per year around June. The Pride set includes Pride Rainbow as the headline aura, plus a small family of supporting variants that share the rainbow color palette. Because Pride is seasonal, missing the window means waiting a full year for the next chance, which is why veterans stockpile high-rarity Fems specifically for the Pride reroll rush.

The exact aura list can shift slightly each Pride window as the developer adds new variants, but the headline mutation — Pride Rainbow — has remained the same across the last two Pride events. If you only have time to chase one Pride outcome, Pride Rainbow is the one to prioritize because it is the most widely recognized flex on community leaderboards.

Building a Mutation-Focused Account

If your long-term goal is to fill your plot with top-tier mutations, the order of operations matters. The community-recommended progression is to secure the best dice first, then build a strong pet roster for income, then start rerolling mutations on the highest-rarity Fems you own. This order matters because your dice tier determines your base mutation rate, and your income determines how many rerolls you can afford during each Frenzy window.

A practical checklist looks like this:

• Roll for the highest base Fem rarity you can reach on the dice ladder before worrying about mutations.

• Save at least 30 percent of your reroll currency for the next Mutation Frenzy window.

• Lock all Marble, Emerald, and event-rarity Fems in a dedicated inventory tab so you do not accidentally reroll them outside a Frenzy.

• Redeem every active code during a Frenzy window, since codes often include reroll boosts.

• Track Pride event dates well in advance and stockpile high-rarity Fems for the Pride reroll rush.

Following this progression keeps your mutation farming efficient and avoids the common trap of rerolling common Fems when your currency would be better spent on dice upgrades or pet slots. The mutation system is designed to reward patience, because the gap between the most common mutation and the rarest is wide enough that random rerolling will almost always underperform a focused Frenzy push.

Frequently Asked Questions

How many Spin a Fem mutations are there in total?

The standard and event families combined include roughly 15 to 20 active mutations at any time, depending on whether a Pride or seasonal event is live. The exact count shifts slightly with each update, but the standard year-round set covers about 8 outcomes and the event set adds another 7 to 12. The Pride set adds 3 to 5 more during its window, which is why spin a fem all mutations lists always look bigger during June.

What is the best way to get a Pride mutation?

The only realistic path is to farm during the Pride event window using Pride dice and a Mutation Frenzy boost. Stockpile Marble and Emerald Fems ahead of time, then reroll them during the Pride Frenzy for the highest odds. Codes dropped during the event often include Pride-tagged reroll boosts, so checking the active code list in advance is worth the time.

Is the mutation reroll cost worth it on common Fems?

Generally no, because the visual flex of a high-tier mutation is most visible on a high-tier Fem. Rerolling common Silvers is fine for clearing inventory or experimenting, but the community-recommended use of reroll currency is on Diamond and above. Saving rerolls for a Frenzy window is even more impactful because of the discount and rate boost stacking.

Can you get mutations from codes?

Codes do not directly grant mutations, but they often include reroll boosts, dice unlocks, and currency that feeds into the mutation farming loop. During a Frenzy, code drops tend to increase, so stacking code rewards with a Frenzy reroll push is the most efficient combo. The active code list is updated regularly, and checking it before any major reroll session is a small habit that pays off.

Do mutations affect cash income?

No, spin a fem mutation effects are purely cosmetic. They do not change your per-Fem cash output, your pet bonuses, or your rebirth multipliers. What they do affect is flex value, leaderboard standing, and seasonal reward tracking, which is why the highest-tier mutations still matter even though they do not boost your raw income.
