Rarity tiers

Five tiers. Common honours the original Fantums' pumpkin orange. Each tier above Common gets its own fluro palette. Legendary is split 50/50 between two distinct skins.

The tier table

Tier	Weight	Body palette	Accent
Common	62%	Pumpkin Gold (`#F58A2A` body, brown shadow)	None — pure OG callback
Uncommon	25%	Porcelain	Fluro Blue (`#00B8FF` / `#80E0FF`)
Rare	10%	Porcelain	Fluro Green (`#39FF14` / `#A0FFA0`)
Epic	2%	Porcelain	Fluro Pink (`#FF2D8F` / `#FF7DC0`)
Legendary	1%	Special — see Legendary skins	Void Phantom or Holo Iridescent (50/50)

The 1% Legendary band is split exactly in half between the two locked Legendary skins.

Why Common is pumpkin

The vast majority of the supply (62%) wears the original Fantums of Opera palette. This is deliberate: most mints look like a continuation of the old collection, with the cabaret rebrand reserved for rarer tiers. The narrative tracks: most of the cast came back wearing their old costume; the rarer ones got remade.

The Common palette:

Body         #F58A2A   (the original pumpkin orange)
Body shadow  #A0521C   (warm brown)
Outline      #000000   (classic black)
Mouth/pupils standard, no fluro accent

No fluro hair. No fluro mouth. No fluro pupils. Common Fantums are the warm, friendly, OG-looking ones.

Why the fluros climb

Each tier above Common gets a brighter, louder fluro accent. The progression is intentional — you read the rarity off the saturation before you even read the trait list.

Uncommon (Fluro Blue): cool electric. Reads as "first step into the new aesthetic".
Rare (Fluro Green): toxic-green pop. Reads as "definitely Reborn now".
Epic (Fluro Pink): hot cabaret pink. The signature Reborn colour.
Legendary: drops the regular fluro grammar entirely for the two named skins.

Two-tone ultra-rares

A ~1% slice across every tier above Common rolls as a two-tone. Two-tones use one fluro for hair and a different fluro for cape trim, halo, and mouth.

Six combinations:

Pink × Blue       Pink × Green       Pink × Orange
Blue × Green      Blue × Orange      Green × Orange

Two-tones are tier-orthogonal — you can roll a two-tone Uncommon, a two-tone Rare, a two-tone Epic. (Legendaries don't roll two-tones because they have their own dedicated skins.)

OG stat boost on top

If you mint via the reserved window, the rolled tier is unchanged but the rolled stats get a +5% boost, rounded half up, capped at STAT_MAX_AT_CREATION + 2 = 20. So an OG Common is mechanically slightly stronger than a non-OG Common of the same tier.

How the roll works

Tier is rolled at mint time from the master seed via a SplitMix-seeded xorshift128+ shuffle in Xorshift.sol. The full rarity table is shuffled in the constructor and the resulting hash is committed publicly as initialRarityHash. Anyone can re-derive the shuffle and verify the commitment matches what we deployed.

No leading-zero proof-of-work. No browser-side puzzle. No race conditions. Deterministic, auditable, verifiable.

Trait expectations by tier

Trait rarity should track with the tier (Rare Fantums are more likely to have a full operatic costume than a bare-chassis bandana). The roll table is weighted so:

Tier	Typical trait load
Common	1 prop, simple hat or scarf, no fluro
Uncommon	2 props, faint cyan glow on one
Rare	Full costume, item-glow, fluro accents fully
Epic	Half-replaced costume — cape becomes lightning or holo material
Legendary	Full custom render per skin

Shelved alternatives

Three Legendary palettes were explored and shelved (not shipping):

Molten Gold — body in cabaret gold, mouth cyan. Read as too close to the cape colour.
Fluro Orange — body fluro orange. Read as too close to the OG Common.
Crystal — translucent body. Pretty but hard to render at 32x32.

The two surviving Legendaries are the final pair. See Legendary skins.
