What the bands mean
S through D here follow the multiplier on the mutation table. They are not an official rank and they are not a brainrot power list. Event mutations can beat Rainbow on paper and still be unavailable on a normal carpet.
S tier
Player decision Top of the published table. Only useful while the event is actually running.
A tier
Player decision Second on the published table. Same access limit as the other half-hour events.
Player decision Stronger than Cyber on the table. Still an event roll, not a carpet roll.
B tier
Player decision The worked income example uses this 11x. Do not expect it on a normal carpet.
Player decision Pick it over a plain Rainbow only if you also want the Halo chance. The income multiplier alone ties Rainbow.
Player decision Below Divine on the table. Still far above Lava.
C tier
Player decision The first seasonal mutation the article says uses a special texture. Event access only.
Player decision Mid event band. Weaker than the 2026 mutations.
Player decision Keep one if it lands. Do not trade a Cyber or Eclipse away for it on multiplier alone.
Player decision Strong next to Diamond, weak next to 2026 event mutations.
D tier
Player decision A collection and base-skin piece more than a best multiplier.
Player decision Double income is real and still the lowest event multiplier on the current table.
