A wiki de Build A Ring Farm que faz a conta por você.

Update 5 (Carnival) spray-only mutation. Applied with the Carnival Spray — a Rare single-use drop from Spray Crates (~0.5%) earned via Carnival Pass Tier 11 or Carnival Crate spins, not sold in the Gear Shop. Reported at 9–9.5x across sources (Pro Game Guides 9.5x; Sportskeeda/SportsRant 9x).

Update 4 spray-only mutation. Applies a 9x multiplier via Bubblegum Spray from the Gear Shop.

Elite 8x multiplier. Added in Update 3. Spray-only — no weather event triggers it. Also obtainable from Composter or Plant Rush shop (25,000 tokens).

Update 9 Fourth of July mutation. Applied by the Liberty Spray from Uncle Sam quests 2 and 4, or by the Bald Eagle pet at 2.5% every 600 seconds. The spray was limited to the event week, but the pet keeps producing Liberty afterwards.

Second-highest multiplier. Event-only from the Queen Bee event (0.5% per plant roll).

Update 9 event mutation. Rains down on your farm at random while a Magic Crystal blessing is active during the Wizard Event. Per-plant roll chance is not published.

Event-only mutation from Meteor Shower weather. Per-plant roll chance is not published; the wiki lists it as unknown rather than zero.

Premium 5x multiplier. Galaxy events are rare (4%) so most players buy the spray at $1T.

Limited event mutation available during Build A Ring Farm admin-abuse sessions, which run weekly from the Saturday update. Cannot be upgraded by pets.

Event-only 4x mutation from the Trucker/Mega Farm event. Cannot be bought in the Gear Shop — apply it instantly with a Trucker Spray, an exclusive A/S/S+ grade reward from the Trucker NPC.

Pet-applied mutation from the limited Divine Starfall Griffin. Unlike standard mutations, Starfall stacks on top of an existing one — additively, so Fire plus Starfall is 14x rather than 40x.

Event-only mutation. Cannot be purchased. Triggers during Alien Invasion events.

Triples crop value. Best target after Void for mid-to-late game scaling.

Pet-applied mutation from the Plant Rush Golem. Like Starfall, it stacks additively on top of an existing mutation instead of replacing it, so a Fire plant that picks up Vine sells at 13x.

Major milestone mutation. The jump from Wet to Void is one of the best value upgrades in the game.

Doubles harvest value. Triggers during Autumn weather events.

Mid-tier boost from Blizzard events. Pairs well with mid-rarity Epic crops.

Entry-level boost. Cheap, frequent, and the most practical first mutation for early-game farms.
