Crystal Mutation Grow a Garden

Crystal is the prismatic event mutation from crystal rain—55× environmental, stackable, and aimed at short crystallizing precipitation windows rather than everyday drizzle.

How to trigger

mutations.ts: crystalline formation from rare crystal rain events. weather.ts Crystal Rain lists Crystal, Rainbow, and Radiant. Use that weather name; do not invent average event lengths or pet-required crystal procs.

Stacking rules

Crystal is event-category, stackable. Value uses growth × [1 + (sum env − count)]. Solo Crystal → 55. Crystal + Aurora (52×) → sum 107, count 2 → 106. Crystal + Celestial → sum 175, count 2 → 174. Additive bracket only. Rainbow may appear as Crystal Rain’s growth-capable bonus while Crystal stays environmental. No Crystal conflict pairs listed.

Crystal value by weight

Crystal applies a 55× multiplier in the event bracket. The table below shows the value it adds to a reference crop (base 50) across common harvest weights, so you can gauge how much this tag is worth before chasing it.

Crystal value impact

Crystal Rain’s three named bonuses

Crystal Rain documents Crystal, Rainbow, and Radiant together. Rainbow is growth-category in mutations.ts; if it procs, it claims the exclusive growth slot. Crystal and Radiant are environmental contributors to the same harvest when present.

Radiant at its listed multiplier pads the env sum beside Crystal. Counting both icons, subtract two in the bracket formula. Claiming Crystal “multiplies Radiant” misstates formulas.ts.

Cosmic overlap without schedule fiction

Aurora Borealis and Meteor Shower can put Aurora or Celestial on crops in other windows. If a later crystal rain adds Crystal, the harvest may show mixed cosmic-crystal icons—still one env bracket, one growth factor.

Petrified is a thematic related slug for crystalline looks, not a documented Crystal Rain bonus. Link for readers; do not assume auto-stack. Confirm every icon before computing 1 + (sum − count).

Common questions

Can pets create Crystal without Crystal Rain?
mutations.ts ties Crystal to crystal rain events. No pet trigger is listed for this id—unlike Burnt’s fire-pet path or Enchanted’s Kitsune path.
Does Crystal conflict with Glitched?
mutation-conflicts.ts does not list Crystal against Glitched. Glitched is separately marked non-stackable in mutations.ts; follow that flag and current icons rather than invented admin rules.
