Volcanic Mutation

Volcanic eruption events vein crops with lava lines — 38× env tags that tie into Infernal and Molten endgame heat stacks.

38×eventStackable

How to trigger

Volcanic procs during Volcanic Eruption event weather when lava ash falls on plots. Forge events share heat DNA with Molten procs.

Eruption event ROI

Volcanic envBracket = 38. Volcanic + Infernal (67×): sum 105, count 2, envBracket = 104. Rainbow growth on 2.5 kg crops during eruption week targets leaderboard spots.

Ash weather reduces Pollinated proc — swap bee pets for heat pets during eruption.

Common questions

Volcanic vs Molten?
Both stack — Molten 60× liquid magma tier higher. Eruption enables both sequentially.
Volcanic on ice plots?
Thermal conflict — cold tags drop when eruption heat flags dominate at harvest.
