Acid rain brackets
Corrosive envBracket = 29. Corrosive + Toxic (14×): sum 43, count 2, envBracket = 42. Humidity-acid combo during Shroomie return defines June 2026 fungal meta.
Acid weather damages path tiles cosmetically — not crop loss.
Shroomified (49×) third tag during double events pushes envBracket toward 90 — equip Shroomie and screenshot spore UI for trade proof.
