Corrosion
Corrosion melts 1-9 items into Contamination, the resource that lets you enter the Plaguelands. Exact per-grade values, datamined — no level scaling.
Frequently asked questions
How does Corrosion work in Task Bar Hero?
Corrosion is a Cube recipe added with the Plaguelands update, unlocked at Cube Level 30. You feed it one to nine items just like Alchemy, but instead of gold it returns Contamination — the resource consumed while you are inside the Plaguelands. The amount depends only on each item's grade, not its level.
How much Contamination does an item give in Task Bar Hero?
It is a flat value per grade: a Common item gives 1, a Cosmic item gives 500, with materials on their own lower curve (Common 2, Cosmic 30). Unlike Alchemy gold and Cube EXP, Contamination does not scale with the item's level or gear slot.
What is Plague Fruit for in Task Bar Hero?
Plague Fruit is a material with a low chance to drop inside the Plaguelands. Its only use is being fed into Corrosion, where it converts to Contamination at a much better rate than melting ordinary gear.
