Frequently asked questions
What does the Cube do in Task Bar Hero?
The Cube is where you convert items into other items: synthesis combines nine same-grade items into one higher grade, crafting returns a random item for a chosen gear slot, alchemy melts items down into gold and Cube EXP, offering trades an Anniversary Coin for a random item, and Corrosion (added with the Ver 1.2.0 Plaguelands update) melts items into Contamination for entering the Plaguelands.
How do you level up the Cube in Task Bar Hero?
The Cube gains EXP when you melt items down through alchemy, and its level gates which recipe tiers you can use. This page lists the full EXP formula per grade and level, and the exp-optimizer calculator projects your new Cube level from the items you plan to melt.
