Frequently asked questions
What are soulstones used for in Task Bar Hero?
Soulstones upgrade heroes. There are four, one per difficulty tier: the Immortal Soulstone from Normal, then the Nightmare, Hell and Torment versions from their matching difficulties. Which soulstone you need depends on the upgrade you are aiming for.
Where do soulstones drop in Task Bar Hero?
Soulstones come from Act Boss boxes. There are 11 Act Boss boxes in the game, and unlike stage boxes they carry no re-drop cooldown, so the limit on farming them is how fast you can clear the act boss rather than a timer.
How many act boss runs do I need for a soulstone upgrade?
That depends on the drop rate of the box you are farming and how many soulstones the upgrade costs. The calculator takes your target upgrade and works back to the number of runs and the expected time, using the game's own drop tables rather than community estimates.
