what are task bar heros stone for

In Task Bar Hero , “stone” usually refers to a Soulstone , which is used as an entry key to challenge an Act Boss and progress to the next stage or difficulty. It is not just a normal crafting material; in the game’s progression, it gates boss access and the reward chest you get after a successful clear.

What it’s for

• Lets you start the Act Boss fight for the matching difficulty level.

• Is consumed only when you successfully clear the boss; if you fail, you keep it.

• Unlocks progression to the next Act or higher difficulty after the boss is beaten.

Difficulty tiers

Soulstones are tied to difficulty, with separate tiers for different modes:

• Immortal Grade = Normal.
• Arcana Grade = Nightmare.
• Beyond Grade = Hell.
• Celestial Grade = Torment.

If you meant regular “Stone”

There is also a plain Stone material in some Task Bar Hero guides, and that one is used for crafting gear like helmets, armor, gloves, and boots, or for cube crafting.

TL;DR

If you meant Soulstone , it’s a boss-entry item and progression key. If you meant Stone , it’s a crafting material for equipment and related systems.
