Here is a screenshot of the Market for Hero's in Holybread.
The marketplace is sorted by CHEAPEST cost of Hero's.
I have purchased all of these Hero's from the marketplace and released (burned) them.
They no longer exist in game.
REMOVED FROM MARKETPLACE
Another 20 Hero's have been removed from the Marketplace and returned to players inventories.
These Hero's have been on the market for more than 180 days and were not selling due to many different reasons.
If you are still an active player and see that a Hero has been returned to your inventory you are welcome to relist them on the marketplace.
I would advise you to adjust the price to help it sell if you re-list it.
As always thanks for playing
