Bot will play the game for you, repeating the selected game mode over and over. This produces alot of ingame gold so you will always have enough when legendary hero appears in the shop.
You will have all your cards upgraded and lots of excess gold.
Bot will summon new heroes and merge existing ones.
First select desired game mode. Then check each card slot you want to be upgrades with mana (left to right. leftmost card is 1, rightmost is 5)
You can work or play other games while the bot is running. You can also launch several bots on the same PC.
The game does not need to be on focus, you can cover it with other windows, do work or anything else. Just dont minimize the game.Watch it or leave it, come back after some time and enjoy the spoils. You will become rich and powerful.
