The tools allow you to mine resources in the world of Gemland.
To start mining resources first you need to learn right profession and then add the right tool in the hero slot. This bundle will allow you to mine the hero's coin and the resource of your choice. Depending on which of these currencies is more important to you, you can choose which of them to mine.
Tools have different rarity. The higher the rarity, the higher the mining multiplier. The rarity of the tool must match the rarity of the hero.
Important mention: When a character withdraws from the game, the learned profession will be burned. You can save the profession only by increasing the rarity of the character.
