1. USES OF MINE
1) Purpose of Mine
You can get gold continuously from the mine.
2) How to supply Gold
Place the monster you have in the (+) shaped empty slot to collect gold. You can place up to 3 monsters in a single mine to collect Gold.
3) Cooldown Time of Gold Supply
It is shorter as the Star-Rank of the monster placed in the mine is higher.
4) Adding the Mine
You need to add the mine continuously to collect more Gold. You can add the mines via the 'Add Mines' button at the bottom of the list.
2. GROWING THE MINE
1) Level Up
You can raise up the level of the mine by using Gold.
It is the easiest way to grow your monsters, but the Level Up value is reset by Prestige (rebirth). Please be careful.
You can upgrade your mines by using Soul.
