🥇Rank

Monsters can be upgraded once every 10 levels. Upgrading requires the consumption of monsters with three rarities: common/uncommon/rare and a certain amount of $SOCIAL and $SLAND. In different upgrading stages, the required quantity of common/uncommon/rare monsters and the amount of $SOCIAL and $SLAND are different.

Only by upgrading can they be promoted to a higher level and obtain better attributes and computing power.
