Summoning
From IdleOn MMO Wiki
Create your own Slime army and defeat everyone to become a World Champion.
Slime Battles
Engage in battles against top-tier opponents and earn Chests containing various bonuses.
To start a battle, visit the Summoner's Table in Spirit Village and choose an opponent. Click anywhere on the field to summon your Slimes; each Slime Card requires a random amount of Mana to spawn a Unit, with different Slime types requiring varying amounts of Mana. Your objective is to have your Slimes reach the other end of the battlefield (or the opponent's spawnpoint); each Slime that successfully reaches it will deal -1 HP to the enemy. Keep in mind that the opponent's Units will also attempt to reach your spawnpoint. Think tactically.
Unlock new Battles by purchasing new Essence Stones in Upgrades.
