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.
Three attempts (hearts) available each day. Each Heart is used if you fail/leave battle.
Unlock new Battles by purchasing new Essence Stones in Upgrades.
Strategies
Initial strategy
Spam the bottom line with your summons. The only thing that matters at this point are raw atk/hp stats.
Spikes strategy
Once you unlock Spiked Placement (green essence), it will become your main damage source. You will be using it to clear the path for your summons, that will be much weaker than your opponent's. This also means that mana regeneration becomes extremely important upgrade. You should utilize the Mana Overflow upgrade to build up as much max mana and therefore mana regeneration as possible (utilize your health as a resource that lets you gain mana regen - let a few enemy summons through), before overwhelming your opponent with huge pile of summons that will have mostly clear path thanks to the spikes.
Stone Battles
Base amount of Rows on battlefield - 1, and another one added on next stone after previous.
