The Monster Army is a system for the player to donate unwanted Monsters and eggs, accessed through a Keeper right next to the Teleport Crystal in Keepers' Stronghold. Donating a Monster or egg will increase the player's army strength and rewards are given on every milestone.
When you donate a Monster or its egg, you will be given both common loot rewards that the donated Monster would normally drop, plus an amount of gold. For example, donating a Blob will reward you with one Small Potion and one Copper. Any equipment on the Monster will be returned to your inventory.

The order is as follows:
