They serve as the usual roaming characters. They spawn in groups of 4 health-points-worth every 20 minutes until the amount of 40 is reached. When the town is filled, further Feral Monsters are spawned to a bank and moved from the bank into the town as soon as some of them are tapped by the player. The bank also can't hold more than 40 Feral Monsters.
They yield prize track currencies and have a 10% chance to drop crafting currency for each tap, as seen in the table below.
|Act 1||Act 2||Act 3|
|Prize track rewards||6||10||12|
|Obol Rewards (10% chance)||1||2||4|
