The Ancient Guardian is a boss mob only found within the Labyrinth region of the Ruins. It looks and acts similarly to the Clockwork Rook, but it appears to be an actual creature covered in fur. Since this is a Boss Monster, it has much higher health and hits much harder than a normal mob. When attacking, the Guardian will charge the player similarly to the Clockwork Rook. Up close, however, it will do a quick close-range uppercut with a very small attack delay.

With normal damage modifier characters, it takes 74 hits with a Spear, 60 with a Bat Bat, 50 with a Tentacle Spike, 43 with a Ham Bat and Thulecite Club, 38 with a Dark Sword to be killed. The Ancient Guardian drops 8 Meat, a Guardian's Horn and a large Ornate Chest when killed. This chest can contain various loot, so killing one does not guarantee any specific item. However, as seen on the Ornate Chest page, the chest usually contains a worthy amount of loot.


That the Ancient Guardian spawns in the "labyrinth" and is named "minotaur" in the console means that it is most likely a reference to the Greek mythological story of Theseus and the Minotaur.

The Ancient Guardian does the second most amount of damage standing at 100 damage per hit (less if the player is wearing armour), and it has the fastest running speed out of every single mob in the game. The most amount of damage is done by Bigfoot.

It takes only 2 hits with an Ice Staff to freeze an Ancient Guardian, making it the boss with the lowest amount of charges required to be frozen. This is probably an oversight by the developers as the Rook takes the same amount of hits to be frozen.

The Guardian is the only Boss Mob that doesn't have an Insanity Aura.
