Each of Loop Hero's chapters ends with a boss battle that will test a player's build and maybe even their sanity. This is not the end of the story when it comes to bosses in this unique roguelike, though, as there is a secret one that fans can summon. For those players who want to try their hands at defeating one of Loop Hero's most-difficult enemies, this guide will detail exactly how it is unlocked.

To begin, fans that wish to battle the game's secret boss must first complete its second chapter. This means that players will need to topple the Priestess before they even consider summoning the hidden adversary, and indeed that is no small feat. However, fans that spend some time mastering the basics of Loop Hero should ultimately be able to overcome that opponent and move on to the next step.

Specifically, players must now locate a U-shaped section of their loop, as they need to get quite a few overlapping effects on a single tile. While the minimum number of overlapping effects required to unlock the secret boss is currently up for debate, it is confirmed that six of them will be sufficient. Here is a specific setup that can be used to create an acceptable tile, but Loop Hero fans are free to come up with their own configurations if that is their preference:

  • Place a Battlefield, Chrono Crystals, and Vampire Mansion in a row along the exterior of the U.
  • Place a Beacon and Temporal Beacon behind that row.
  • Place an Outpost in the interior of the U.

With the cards in position, players should see blue sparks on the road at the point where all of their effects overlap. They should then use an Oblivion card on the sparks in order to create a Dimension Rift, and the battle with the secret boss will be initiated as soon as the Hero reaches that tile in Loop Hero. At this point all that is left to do is slay the foe, but that may prove to be quite difficult.

Indeed, this hidden boss is no pushover, and fans should come fully prepared if they hope to stand a chance. This means doing things like unlocking more equipment slots in Loop Hero, though even a well-equipped player is certainly not guaranteed victory in the fight. Fortunately, fans can simply summon the enemy and try again on a subsequent run if they need to.

Loop Hero is available now on PC.
