Meet the developers in a hidden boss battle

Jeffrey Parkin (he/him) has been writing video game guides for Polygon for almost seven years. He has learned to love just about every genre of game that exists.

Beyond the four chapter bosses, there are secret, hidden bosses in Loop Hero. These have specific ways to summon them that you wouldn’t stumble onto on your own. We’ve already written about one — the Frog King. The others are representations of Loop Hero’s developers who call themselves the True Creators. Defeating them in battle gives you a secret ending.

Our Loop Hero secret bosses guide will teach you how to summon and defeat them, with notes on card tile placement, the best deck, and the bosses’ stats.

How to summon the secret bosses

To summon Loop Hero’s secret bosses and see the secret ending, you need to create a very specific tile — a dimension rift. There are a couple (complicated) steps involved.

Unlike the image above (learn from our mistakes), try to place your overlapping tile close to the cozy camp at the beginning of the loop. This will make sure you’re well healed and stocked up on healing potions when you face the secret bosses, the True Creators.

Step 1: Overlap six areas of effect

The first step is to overlap the areas of effect of six roadside tiles. These can be either adjacent effects or touching effects (shown on the left side of the image above). You’ll see how a tile interacts with its surroundings when you place it or when you hover over it after it’s placed. It doesn’t matter where you do this along the loop. These tiles don’t have to be along a straight stretch of road — it was just easier to show for the image.

For tiles with touching areas of effect, they’ll have to be placed touching your target tile — tiles 2 and 5 in the image above.

You can place the cards in any order. The cards that will work are listed in the table below.

Loop Hero secret bosses summon cards

Name Area of effect Unlock Notes
Name Area of effect Unlock Notes
Spider cocoon Adjacent - -
Vampire mansion Adjacent - -
Battle field Adjacent - Works as shipwreck
Road lantern Adjacent - -
Bookery Touching Library camp building After 20 exchanges, becomes an abandoned bookery with an adjacent area of effect.
Blood grove Adjacent Field kitchen camp building Works as hungry grove
Outpost Touching War camp camp building -
Chrono crystals Adjacent First lich battle -
Smith's forge Touching Upgrade the smithy camp building

Step 2: Remove the center tile

Once you have six overlapping areas of effect, the center tile will start sparking — you’ll see an animated (but subtle) blue streak popping up off of it.

When you see that, use an oblivion card to remove the sparking, center tile. That will change it into a dimension rift. All that’s left is to wait for your hero to visit that tile.

Secret bosses stats, boss fight, and drops

Since this hidden boss fight is against four boss-ish enemies, each representing one of Loop Hero’s developers, let’s look at what you’re up against first.


Deceiver is the mummy-like boss.

  • Pacifist. Always the first target (will get attacked first) and takes double damage from the warrior class.
  • Grind. Health equals double the number of monsters slain in this save (you can check this by clicking on statistics in your camp).
  • Item lover. -2% health for each empty slot in the camp supply (unlocked by the supply depot camp building).
  • Deadline. +100% attack speed when heal is lower than 20%.


Therandom is the floating, black-shrouded boss with the glowing wounds.

  • Life-loving. Always the first target (will get attacked first) and takes double damage from the necromancer class.
  • Perfectionism. +5 damage for each unoccupied camp tile.
  • Story lover. -1% damage for each unlocked monster article in the encyclopedia (unlocked by the intel center camp building).
  • Useless debate. When health is lower than 60%, causes the entire team to argue for 3 seconds.


Blinch is the masked musician boss.

  • Teamwork. Always the second target in battle.
  • Bunnyhop. Evasion equals double the number of loops in current expedition.
  • Musica universalis. This stat isn’t defined in Blinch’s stat block.
  • Procrastination. 30% chance to skip the attack.


Finlal is the robotic boss.

  • Gullible. Always the first target (will get attacked first) and takes double damage from the rogue class.
  • Speedrun. +1% attack speed for each occupied tile in this expedition.
  • Casual. -25% defense for each chapter completed after the first.
  • Not bug, but feature. When health reaches 1%, either gives up or gets 100% HP and fully heals.

Drops and rewards

Defeating all four of Loop Hero’s secret bosses will earn you a few cards, but no special resources. You will see some dialogue and a secret ending, though.

Best Loop Hero deck to summon the secret bosses

The priority in the deck you bring to the Loop Hero secret bosses fight is roadside cards. Bring as many as you can.

Those roadside cards will take up about half of your deck, so you’ll have to make some cuts in the other groups.

Road cards

We like limiting road cards to just village (unlocked by the gymnasium camp building) and wheat fields. The extra healing and XP they generate make them useful.

Roadside cards

Again, bring as many as you can. We leave off the outpost mostly because we don’t like sharing rewards with the mercenaries.

Landscape cards

Landscape cards are a little more subjective, so bring what you think you’ll get the most use out of. Meadows, rocks/mountains, and forests/thickets (unlocked by the forest camp building) are always useful. If you have room for more, we like the suburbs (unlocked by upgrading the gymnasium camp building) for the extra XP boost.

Desert and sand dunes landscape cards (unlocked by the intel center camp building) are useful for decreasing enemies’ health, but we recommend skipping it since space in your deck is limited. Besides, there are other ways to decrease the secret bosses’ health (more on this below).

Special cards

We recommend only bringing the oblivion card. The maze of memories can be useful if you want to rush into the fight, but we prefer over-preparing.

Best class, equipment, and traits for Loop Hero’s secret bosses

The fight against the True Creators is complicated, with four different bosses that each have their own stats and specializations. That means there’s no good answer for the best class, equipment, or traits. We’ll talk about why below.


Especially since there's a boss that draws the attention of each class — Deceiver for the warrior class, for example — there’s no one class that’s better than the others.

We like the warrior class because they’re straightforward and don’t have to wait for new equipment like the rogue does. Whichever class you choose, beef up their stats with landscape tiles: rock and mountain landscape tiles for extra HP, daily healing from meadows and blooming meadows landscape tiles, and increased attack speed with lots of forest and thicket tiles.


For equipment, there’s similarly no one correct answer — just bring your best items. For the warrior, we like anything that deals damage to all, increases attack speed, or increases evasion and counter.


For traits, unsurprisingly, there’s no wrong answer. Focus on healing, resurrection, defense, and damage like Omicron’s technique or shield of faith instead of resource-focused traits. You’re looking for things to keep you alive and make you better at killing, not gathering resources.

Best camp building and upgrades

Each of Loop Hero’s secret bosses have debuffs related to either loop tiles or camp buildings, and that means there’s preparation back at camp that will make the fight easier.

  • Deceiver’s item lover trait reduces their health for each empty supply slot. The supply mechanic is unlocked when you build the supply depot camp building. You unlock extra slots by building and upgrading multiple mud huts around camp.
  • Therandom’s perfectionism trait increases their damage for each unoccupied camp tile. That means you should build to fill out as much of your camp as you can. When you run out of new buildings to create, build multiple farms, mud huts, forests, and lumberjacks.
  • Therandom’s story lover trait decrease their attack as you unlock more chapters in the encyclopedia. The encyclopedia unlocks when you build the intel center camp building. In the encyclopedia’s entries, you’ll unlock additional lore by spending books of memories resources.
  • Finlal’s casual trait reduces their defense for every chapter you’ve completed — each of the chapter bosses you’ve defeated — so you should save this fight until after chapter 3.

Basically what those stats mean is you’ll want to save this fight for late in the game after you’ve defeated all the bosses and built out your camp with most (if not all) available buildings. Upgrade those buildings as much as you can, since all of the upgrades improve your hero’s stats and continue unlocking new cards.
