This guide is for players who are trying to find and fight every secret boss in HorrorVale. I will show you exactly how to find the hidden bosses in each act.
HorrorVale Secret Boss Guide
Dr. Napkin explained how to find the location of the secret boss of each act below. Each act has one secret boss, and some of them are really easy to miss.
Act 0: Secret Boss
Act 0 has an easy-to-find secret boss, but I don’t recommend fighting it during Act 0. It’s best to have a full team before challenging these bosses. Here’s how to find it:
- Defeat the paranormal lamp in the house.
- Go to Alice’s room and save your game by using the bed.
- Now, head down to the basement in your house.

And that’s it u’ve found the boss. If you have all the characters from Act 1, this fight should be pretty easy.
Act 1: Secret Boss
The secret boss for Act 1 can only be fought after you finish Act 1. You need to complete Act 1 first, then move through Act 2 until you find Shelby. She will say that the roads are opening. After that, return to Act 1 and find Bonz outside the inn on Boo Boulevard. He will give you a key.
Use this key to open a hidden shed nearby:
- Walk through the hidden path to find the shed, then use the key. This boss can be tough, but if you understand the elements and have a strong team, you should do fine. Once you beat the boss, visit Jiang’s shop—there will be a new item for sale, which you’ll need later.

Act 2: Secret Boss
Act 2’s secret boss requires a bit of work. When Poe moves and lets you enter the caravan, you’ll need to start playing games. Honestly, buying Poekens is easier since the games don’t give you many. You’ll need around 10,000 candies for this.
Once you have 500 Poekens, buy the Mirror Ring and wear it. Enter the room to the right of the prize counter, then walk into the center mirror.

This will take you to a weird version of the carnival. Play games here until you get 4 special Poekens and then buy the gem from the guy at the prize counter. Make sure to save your game before buying it because you won’t be able to save afterward! These games are harder than the normal versions, so be ready.
Act 3: Secret Boss
Act 3 has the coolest secret boss, but it will take some time to unlock it. First, you need to recruit Flynt and Jack. They are easy to recruit, so that part is simple. Once you have them, complete Act 3. After that, go to the Gloomy Basin with Flynt in your team and find all the torches.
If you’re being sent back to the start of the maze, it means you came here too early, and you need to progress further in the game. Use a map to help navigate. Once every torch is lit, swap Flynt for Jack and head to the line of torches. You’ll know it’s the right path when the torches light up as you go. Make sure Jack is in your team because he’s needed for the fight!

Act 4: Secret Boss
The Act 4 secret boss is a bit more straightforward. After beating Act 4, head to the Crew Zone hallway. Go to the far end of the hall where there’s an elevator. Take the elevator down, and you’ll see a bright door.
Now, go to Withering Woods and find Minerva. She’s a pink ghost hanging around one of the graveyards at “Deep Woods C.” Buy the pendant from her, equip it, and go back to the bright door. Now you’re ready to fight the boss.

Final Secret Boss
After Act 4, there’s still one more secret boss. You may have noticed the gems you’ve been collecting from each boss. First, recruit Mizure and do her second quest. This will unlock a weird tomb in the mountains.
At the end of the tomb is a door with four gem slots. Put your gems in, and enter the room. You will find a mask. Equip it, then go to Poe’s caravan. Enter the caravan, and u’re ready to fight the final secret boss!!
