Alright, this is one of those parts of Mashle Academy where the game just expects you to “figure it out”… and if you don’t know what you’re doing, you’ll either get lost or get wiped by the boss over and over.
This guide is going to walk you through it properly—from getting to Hell, all the way to unlocking artifacts, subraces, and fast travel. I’ll explain it like you’re actually doing the run, not just reading steps.
Step 1 — Getting to the Hidden Entrance (Dundra)
First things first, you need to head to Dundra.
Once you’re there:
- Look for a large blocked wall
- Use any explosive or heavy move to break it
Not every move works, so if nothing happens:
- Try stronger abilities
- Or just bring someone who has a good breaking move
Once the wall breaks, that’s your entry point.
Step 2 — Follow the Path (Don’t Rush This Part)
After entering, you’ll go through a long path.
Nothing too complicated here, but:
- Enemies can slow you down
- It’s easy to lose direction if you rush
Just keep following the path forward until you reach a new open area.
Step 3 — Farming Frost Keys (This Is Mandatory)
You’ll eventually reach a zone filled with Valkyries.
This is where progression actually begins.
What you need:
- 4 Frost Keys
How to get them:
- Kill Valkyries
- They drop keys fairly often, but not guaranteed
Stay here until you have all four. Don’t leave early—you’ll just waste time coming back.
Step 4 — Unlocking the Gate (Lever Puzzle)
Once you have 4 keys:
- There are two side rooms (left and right)
- Each room has a lever
What to do:
- Pull both levers
- Then return to the main gate
You can do this solo, but with a friend it’s smoother.
After that:
- Insert all 4 Frost Keys into the keyholes
- Stand in the center circle
You’ll get teleported into the boss fight.
Step 5 — Boss Fight (This Is Where Most Players Fail)
Let’s be real—this boss is not easy.
He has:
- High damage
- Armor
- Multiple attack patterns
- Adds (extra enemies) at certain HP
Boss Attacks You Need to Know
1. Triple Slash Combo
- Easy to avoid
- Just don’t panic
2. Long-Range Slash
- Hard to dodge
- Better to avoid positioning-wise
3. Jump Attack
- Very dangerous
- Often unavoidable unless timed perfectly
4. Summons (Important)
At certain HP:
- Spawns enemies like Minotaur / Wyvern
Priority:
- Don’t ignore them
- Clear them quickly or you’ll get overwhelmed
How to Beat the Boss (Actual Advice)
- Don’t spam attacks blindly
- Learn his timing
- Focus on survival over damage
- Play safer during summon phases
If you rush, you die. Simple as that.
Step 6 — Inferno Key (Your Reward)
After beating the boss, you get:
- Inferno Key
This is your ticket to unlocking everything else.
Step 7 — Entering Hell (Final Area Unlock)
Now this part is important.
- Equip the Inferno Key
- Hold it in your hand
- Go to the door behind the boss room
This will teleport you to Hell.
What You Unlock in Hell
This is where everything pays off.
1. Subraces
- Press N to locate them
- Usually found to the right side near entrance
This is where you unlock new racial abilities and upgrades.
2. Artifact Forge
- Go straight ahead
- You’ll find the forge
This is where you craft artifacts—some of the strongest upgrades in the game.
3. Fast Travel Point
You also unlock:
- A fast travel location
This makes future runs MUCH easier.
Bonus Reward — Crimson Heart (Important)
When you defeat the boss, you also get:
- Crimson Heart
This upgrades your race to V2
Example:
- New abilities
- Visual changes (like halo for angel)
This is a huge power spike that many players overlook.
