The Boss Fight is the final chapter of Bring Back The Sun on Roblox, and it’s the most involved map in the entire game. You’re looking at a castle siege using a crafted bow, a ten-book sorting puzzle across four bookshelves, a hidden magic word puzzle, and a boss fight at the very end to wrap everything up.

It’s a satisfying finale, but there’s a lot going on — and the book sorting puzzle in particular is surprisingly easy to get lost in if you don’t know exactly which titles go where.

I’ve laid out every step below in order so you can get through the whole thing cleanly.

If you’d rather follow along visually, here’s my full video walkthrough:

Otherwise, keep reading for the complete text guide below.

Full Walkthrough: Bring Back The Sun! BOSS FIGHT

Step 1: Collect the Bow

Right when you spawn in, look around for the bow sitting nearby and pick it up. You’ll need it to get inside the castle, but first you need to craft some arrows to actually use it.

Step 2: Craft the Arrows

To make arrows you need three materials: a rock, a feather, and wood. All three are scattered around the starting area — grab each one and then head to the crafting table to combine them.

Once you craft the arrows, you’ll have five shots to work with. If you miss and run out, you can always come back to the table and craft another batch, so don’t stress too much about accuracy.

Step 3: Read the Color Sequence

Before you start firing, find and read the nearby note or scroll — it gives you the color sequence you need to hit on the castle wall. The order is:

Blue → Purple → Green → Yellow → Red

Memorise that or jot it down, because you need to hit the colored targets on the castle in that exact sequence.

Step 4: Shoot the Castle Colors in Order

Take your bow, aim at the castle, and shoot the colors in the correct order. Blue first, then purple, then green, then yellow, and finally red.

If you miss one or hit the wrong color, don’t panic — you can craft more arrows and continue from wherever the sequence left off. Once all five colors are hit in the right order, the castle door opens.

Head inside.

Step 5: Grab the Instant Bucket and Craft the Tool

Once you’re in the castle, the first thing to do is collect the instant bucket sitting nearby. Then head to the crafting table inside and craft the tool that’s available there.

Step 6: Carve the Idle Key

Look at the picture on the wall — it shows you exactly what the idle key should look like. Head to the nearby table and use the tool to carve the wood into the shape shown in the picture.

You need to replicate the image precisely by selecting the right sections of the wood. Once you’ve matched the picture, the idle key is crafted.

Step 7: Go Upstairs and Unlock the Wizard’s Room

Take the idle key upstairs in the tower and use it to unlock the wizard’s room. Head inside and wait for the cutscene to finish.

Step 8: Find the Button and Ride the Platform

Once the cutscene is done, look under the table in the wizard’s room. There’s a hidden button there — press it, and a moving platform will appear that carries you upstairs.

When you get to the upper floor, take note of the bookshelf layout up here (this is Bookshelf C — more on that in a moment). Then grab the one book sitting on a table up here and head back downstairs.

Step 9: Collect All Ten Books

This is where the big puzzle begins. There are ten books total hidden around the castle, and you need to collect every single one before you can sort them.

Nine of them are on the ground floor — check around the main room, behind the statue, and near the bookshelves. The tenth is the one you already picked up in the tower upstairs.

Take your time and search every corner. It’s easy to miss one or two on the first sweep.

Step 10: Read the Bookshelf Categories

Once you have all ten books, read the clue on the wall on the ground floor. It tells you the genre for each bookshelf. Combined with what the book upstairs said, the full breakdown is:

Bookshelf A = Poetry

Bookshelf B = Historical

Bookshelf C = Fantasy (this one is upstairs)

Bookshelf D = Science Fiction

Step 11: Sort the Books Into the Correct Bookshelves

Now place each book on the correct shelf based on its title and genre. Here’s the complete solution:

Bookshelf A — Poetry: Verses of Midnight, Echoes of Heart

Bookshelf B — Historical: The Fall of Rome, Secrets of Pharaohs

Bookshelf D — Science Fiction: Mars Colony, Neon Horizon, Quantum Paradox

Bookshelf C — Fantasy (upstairs): The remaining books go here. Press the button again to ride the platform upstairs and place them on Bookshelf C.

Once all ten books are correctly placed across all four bookshelves, a key will appear — it spawns on the rock behind the statue downstairs. Head down, grab it, and then ride the platform back upstairs.

Use the key to open the chest on the upper floor. Inside is a magic wand.

Step 12: Find the Magic Word — Harry

You have the wand, but you need a spell to use it. Head back downstairs and look at the boards next to the statues. The text on them is inverted, so you’ll need to read it carefully.

One side reads “Statue of an Old Friend” and the other reads “Statue of Harry.” The word Harry is written in a different color — that’s your signal. Harry is the magic word.

Go to the magic wand and type Harry as the spell word, then click spell. A magic platform will appear in the room.

Step 13: Collect the Potion

Before you head up on the magic platform, grab the potion nearby — you’ll need it for the door ahead. Don’t skip this or you’ll get stuck at the next room.

Step 14: Use the Potion and Find the Final Spells

Ride the magic platform upstairs and use the potion on the door to dissolve it and get inside.

In this final room, you’ll find two more magic spells written on the wall: Ignis and Fulgur.

Use the magic wand and cast these spells. Once you do, the room is complete and the boss fight cutscene begins.

Step 15: The Boss Fight

Sit back and let the cutscene play out — the boss fight triggers automatically after casting the final spells. Defeat the boss to complete the map.

Final Thoughts

The Boss Fight map is a genuinely great finale for Bring Back The Sun. The arrow shooting mechanic is a fresh way to open the castle, the ten-book sorting puzzle is the most substantial puzzle in the whole game, and the magic word hunt gives the ending a satisfying storybook feel.

If there’s one thing to take away from this guide it’s to collect all ten books before you even think about placing any of them. That’s the step that causes the most confusion and the most wasted time. Get all ten first, then sort them in one go.

Good luck with the boss fight, and thanks for following the series all the way through to the end.
