How to Solve Dreamwalker Puzzle

To solve the Dreamwalker puzzle, interact with the Bubble Tower first to gain a Bubble Charge. Use that charge to walk up the wall furtherest from the Bubble Tower. Interact with the Bubble Tower on the wall and head back to the first one.

Interact with the first Bubble Tower to gain a charge and use it on the wall nearest to the first Bubble Tower. Next, go straight, then turn left, and use the second charge on the wall.

The last charge can be used on the wall to the right, just across the room. Follow the path, and you will be able to get to the chandelier's chain to cut it down and create a hole.

How to Fight Stellaron Hunter: Sam

Before fighting Sam, make sure to bring characters whose elements are Lightning, Quantum, and Imaginary. You'll need to break their Toughness to have an easier time dealing with their mechanics.

At the start of the fight, Sam gains an effect called Weakness Protected, where he cannot lose any Toughness.

Wait for Secondary Combustion

Save your Skill Points and use it only after he enters their Secondary Combustion state. When he enters this state, Sam loses the Weakness Protected effect but gains a significant boost in their attacks at the cost of consuming HP.

Use skills and ultimates to break them out of the Secondary Combustion state. Else, they will keep spamming AoEs. Do note that using skills will damage the user during this state, so bring a healer!

Once their Toughness is broken, all your Skill Points get refilled and you have to deal as much damage to them as possible.

What Happens if You Leave?

Secret Ending Occurs

If you decline Aventurine's invitation and leave The Reverie (Dreamscape) using the door shown above, Black Swan will try to stop you one last time. Selecting the dialogue option "I've decided. I'm leaving this place." will allow you to see the secret ending.

It is safe to do this during your playthrough since you can still normally finish the Trailblaze Mission when logging back into the game!
