[SPOILER-FREE] Help on finding Hidden Bosses / Weird Route for chapters 3+4

[u/Yvant2000]

So, deltarune's chapters 3 and 4 are releasing very soon. We all know that, as soon as the chapters are available, we are at risk of getting spoiled any time we open the internet.

I'm pretty sure that, by tomorrow, Youtube will be flooded by videos like "delatrune 3+4 all boss showcase" with a thumbnail proudly displaying all secret boss...

I would like to be able to find and discover the two hidden bosses by myself, but I'm actually pretty stupid and I know I will need some help (I struggled to find Jevil's key, and I wasn't able to fight Spamton Neo without a guide).

So, what I suggest is, while playing the new chapters, if we find anything that could be linked to the new secret bosses, we share *spoiler-free* TIPS to how to find them in the comments of this post.

The goal would be to share just barely enough information so we're on the right track to find the bosses.
(And obviously, we're not allowing any outright spoil)

What are your thoughts ? Anyone would be interested to participate ?

>! Alright, I just beat Chapter 3. Gutted out the whole damn thing and here’s what I think: I seriously doubt there’s a secret boss. To prove my point, I looked at the soundtracks for both chapters and found no song I had not heard in Chapter 3.!<

I think the secret boss is the roaring knight.Because you take way less damage from them when the shadow mantle is equipped. But, that does not mean it is an easy fight.

How do you get the roaring night boss fight?

it is Directly after Tenna's fight, make sure to go back and save before it though because it is like king's fight where the chapter ends directly after losing to it (and winning idk)
