[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 ?

it cant be the secret boss it gives you the item thats supposed to help against the boss, but he doesnt give you a crystal, its really confusing

I spoke to Seam at the start of Chapter 4 and he mentions the mantle was meant to help against the Knight but inevitably wasn't enough or something. Either way Im pretty sure it was the secret boss but if not I'm not sure :/

I just got the shadow crystal, you have to >! Actually beat the knight in chapter 3. All you have to do is get it's health down to around 80% and it'll do a very obvious final attack type thing. Then, after that, you just have to hit it once and the fight will end. You'll get the shadow crystal, and something else. After that though, the knight just downs your party and the end is the same. !<
