Deltarune Chapter 3 All Bosses no hit is very very hard.

The addition of this challenge is the secret boss that you have to no hit which is shadow mantle, it's not that hard to no hit but the patterns are almost all rng and you could have bad rng and get hit so it's a big chokepoint.

Before fighting shadow mantle tho, you have to get S-rank in board 1 and board 2 in order to access to the secret games that you have to beat in order to fight shadow mantle.

So the addition from regular chapter 3 is that you have to no hit sword 1, sword 2, sword 3 and shadow mantle too.

Obv this is not the only hard part of the run since in regular chapter 3 there are other encounters that are hard/annoying like rouxls, shuttah, weather duo, triple pippins.tenna and knight.
