Hollow Knight Silksong (mod recommendations)

I installed one that gives me 1000 rosaries when I press f3. I came to the conclusion that being able to buy things was more about grinding than anything else, and I didn't enjoy it.

Technically cheating I guess but I don't think it really makes the game any easier.

I might not be as far (just past act 1), but I haven't felt the need to grind rosaries (yet). A bunch of times I'd be exploring for an hour and notice I have like 500+ rosaries, and then I get them made into strands till I have to spend them. I don't think I've seen anything on sale for more than 800 rosaries, Maybe it's different later in the game but at least in the beginning of the game, it doesn't feel like a chore.
- I suppose my experience may be different than others, I'm at the tail end of Act 3 and I have yet to grind for rosaries or shards. I remember people saying I'd need to do that, and I never have.
My second run through, I knew what I needed to buy vs what I could come back for later.
Didn't need to farm rosaries until the end of Act 2, when it was easy because of the tall bugs outside the gay robot boss room.

There's about 3 different "no double-damage" mods that I've tried, for a boss I just couldn't be assed to try legit, anymore. They all seemed to work, fine.

There was a "respawn outside the boss room, instead of at a bench" mod that I installed for a particular boss (you can probably guess), but I can't really speak about whether it works, cause I happened to beat it on the next try after installing.

There was an "infinite shards" mod I tried, but it didn't work at all, and I didn't see any others, so be wary of that one.

Referring to mods available on Nexus Mods, BTW.

Last Judge or the Bilewater boss?
- Last Judge runback didn't really bother me. Just sprint straight out, with a few properly-timed jumps, and you skip every enemy and reach the boss in about 30 seconds.
  Bilewater was nonsense, even after learning how to run it perfectly. And I LIKE Bilewater, as an area.
Bilewater boss isn't that hard once you realize you can stand in the water and spam ranged attacks at him. The arena fight preceding him is harder.
- Agreed, the fight itself I didn't find too difficult. Just the runback. And I got REALLY good at the runback.

Are there even mods and where are they?

Yes, there is actually quite a few so far! Check out https://thunderstore.io/c/hollow-knight-silksong/?ordering=top-rated
There is another popular mod hosting website too, which may have more options to choose from, but I hesitate to recommend it due to the general controversy I've seen as of late.
- Is it a nexus of sorts?

Relaxed mod. Sorry.

It's moddable?

Yes it is, check out my other comment for the link 👍

Only thing I've been running personally has been Reno DX, to add HDR while not departing from the original look. Nice to cleanup all the colour banding on the dynamic lights in dark areas, such as the constant spotlight on Hornet. And yes, it works just fine through Proton, although I had to install it with a prepped zip file from some Reddit thread.

Here's my last judge fight if you want to see the results (note that YT only offers HDR output on HDR compatible displays).

To make it playable for normal people.
- Is it really that bad? I don't really play metroidvanias, but thought I'd give it a try and have really being enjoying it. You have to go in with the expectation that a lot of fights might take 5-10 tries to learn all the mechanics and build muscle memory. It's a hard game, but also very rewarding when you progress precisely because it doesn't spoon-feed you victories.
  Also, IIRC, they've already released a few patches to tone down the difficulty in some of the tougher spots.
~~Come on now, it's fine to be opinionated on the matter but inciting an unnecessary argument doesn't do any good.~~ Mods are a great feature and allow many people to get even more enjoyment out of an incredible game.
- I think my comment might have come across the wrong way. I didn't mean to incite any arguments with it.
  I just didn't expect Silksong to have any mods a month in.
If it's too hard?
I'm not far enough in Silksong to give an opinion, but: Had this happen with Stellar Blade. I was playing through, actually started to enjoy the story, and it has a series of about 3 bosses at the end, interspersed with cutscenes (not fought in a row, just progressively harder). And they were awesome - challenging, but awesome. I felt rewarded for recognizing the full combo strings and parrying, as well as recognizing opportunities to get attacks in.
I get to the final boss (the "Take hand" one), and it's a brick wall. Epic and all, but feels like a leap in difficulty for an already-tough game. I keep at it, trying my best, but it gets no easier. It's also an unsatisfying runback after often barely getting far into the fight. Finally, having not needed it all game, I switch to the game's built-in easy mode. Even then, it's a challenge, and I lose if I'm not paying attention to the attacks! But, I can at least recover from those failures, and try to learn more in one go. From then, I'm eventually able to get through and see the conclusion to the story. I recognize I do not hold bragging rights to that final boss, and I'm fine with that. I liked getting to see the ending cutscene, I exhibited as much patience as I could give with the bosses...but any more than that, and I would've started to hate the game.
I’d like to have a mod where I could play through the game as the knight and use the bad system from the first game. Just as a way to play it again for fun.
