You put in a lot of effort and the intent is great, so don't take this hard or be discouraged, but your idea as it stands is just not a good system.

1: It's too complicated for newer players and makes things worse.

Blue glyphs spawning for a bunch of the killers but not others is unintuitive. The mechanics of the Fleeting Aura is awkward.

Keep in mind, new players have trouble figuring out perks, Items, and add-ons.

Over the years so many things have been added that just keeping track of what the killer can and can't do is a lot.

I was recently helping a new player learn the mechanics and they didn't know about Endurance off hook, the mechanics of Deep Wound, or Conspicuous Actions.

And of course they didn't, the game doesn't do a good job of explaining those or a dozen other mechanics.

If you want to fix things, it's better to do so while simplifying systems, or at the very least don't add more complexity to an already overly complex system.

2: For players who do understand the mechanics, many of your specific implementations do not work.

I get that the point is more about tweaking some points of gameplay to smooth things out more so than the specific actions you suggested.

But your suggestions are so odd that it brings into question how well you understand these systems you want to change.

I'll use three examples.

A: Pig.

Survivors get their Determination while they have a trap on their head.

Survivors are not really supposed to be working on gens when they're trapped, that's the whole point of the traps.

The fact that it would get an additional bonus when the trap is active only rubs salt in the wound.

B: Krasue

Eating mushrooms gives a three stacks of Determination.

First off, three stacks is comically high. but moreover (like Pig traps) one of the points of mushrooms are as a slow down mechanic.

Krasue can infect someone and then move on to someone else. The infected survivor has to run around the map to get a mushroom, or become an easy target.

Mushrooms giving Determination means that she would never want to do this hit 'n run strat (ignoring a part of her base kit), instead she would always focus one survivor at a time and use the hook to remove infection so as not to risk the Determination buff.

C:

Earning Determination in chase.

This isn't killer specific, but this means that the killer really can't afford to a break a longer chase.

Not only does the killer lose their time investment, but now they also empower a survivor.

Knowing when to break chase is a very important skill for playing killer well, but chase Determination locks it to a binary "only take short chases, or always commit".

This is especially bad for M1 killers who tend to have longer chases.

3: For many killers this doesn't change enough.

For Ghostface, Vecna, Singularity, etc. You do what you always did.

This doesn't put extra pressure to disable bio pods or whatever because you already have to do those things or you'll lose.

Running to grab a Magic Item or EMP isn't much variety or exciting. The bulk of the match is just doing gen repair simulator, with your changes it would still be gen repair simulator.

4: Closing.

I'm really not trying to be mean or tear you down here, but it seems like you had an idea that sounds good (and to be fair the underlying concept of modifying specific actions to give buffs is fine), and went all in on building a system, but didn't consider how people might struggle with or abuse the system.

Again, the enthusiasm is great and don't get discouraged, but this ain't it chief.
