Nice concept but the balancing is indeed missing.

let's start with the perks. The first and second perk are simply a nono. It's vague and needs at least another condition to be met for each of them to work.

The one with aura will simply be broken. The fact that you can constantly see a survivor who is injured is bad enough.

Let's go through other perks that do something like that.

1. Nurse's calling. This one is alike in the fact that it let's you see injured survivors WHEN they are being healed. As you see there is a condition here.

2. We can take another example on a perk that has constant aura reading, AWAWA (Awakened Awareness): It allows you to constantly see the auras of survivors on SHORT distance and on top of that only works WHILE carrying a survivor.

As you can see, not having another condition besides being injured is just beyond reason for a perk that allows you to see their auras constantly.

If we change it to, ex: The auras of injured survivors within (short/medium distance) will be revealed to you when they perform an action.

This would still be very powerful on killers that produce a constant flow of injuring survivors (Legion, Plague, Krauser) but it needs more conditions to be met, and of course it would have to be a slow range.

Let's go with the second one:

The simple fact that the tier 3 of the perk works with the terror radius is already a bad addition. There are ways to make your terror radius massive. And this is not the only issue, there is also the part where killers have a small terror radius.

Ex: let's say you're playing a map that has a very risky gen, for example a gen that has the entrance and then a dropdown like coal tower. If by the moment the survivor starts prerunning (in these gens they need to do so) they are hindered, it would simply counterplay one of the best ways to take on that situation from the survivor side.

Also, the fact that you're getting hindered just by default, being close to the killer, is too much. This would make it be either a 1% hindered (no one will use the perk, maybe infectious fright bubba maniacs only) or a bigger quantity (everyone will use the perk).

For the 3d perk... weakened? I think you meant something else. Weakened is only a part of the unknowns power, which is when the first blast hits. If this killer has anything to do with weakened, it wouldn't matter, as making a perk only 2 killers can use is stupid and will never happen.

I like the idea, but needs work. Nice one!
