Has this challenge become unnecesseraly hard?
This tome challenge was made before Nurse's rework. Now that her blink attacks don't count as basic attacks anymore, the only way I can see this challenge being done is if you have that add-on that disables her blinks, which isn't very good to begin with. Can the devs please change this challenge to be more realistic to Nurse's current state?

Yeah that looks like a big problem, the solution is as simple as changing a few class id's so either Behavior will fix this next patch, or it'll be so insignificant that they'll change it in 5 years.
I’ve done that challenge before. It sounds hard but it’s actually not. Just run the addon that makes you 115% after a lethal blink and you will get the challenge completed.
You think you can get an M1 without blinking again after going through a fatigue and the Survivor getting a speed boost from hit AND doing that in 15 seconds?
I did it and it worked. Just make sure there’s no god loops plus they won’t expect seeing nurse moving at 115%
Yeah, just do this. I got it on my first try like this.
Survivors never expect you to suddenly be able to outrun them.
