Hello, I were curious if there are any way to make profession with Mutation added to it. I’m beginning modder so I don’t know if there are any way making this and I tried searching it, but every tutorial I found was about things I can do easily. Sorry for bad English if I wrote something wrong.
Yes. Check out the skater or cop professions. They have a “trait” entry. Mutations are traits too.
And welcome to the forums. Try not to plague-zombify folks. 
Hello again. I have problem with adding ammo to professions. Not like I don’t know how to do it, I’m curious if there any way to make specific number of ammo and not just copy and paste ammo name 5 or more times.
Not to my knowledge: you’re giving ammo-pack items. Haven’t had much time to check recently so could well be wrong though.
