Hi I was wondering if you could change the first perk on my God mode class and how much is it

I was told that you can turn off invincibility and you also can't sprint is this true

Is it possible to have God mode or double health on bo1 with out being invincible because my friend that has a tag is saying it is but people on TTG are saying it's not

Hi I was wondering if this was for xb1 and also if you can chose to only have God mode not God mode with invisible
