I was pretty sure that healthgate required 50%+2 of your maximum health, turns out it doesn’t. That said the only source I can find for the +2 thing is the wiki. Was this already known?
50% of 2 is 1, so (50% Max HP) +1 of health when the maximum is 2 equals 2.
Also, take anything on the wiki with a grain (plus 1) of salt.
It makes sense, I’ve just only ever heard +2, not +1. And yeah, video game wikis in general are quite something.
That is a great healthgate setup. out of all the vault hunters, I have difficult setting up Axton and Zero for Healthgate builds.
