This is so you can survive being scimmed by a bullet in battle. Turn down damage to self at least half or 1/4th before battle.
If you go down in battle, the battle ends, so it is of the upmost importance that you stay ALIVE! So my advice to deal with this is as follows and some tips: First thing you must know is that this mod is more dangerous than any other as not only can zombies maul you but also a single bullet or explosion could be the death of you.(Though if you literal die, which is rare, you can sometimes load back your last save) And this cannot be turned out.
