How many downs until death

[Liberty Brew]

Looking everywhere, can't find an answer. Do different difficulties have a different amount of times I can go down before my vision turning darker before eventually dying the next time I go down?

Yes, you get a set amount of Wound(s) represented by the amount of bars the total health pool is split into according to the difficulty.

By default, everyone gets 3, Ogryn always gets +1. When you go to heresy, they -1 from everyone. So 2 and Ogryns 3. Wounds add more. You can see it on your healthbar based off of the divides in it.

Small exception is corruption damage (the purple HP you get) from poxwalkers/pox hounds/beast of nurgle could build up over time to pass one of those lines and take away another down.

Basically, every chunk of your HP filled with purple is 1 less down, and every time you down, your current chunk is filled instantly. If all but 1 of your chunks is purple and you go down again, instant death.

The amount of Segments in your HP bar is how many downs you have, called wounds, higher difficulties take some away
