So, one of the first things I did in AVWW was to try to see what the result of dying would actually be, by trying to let a character die intentionally, only to find that a health potion was automatically used right at the point of what would have been my first death.
Then to further explore the possibility, I let the health potions run out and then was further sustained by Heal Scrolls.
So after seeing how resilient my character was to silly accidental death, I decided maybe he actually had a future after all (I'm still playing him, yay).
My question is what exactly are the limitations of this auto healing? Is there no chance of death if any consumable heals remain? And also, am I losing out on any efficiency by waiting for it to happen? Is there a reason I should consider using these items manually?
