HarshDeath

This mod tries to bring an alternative death experience. When you die you will respawn with only maximum 2 hearths (configurable) for up to 30 minutes (configurable). There is an expensive rejuvenation potion that can cure this. This mod should be compatible with any other mod that affects your items (like gravestone mods)

Here you see an image of the player being restricted to max four hearts. Luckily they have a rejuvenation potion:
