They are unique when compared to other berries, as they provide a substantial amount of calories and hydration when eaten.
The real value of these berries is in the +10 health. Placed on your hotbar, you can consume a stack of them quickly to restore your health.
Especially useful as eating black raspberries is instant and does not have an associated animation.
This utility makes them invaluable during fights when you don’t have time to bandage or need to recover a small amount of health without putting away your weapon.
The drawback is the rarity of these berries. They can only be found in food crates, and cannot be grown as they do not yield seeds or clone plants.
So save your black raspberries for when they’re desperately needed.
