If you came across this structure and you couldn’t figure out what it does, you simply didn’t meet the condition for it to activate. Or maybe you did, but you didn’t notice its effects!
These blue portal-like stone structures can be found all over the game world, but the game never tells you what they are for or how to use them.
The answer is a lot simpler than you might imagine, though. You simply have to approach them when you’re not at full health.
Do so and the structure will activate; look at your health while standing close to it. These naturally-occurring structures dramatically boost your health regen.
They don’t seem to do anything else as far as we know. The area of effect for this boosted healing is also extremely small, so you basically have to stand right next to it to receive the buff.
Besides, the health regen buff is lost as soon as you get away from the structure.
It’s a good idea to get close if you happen to be gravely hurt and spot one of them nearby. Other than that, they have no other uses.
Nonetheless, at least you nowknow what they are! Whether they’re useful to you or not is another matter.
Venezuelan gamer cursed by being interested by most games, resulting in a ridiculous backlog he’ll never be able to conquer. Been gaming for over two decades now! Few things exemplify his wide variety in gaming tastes as the fact that he’s a big fan of both Souls games and the Atelier series at the same time. Also a big fan of Yakuza/Like a Dragon, Deadly Premonition, Zero Escape, and Dead Rising, among others. Considers Lost Judgment and Sekiro to both be masterpieces.
