Right after Orion defeated the goblin king, the system revealed what he needed to do for his body to be able to absorb miasma.
Currently, not only could Orion absorb miasma with the techniques he had learned, but he could also purify the artifacts that had miasma oozing out of them.
He released a little bit of Astral energy, coating his body and the artifacts as well.
Shrouding his body with astral energy helped to prevent his body from absorbing the miasma in the corrupted artifacts.
Astral energy acted as a divine energy that was capable of purifying corrupted mana.
It flowed into the artifacts, and it didn't take more than a second for the artifacts to begin glowing with a yellow hue.
Before today, Orion had developed the ability to sense and manipulate Astral energy, but he could only control a very small amount of the energy.
