Gains

From the day Erik had sought refuge in that verdant sanctuary in the middle of the forest, a week had passed. Time seemed to both stand still and rush forward in a paradoxical dance, and he was able to restore his mental and physical strength thanks to the tranquility and isolation of the setting and the rest he was able to get.

Things have been going in a different direction since he obtained those powers five days before. It was a huge shock to learn that Hais' brain crystal power could passively raise intelligence levels.

That was a boon he didn't consider, but that explained how Hais was able to understand so accurately what happened when he killed Logan and the others without having seen anything in the first person.

However, Erik quickly discovered that a passive increase in intelligence wasn't the only thing that brain crystal power did. In fact, he could also create a sort of mana brain that gave him a sort of parallel will, hence the way the system named it as such.
