Waiting in her room for the party to return from their dungeon clear, Shiro started on trying to upgrade her attunements to tier 4. Starting with Astral Ice, since it's her strongest element by far, she furrowed her brows when she noticed that regardless of what she did, she was not able to budge the threshold at all.
'Hmm… maybe it's something to do with how much mana I'm controlling right now?' She mused to herself.
With her links only repaired by 7%, moving large bodies of mana was very difficult unless she wanted to strain her links to the point where they threaten to break.
She had done this several times already and each time she did it, her body would be under intense pain. If not for her great tolerance, she would barely be able to move during those moments.
