Recovery from extensive injuries from shielding station fight ch.24:
Ch.26 woke up after sleeping for a week with health at 87% (unchanged in ch.35), reason for lower health not explicitly explained. (An earlier edit had this number at 83%.)
Known relevant information. “Magic always comes at a cost, and the cost of receiving magical healing is that your body needs nourishment.” Selene ch.26
“I managed to fix all of the injuries you received, but it took the entire week to avoid putting too much of a drain on your body while I fully regenerated the damage to your lung and intestines. Organ damage always takes longer to repair properly than something like a broken bone or even a severed limb. your injuries should be fully healed, but if you have any problems like tingling or phantom pains, please let me know. I have quite a bit of experience doing these things so I don’t expect any issues, but it never hurts to be careful” Naiad ch.32. This may or may not fully explain things but Mai has yet to ask about it.
