Synergy
Systems based off of: Bleach (soul reaper one, Quincy one and hollow/arrancar one) Attack on Titans (one for titan, one for the scouts that can be used for beginners but still have the flexibility and maneuverability of Spider-Man in citys.) Naruto (each sage and most kage level Characters) One Piece (one for each devil fruit that can be upgraded until awakening) Shield Hero (one for each hero weapon and vassal weapon) Etc.
A.I. chip from Leylin or something similar, give it to the librarian. Will be easy to him upgrade/create spells and others arts, get him to analyze the process of hologram spell and shadow clone. You will get a easy spell to strengthen the sorcerer's. Get some other cultivation of mind/will/soul strengthening system to analyze and distribute to the sorcerer's again to avoid info overload from shadow clone or possible brainwashing from others forces.
