Raizo's Scroll Fruit VITALITY INSCRIPTIONS could inspire Cherry to create Jade Slips (storing martial methods). She could make a basic【HEALTH SUTRA】helping all peoples nourish their bodies using Celestial Qi & Viscera-Nourishing. The CELESTIAL FLAME could sink into the core of the world & trigger a celestial awakening, creating a unique celestial energy biased towards smithing the body directly rather than Glass Cannoneering.

I am also a bit concerned whether you remember that Franky said "its all up here" in Enies Lobby to indicate he memorized the Pluton blueprints anyway, which is a reason why he doesn't hesitate to destroy them.

Cherry can grow flesh, & fuse anything. So why not grow Franky's flesh to a healthy or SUPER healthy level then fuse it perfectly with his cybernetics?

《Don't let the NIGHTMARES within prevail!》 Gilderoy Lockhart's DADA motto

Defense Against Dark Arts training with 'real' dark creatures and wizards or warriors as enemies. Teacher Of The Century! You could also try encouraging a fusion of magic & martial combat utilizing special weapons.

What if you use legilimency to create a mental gameworld that anybody with a key can join via dream signals: modeled after Dark Souls, but with level ups and attribute points increasing the level of your magic reserves and the (speed, strength, dexterity) buff of your magic. There is also a great plethora of hidden or rewarded spells alongside the in-game items like armor and pets or consumables. There is also a higher likelihood of magic suitable for you based on your mahic-signature and memories to be what you get. Though some bosses have fixed high-level spells if you defeat them. Nightmare memories could be extracted by the gameworld to increase the possibilities\map.

Serious scientific Lucas is keul.

Mindworld is passively growing yeah? Maybe he could also take his mindpeople on expeditions of conquest in the land of dreams every night.
