Why does a Chinese family care so much about a backwater irrelevant ritual held in Japan that nobody cares about or even keeps records about? 

[quote]The family views mana as chi [/quote]

Qi is od, not mana. As a point of clarification, mana is the greater source, the prana in the environment, whereas od is the lesser source, the prana of living beings.

On what principle does this work? IE, increased natural rate of regeneration, something similar to the Dead Apostle's Curse of Restoration, etc.

Since this is a sustained magecraft analogous to making a Mystic Code, it'll take time to make instead of being an instant cast, just as a heads-up.

[quote]Air Synchronization[/quote]

This will be much less efficient than using a broom where air movement is concerned, as a heads up.

[quote]The spell uses half the normal mana when cast on others. [/quote]

Remove this. It'll actually be harder because the Resistance effect is a thing.

[quote]Three variations of this spell exist: a three-word chant that does a lesser amount of damage, a sentence-long chant that does significant damage and a two-sentence long chant that does more damage again.[/quote]

Three-Count spells in this are treated as C rank, One-Count and Two-Count as D rank.

For what specifically?
