If you look at the difference in experience needed to increase Essence between what the Solars and the Terrestrials and the difference in the size of their Essence Pools for instance Solars have Essence x 3 in their Personal Essence Pool, Terrestrials have Essence; Solars have Peripheral Essence of Essence x 7, Terrestrials have Essence x 4. That should give you an indication of the difference Essence to Essence between Celestial and Terrestrial Martial Arts Charms. Also Terrestrial Charms would require less Essence because Terrestrials have smaller Essence pools. So for Celestial Exalted they're more like tricks.

    Jade artefacts, armour in particular needn't be plain objects but could resemble creatures that live in the region of Creation where it's Elemental Pole is. I thought of the idea from the cover of The Sea Watch. The man's armour looked like a crab beastman. I thought why make jade as plain as just being elemental which makes it rather dull. Wavecleaver Daiklaves made from water jade that's turquoise and looks like shallow blue water are cool, but basing artefacts on living things would make them so much more interesting. This would go with ideas about making Lunars more orientated towards the Wyld rather than just animals, although Terrestrial Exalted wouldn't have the power to transform themselves, although they could call on an animal's characteristics. For example a crablike suit of water jade power armour would give them great strength and protection.
   Terrestrial Martial Arts also seemed very dull. I think they should be solid rather than boring. For instance they could include animal styles, or at least versions of animal styles but replicating the immediate traits of an animal such as reproducing it's movements. My version of Snake Style with fighting chains to mimic and snake's coils and tiger claws to mimic it's bite would be a good example. Celestial Styles are something deeper. Something about actually becoming like the subject of the style, not just physically but inside. It's not just about changing their bodies but their minds and Essences. In Sidereal Martial Arts instead of trying to change themselves into something, they try to absorb something into themselves.

    Celestial Martial Arts styles aren't simply ways of fighting, they are methods of understanding, paths of meditating on the subject of the style. Whereas Terrestrial martial arts replicate specific effects Celestial martial arts styles are more figurative and involve progressive understanding of what inspires the style. Once having mastered a Celestial martial art a martial artist can embody the aspect of the style as much as what bears it's name. Many in the martial arts society believe Celestial styles, particularly the ones based on animals were created by Lunars as they repliate the Lunars' practice of embodying and transforming themselves into another being.
   The difference between Celestial Styles ad Sidereal Styles is that where Celestial Styles use the martial art to understand the subject of the art, Sidereal styles use the subject to understand the martial art.
   If Sidereal Martial Arts integrate Creation as a facet of the style, what are the other facets of it?

   9/4 Celestial styles are ways of understanding the subject. Sidereal styles use understanding of the subject to learn the martial art. Or perhaps in a Celestial martial art they transform themselves by learning what the style represents but in Sidereal martial arts they transform themselves by making what the subject represents part of them.
