The big, dirty secret is that I've actually written a lot of Exalted conversions. Here is one people actually wanted to see on RPG.net.
Exalted of the Wulin
All Exalted splats are created using a Loresheet. For an example, let me show you Solars.
All techniques and Secret Arts can be used out of combat. If they do, you don't recover spent Chi until next scene. If a combat starts this scene, tough luck for you!
In a combat, the Exalted mobilise all their powers, but out of it, they're not as focused. They were created to be living weapons, the martial artists that can topple the Primordials - and they excelled in this.
It's governance afterwards where they turned out to suck mightily...
Castes are renamed: Dawn is Warrior (duh!). Eclipse is Courtier. Zenith is Priest. Twilight is Predictionist. And of course, Night is Doctor. Yeah, doctor - who else would be better at sneaking and poisoning, not to mention using nerve strikes? There's a reason why Ebon Shadow relies heavily on that.
Anima banners give you away, unless you're a Night that pays 2 Chi at the start of every round. Zeniths can use 1 Chi per a zombie to send their souls to reincarnation. For 1 Chi, Dawns can deal 1 more Ripple to crowds and Lesser Legends. And Eclipses can create a free Major Passion Hypoactivity, based on Predictionism, which states you get -10 on everything until (atonement condition set by the GM) happens, if you break a Vow.
The difficulty to remove it is 150! So, basically, ain't going to happen, barring extraordinarily circumstances.
The Great Curse is gone! What PC needs mechanical incentives to act like an obsessed demigod in a world of cutout figures? (Yeah, I'm joking, but not much).
Well, almost: designate an Orthodox Virtue. Each time you get a Deed in its Selfish counterpart, apply the limit breaks that corresponds most closely!
All PCs starting as Celestials get a free 15 pts of Entanglement, as per the rules, and a 10 points extra that they can only use on this Loresheet. They have to buy it (well, only the Solars, of course).
Solaroid Exaltation (5 pts)
0: You get a free +20 to all Skill rolls related to your Caste, as well as to combat*. This counts as a Loresheet bonus, so it stacks with everything.
5: Status: Lawgivers (with spirits that recognise it, mostly).
-5: Enemy of the Immaculate order, the Bronze Faction and pretty much everyone in the setting.
5 Flaw: You can have the Hunted by the Wyld Hunt disadvantage! It can be free if it's your first or second disadvantage.
2: Lunar ally: you've found your Lunar Mate! What can he or she tell you about yourself?
2: Technique: the Lunar can teach you the Eight-limbed demon god technique, allowing you to use your Unarmed with Paired.
-2: Your Lunar Mate is suspicious of Solars, knowing the stories of what has happened in the First Age. Apply a +5 bonus to their attempts to resist your suggestions.
-3: ...and he or she knows them first-hand. Apply a +10 Bonus to their attempts. And they're at least 1 Rank above you, more likely 2 Ranks. Did you hurt them way back when? That's determined by whoever purchased you this Deed.
3: Gold Faction allies: they will provide you with training!
3 Technique: Palm knows no distance - combine Unarmed and Ranged.
-2: They will also instil into you a respect for them. Get a Paired Passion/Inspiration condition: You get a +5 when following the advice of Viziers, but a -5 when acting against it.
5: Achievement: You have attracted the attention of a Deathlord, who wants you as an ally - maybe even as a non-Abyssal ally.
Alternatively, you could have them chasing you in order to make you an Abyssal, but that would be a Disadvantage.
10: Achievement: You have learned to master your Essence! Add 1 point of Enlightened Chi.
*Non-Solaroid Celestials would get a +15, DBs would get a +10, and Spirit-Blooded and heroic mortals would get a +5 to the same.
...And so on, and so forth. I can write this Loresheet until it becomes longer than some systems, but that's not the point. I'm sure individual Wulin Sages can and will add to it!
