All of those are actually really good. Jade is a good catch, it's something fairly easy to get hold of and yet the group won't have it. I remember reading about taoist shamans who would use miniature replicas of swords as ritual items to combat demons, so they might count as "holy" in the sense that they are faith-based. So, while i won't use the idea as-is, I'll pervert the idea into such a token being an integral part of the binding spell. This is a basic, nowhere near refined version of what I'll probably use...feel free to comment on it!

-1 Cloak of Shadows
-1 Fists: Armed Combat: the warriors may use their fists rating with their swords or spears.
+5 Catch: Terra-cota warriors are physically vulnerable to pure jade. They are immune to all magic except the magic that binds them to their form: earth magic. Finally, each statue has an "animating token" of a small copper sword or spear implanted somewhere on it's outer skin: usually somewhere inconspicuous like the neck right below the armor (which is slightly separated from the skin, thus is reachable). If this token is somehow removed (generally requiring a maneuver versus the warrior's fists rating), the animating spirit stays in the token, useless. When animating larger versions, two or more such tokens may be required; removal of some tokens but not all may cause the creature to act uncontrollably, like a zombie without an artificial heartbeat. (One additional token is required for every 3 points of refresh added to the creature).
Other Weaknesses: As with any spirit bound to a physical construct form, Terra-cota warriors have certain predictable weaknesses. While the sheer physical solidity of the construct body offers some protection, normal running water will drive the spirit back into the token, rendering the form inert, and the body becomes as breakable as anything else made of terra-cota. Anyone who knows the particular name of a spirit (each spirit is bound to a particular token or set of tokens) may exercise the normal advantages of such knowledge. The creatures rely heavily on their ability to sense magic, even sensing the "magical life-force" of pure mortals, and thus may be visually impaired around water or when high powered, area effect magics of any duration are involved. Lastly, Terra-Cota Warriors are not thoughtless beasts, but are ancient spirits of combat contained for eons in their tokens... stories exist of them being delayed or diverted from their tasks by impressive tales of heroism or flashy martial arts displays. These stories, of course, remain unconfirmed.
