This mod started out as a compilation of all those other mods that add new styles to Jade Empire. Eventually I figured out how to add styles myself and added a few more. All in all there's around 40 styles now. 50 if you count weapon upgrades as well. Quite a lot of styles have been modified. Some have been re-balanced. To others I've added new effects. And some have been re-purposed entirely. But I didn't stop at adding and modding styles either. There are new gem armors, new techniques, new merchants, brand new concepts like specializations... I can say without the slightest bit of exaggeration, that this is the largest mod for Jade Empire out there. In fact: It is many times larger than all other mods combined and that is not just because it *contains* so many other mods. The last time I checked the codebase totaled to 25,000 lines. In other words: This mod is a complete overhaul.
The stone armor is one of the new gem armors. This armor attunes you to the Stone Immortal magic style. Enemies who make contact with you, will take magic damage. And you will do considerably more damage with Stone Immortal yourself.
