From publisher blurb:
Jadetech: Green Jade is the first in a six-part supplement series for the Jadepunk: Tales From Kausao City roleplaying game.
In this digital supplement, you will find everything you need to outfit your Jianghu hero with Jadetech devices that utilize green jade. You will also learn the history of green jade, how it is refined, and how it is used in daily life throughout the world.
This document includes sample Device Assets, such as the Demalian Green Jade Sword and Green Jade Potion of Toughness, as well as animal companion Allies using chaemerics - a science that studies and exploits the effects of green jade on biological systems.
Jade is at the core of the Jadepunk setting. If you are a fan of Jadepunk, you are not going to want to miss the Jadetech series.
