The Way of the Open Palm is an essence gem which grants a large bonus to Intuition and a moderate bonus to Spirit, while imposing a moderate penalty to Body. As its name suggests, it is exclusive to followers of the Way of the Open Palm. There is no Way of the Closed Fist equivalent, with the gem called Way of the Closed Fist affecting Intimidation instead.
In-game description: "Life brings many challenges, and one must learn to flow and adapt to them, to yield and be firm at the same time, to take the hardships life brings and turn them to one's benefit. Though the open, gentle palm, one changes the course of life gently, and with it, one's destiny."
