Let me help you with some of these.
Chi:
Chi is known as "Body Energy", harnessed from meditation with self, this energy is determined by the level of meditation is done by someone. Most common classes are Monks that managed to harness such a power and use it as a weapon, developed by Pandaren 10.000 years ago, during the Mogu control, Kang, The Fist of First Dawn trained the Pandaren prisoners to rise up against the oppression and fight with their bodies and makeshift weapons from tools of their slavery.
Later on, monks mastered this energy into a new combat style and thus allowing more uses of it, such as healing and protection.
Chi is a self regenerative energy harnessed through meditation.
Chi can be harnessed by anyone, but used by Monks on a greater scale.
Chi is a body energy, thus cannot be blocked by magic shields.
Empowered Chi attacks may pass certain types of armor that block physical attacks, but allowing the same force to pass through it.
Chi is also used to vitalize and heal wounds, extensive healing sessions may fully heal body, mind and soul.
Chi healing is slow, highly skilled Monks can speed it up. (Avoiding mechanics.)
The four wild gods of Pandaria determine the power of the Monk, ranging from "Windwalker" as damage dealers, lightning attacks and swift strikes, "Mistweavers" as healers with soothing misty energy and serenity, "Brewmasters" or more well known as "Black Ox Monks", channeling Chi energy to stagger powerful blows and even dodge some and "Red Crane Monks" which primarily based on Holy and a mix of Chi.
Intense chi meditation can break mind control spells and curses.
Chi cannot be silenced/surpressed/interrupted unless it directly affects the user through stuns or other mental effects.
