Fa-Jin (Internal Energy)
By Kuseru

Fa-jin or, commonly, jin is the Japanese pronunciation of the Chinese concept of Fa-jing (or jing). Fa-jing is the concept of explosive internal energy as applied to martial art strikes. It can be likened to the energy of a coiled spring. Force expands outward from the Seika Tanden (or Seika No Itten) in Japanese, the Dantian ('cinnabar field') in Chinese, and is referred to as Svadishthana Chakra in Sanskrit (or Indian culture), also referred to as the One Point (or one's center) in English, a central point located two to four inches below the navel and about an inch inside where Chi is believed to originate. This force strikes the point of impact of the attack and the ground simultaneously and since the ground is effectively an immovable force, the force rebounds back through the body into the attack. This force is applied best in punching strikes, because in kicks you are standing on one leg and it's much harder to maintain the balance, root, and structural alignment necessary for successful implementation of this technique. This technique cannot be used for jumping, flying, or leaping attacks at all, because they rely on mass and momentum for their power. At the first level this ability is taken, the character can add one die of damage to hand strikes, elbow strikes, forearm strikes, and headbutts for the cost of two attacks. At the third level of ability in this power, the powerful strikes cost only one attack. For the sixth level of skill in this power, the character can apply an extra die of damage to basic kick attacks and knee strikes, also kicks which normally do no damage do 1D6 damage, but kick and knee attacks done with this power cost two attacks and the character has no bonuses to Maintain Balance while performing such a kick. With the ninth level of skill in this power, the character's kicks powered by this technique cost only one attack. At the twelfth level of skill in this power, the character has full Maintain Balance bonuses when performing powered kicks. Due to the solid posture performed with this technique, there is a one time bonus of +2 to Maintain Balance.
