A non-chaotic character that has trained and meditated for years until they finally unlocked their chi abilities.
As an action, a character with Unlocked Chi may spend 1 of your Hit Dice from your Healing Pool to maximize your Hit Points up to your total possible Hit Points (Hit Die type plus constitution modifier per character level) retaining any damage you may have taken before this action.
Additionally, any fantastic ability provided by your character's racial trait costs 1 Hit Point to activate. In cases of passive abilities like Darkvision or Flight, the effect lasts for 8 hours. In cases of active effects like an Aasimar's Light Bearer or a Changeling's Shapechanger, it costs 1 HP to activate for each usage. In cases of once per long rest abilities Like Healing Hands or Breath Weapon, it costs 1 HP for the 1st use and 2 HP for every use afterwards, until you complete a long rest.
A Monk can spend your Ki points in place of your hit points for Chi Attacks. You must spend any available Ki points first and may use hit points to continue using Ki abilities.
- Chi Detection:
A character with Unlocked Chi may use an attack action to make an Arcana skill check to attempt to detect the presence of chi. A skill check of 10 will reveal powerful chi energies up to 10 feet away. Every 10 feet beyond that is revealed for every additional 5 you roll (DC check of 15 for 20 feet, 20 for 30 feet, 25 for 40 feet, etc). If successful you can spend a bonus action to focus on a single object within that range, and reveal if it is a chi item (weapon, armor, tool, or a deposit of jade or gold), or the current hit points of a chi gung.
- Chi Attack:
A character with Unlocked Chi may spend 1 Hit Point per level to add their Hit Die type of Force Damage, to the damage of an unarmed attack. This must be declared, and the Hit Points spent, before you roll your attack.
- Chi Defense
As a Reaction to an incoming attack, a character with Unlocked Chi may spend 1 hit point to interrupt the attack and add resistance to force damage until the end of your next turn.
This also negates the 5 foot push of a Chi Attack.
