AC Bonus
When unarmored and unencumbered, the monk adds his Wisdom bonus (if any) to his AC and CMD. In addition, a monk gains a +1 bonus to AC and CMD at 4th level. This bonus increases by 1 for every four monk levels thereafter, up to a maximum of +5 at 20th level.
These bonuses to AC apply even against touch attacks or when the monk is flat-footed. He loses these bonuses when he is immobilized or helpless, when he wears any armor, when he carries a shield, or when he carries a medium or heavy load.
Flurry of Blows
At 1st level, a monk can make a flurry of blows as a full-attack action. When making a flurry of blows, the monk can make one additional attack at his highest base attack bonus. This additional attack stacks with the bonus attacks from haste and other similar effects. When using this ability, the monk can make these attacks with any combination of his unarmed strikes and weapons that have the monk special weapon quality. He takes no penalty for using multiple weapons when making a flurry of blows, but he does not gain any additional attacks beyond what’s already granted by the flurry for doing so. (He can still gain additional attacks from a high base attack bonus, from this ability, and from haste and similar effects).
At 11th level, a monk can make an additional attack at his highest base attack bonus whenever he makes a flurry of blows. This stacks with the first attack from this ability and additional attacks from haste and similar effects.
Stunning Fist
At 1st level, the monk gains Stunning Fist as a bonus feat, even if he does not meet the prerequisites.
At 4th level, and every 4 levels thereafter, the monk gains the ability to apply a new condition to the target of his Stunning Fist. This condition replaces stunning the target for 1 round, and a successful saving throw still negates the effect.
At 4th level, the monk can choose to make the target fatigued. At 8th level, he can make the target sickened for 1 minute.
Evasion
At 2nd level, a monk can avoid damage from many area-effect attacks. If a monk succeeds at a Reflex saving throw against an attack that normally deals half damage on a successful save, he instead takes no damage. Evasion can be used only if a monk is wearing light armor or no armor. A helpless monk does not gain the benefit of evasion.
Fast Movement
At 3rd level, a monk gains an enhancement bonus to his land speed, as shown on Table: Monk Unchained. A monk in armor or carrying a medium or heavy load loses this extra speed.
Ki Pool (Su)
At 3rd level, a monk gains a pool of ki points, supernatural energy he can use to accomplish amazing feats. The number of points in a monk’s ki pool is equal to 1/2 his monk level + his Wisdom modifier. As long as he has at least 1 point in his ki pool, he can make a ki strike.
At 3rd level, ki strike allows his unarmed attacks to be treated as magic weapons for the purpose of overcoming damage reduction.
By spending 1 point from his ki pool as a swift action, a monk can make one additional unarmed strike at his highest attack bonus when making a flurry of blows attack. This bonus attack stacks with all bonus attacks gained from flurry of blows, as well as those from haste and similar effects. A monk gains additional powers that consume points from his ki pool as he gains levels.
The ki pool is replenished each morning after 8 hours of rest or meditation; these hours do not need to be consecutive.
Ki Power (Su) Ki Metabolism (Su): A monk with this ability uses his ki to control his metabolism. As long as he has at least 1 point remaining in his ki pool, the monk needs to eat and drink only 1/4 as often as normal, needs only 2 hours of sleep each night (including to replenish his ki pool), and can hold his breath for up to 1 hour per point of Constitution. As a move action, he can spend 1 ki point to enter a state of suspended animation, falling unconscious and appearing dead to all senses. At the time he enters this state, he indicates a preset period of time or a triggering condition, after which he awakens.
Still Mind (Ex)
At 4th level, a monk gains a +2 bonus on saving throws against enchantment spells and effects.
Investiture (Su)
An invested regent gains a pool of investiture points, supernatural energy he can use to call upon amazing abilities and divine protection. The number of points in the invested regent’s investiture pool is equal to 1/2 his monk level + his Charisma modifier. As long as he has at least 1 point in his investiture pool, the invested regent can select one of his saving throws as a swift action and gain a +1 sacred bonus on saving throws of that type for 1 round. If he spends 1 point from his investiture pool during this swift action, he instead gains a sacred bonus equal to his Charisma modifier on the saving throw selected.
A character with this feature and the ki pool class feature tracks investiture points and ki points separately.
