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.
Draconic Might
Any of the scaled fist’s class abilities that make calculations based on her Wisdom (including bonus feats with DCs or uses per day, such as Stunning Fist, but not Wisdom-based skills or Will saving throws) are instead based on her Charisma.
Bonus Feats
A scaled fist adds Dragon Style and Intimidating Prowess to her list of bonus feats at 1st level. At 6th level, she adds Dazzling Display and Dragon Ferocity.
At 10th level, she adds Disheartening Display, Dragon Roar and Shatter Defenses.
This ability modifies bonus feats.
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.
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.
