Weapon and Armor Proficiency: Monks are proficient with the club, crossbow (light or heavy), dagger, handaxe, javelin, kama, nunchaku, quarterstaff, sai, shortspear, short sword, shuriken, siangham, sling, and spear.
Monks are not proficient with any armor or shields.
When wearing armor, using a shield, or carrying a medium or heavy load, a monk loses his AC bonus, as well as his fast movement and flurry of blows abilities.
AC Bonus (Ex): When unarmored and unencumbered, the monk adds his Wisdom bonus (if any) to his AC and his 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 (Ex): Starting at 1st level, a monk can make a flurry of blows as a full-attack action. When doing so he may make one additional attack using any combination of unarmed strikes or attacks with a special monk weapon (kama, nunchaku, quarterstaff, sai, shuriken, and siangham) as if using the Two-Weapon Fighting feat (even if the monk does not meet the prerequisites for the feat). For the purpose of these attacks, the monk's base attack bonus from his monk class levels is equal to his monk level. For all other purposes, such as qualifying for a feat or a prestige class, the monk uses his normal base attack bonus.
Unarmed Strike: At 1st level, a monk gains Improved Unarmed Strike as a bonus feat. A monk's attacks may be with fist, elbows, knees, and feet. This means that a monk may make unarmed strikes with his hands full. There is no such thing as an off-hand attack for a monk striking unarmed. A monk may thus apply his full Strength bonus on damage rolls for all his unarmed strikes.
Usually a monk's unarmed strikes deal lethal damage, but he can choose to deal nonlethal damage instead with no penalty on his attack roll. He has the same choice to deal lethal or nonlethal damage while grappling.
A monk's unarmed strike is treated as both a manufactured weapon and a natural weapon for the purpose of spells and effects that enhance or improve either manufactured weapons or natural weapons.
Stunning Fist (Ex): 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, he can choose to make the target fatigued. At 8th level, he can make the target sickened for 1 minute. At 12th level, he can make the target staggered for 1d6+1 rounds. At 16th level, he can permanently blind or deafen the target. At 20th level, he can paralyze the target for 1d6+1 rounds. The monk must choose which condition will apply before the attack roll is made. These effects do not stack with themselves (a creature sickened by Stunning Fist cannot become nauseated if hit by Stunning Fist again), but additional hits do increase the duration.
Evasion (Ex): At 2nd level or higher, a monk can avoid damage from many area-effect attacks. If a monk makes a successful 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 (Ex): At 3rd level, a monk gains an enhancement bonus to his land speed, as shown on Table: Monk. A monk in armor or carrying a medium or heavy load loses this extra speed.
Maneuver Training (Ex): At 3rd level, a monk uses his monk level in place of his base attack bonus when calculating his Combat Maneuver Bonus. Base attack bonuses granted from other classes are unaffected and are added normally.
Still Mind (Ex): A monk of 3rd level or higher gains a +2 bonus on saving throws against enchantment spells and effects.
