Weapon and Armor Proficiencies: Arcanopaths are proficient with Monk weapon proficiencies and gains the same advantages
    for using a kama, nunchaku or siangham as does a monk. They are proficient with no armor or shields.

Student of Perfection (Ex): The Arcanopath gains the unarmed attack bonus of a Monk equal to his Cenobite levels + Monk
    levels. If no levels of Monk were ever taken, then they gain the bonus equal to their Cenobite level.

Clap of Deafness (Su): 1/round, but no more than once per level/day, the Arcanopath may declare his intent to attack with this
    ability. If the attack misses, the use is wasted. If he strikes the foe must make a Fortitude save at DC 10+Arcanopath
    level+Arcanopath's Wis modifier or be deafened for one roundin a addition to taking damage. A deafened character has a 20%
    arcane spell failure chance to any spell with a verbal component. In addition, they are -4 on initiative checks and unable to make
    listen checks. Creatures immune to critical hits are immune to this attack.

Chop of Muteness (Su): 1/round, but no more than once per level/day, the Arcanopath may declare his intent to attack with this
    ability. If the attack misses, the use is wasted. If he strikes the foe must make a Fortitude save at DC 10+Arcanopath
    level+Arcanopath's Wis modifier or be mute for 1 round. A mute character may not cast any spell with a verbal component, or use
    any items that require a verbal component (spell completion for scrolls, command words for items, etc.) or communicate verbally.
    Creatures immune to critical hits are immune to this attack.

Strike of Confusion (Su): 1/round, but no more than once per level/day, the Arcanopath may declare his intent to attack with this
    ability. If the attack misses, the use is wasted. If he strikes the foe must make a Fortitude save at DC 10+Arcanopath
    level+Arcanopath's Wis modifier. If the foe fails his save, he has a 50% chance of spell failure when casting any spell for 2d4
    rounds. Unless specified to the contrary, this stacks with any other spell failure chance. Creatures immune to critical hits are immune
    to this attack.

Deflect Spell (Su): As a free action, the Arcanopath may deflect incoming ray or energy missile attacks. (An energy missile is any
    weaponlike spell that produces somethign physical that the spellcaster or the spell effect hurls and must be aimed such as Melf's
    Acid Arrow
. Magic missile doesn't count for it is not aimed.)
The Monk must have one hand free to use this ability. He must
    succeed at a Relfex save at DC 20 (+ any attack bonus the spell may give). If he succeeds, the spell is deflected. He may use this
    
ability at any time.

Ki Strike (Su): The unarmed attacks of a Cenobite are considered enchanted by the listed bonus to determine if they may
    damage a creature with damage reduction. This does not increase attack rolls or damage rolls. This does no stack with the
    standard Monk ability of the same name.

Allseeing Eye (Su): The Monk may see as if affected by a permanent see invisibility spell as if cast by a 5th-level sorcerer.

Slap of Forgetfulness (Su): 1/round, but no more than once per level/day, the Arcanopath may declare his intent to attack with this
    ability. If the attack misses, the use is wasted. If he strikes the foe must make a Fortitude save at DC 10+Arcanopath
    level+Arcanopath's Wis modifier. If the save is failed, in addition to normal damage, the foe loses 1d4 prepared arcane spells or
    unused daily spell slots starting from the highest levels the foe can cast. If the results indicate more spells lost than that level has,
    they are taken from the next lower level. Lost spells and slots may be regained normally. Creatures immune to critical hits are
    immune to this attack.

Empty Hand (Ex): The Monk may make melee attacks against any etheral creature in range normally.

Reflect Spell (Su): Whenever the Arcanopath deflects a spell, he may choose to reflect it back on the caster. When reflected, the
    Arcanopath must make any associated attack roll that the spell requires. He may use this ability a number of times a day equal to his
    Wisdom modifier.

Sundering Strike of Oblivion (Ex): 1/day the Arcanopath may change a successful Slap of Forgetfulness into a sundering strike
    of oblivion. In addition to the damage and the lost spell levels (or uses), the foe completely loses knowledge of those spells (or slot
    uses). The foe may make a Spellcraft check at DC 10+spell level+Arcanopath's Wisdom modifier to regain each one. Failure
    indicates the spell or slot is unavailable until they level up again, at which time they regain all lost spell knowledge (or slot uses) and
    may learn new spells normally.
