Blade Maiden

Two blade maidens face a vicious aberrant armorlord.

There exists a sect of women from all over the world, headed by the elderly and guarded by the young. This sect is a society of warrior maidens that employ weapons invented by the original founders of this sect. The blade maidens of old desired to be one with their weapons, and did so by bolting the weapons right to their bones, through their flesh. Countless centuries these warrior maidens continued to prosper, working as assassins, mercenaries and guardians of cults and churches to strange gods. In combat, it is known that the blade maidens have a specialty, one that allows them to slash and remove the extremities of their foes.
It is only rumored, but it said by some that these blade maidens (or blade witches as some know them) and masters of twisted armors are vicious rivals. Many battles between the aberrant armorlords and the blade maidens have been seen, but rare few spectators survive such terrible battles to tell the tale.

Weapon and Armor proficiencies: Blade maidens are proficient with the blades granted to them by this class, but gain no additional proficiencies with weapons, armor or shields.

Maneuvers: At each even numbered level, a blade maiden gains new maneuvers known from the Diamond Mind, Oncoming Storm or Tiger Claw disciplines. You must meet a maneuver's prerequisite to learn it. You add your full blade maiden levels to your initiator level to determine your total initiator level and your highest-level maneuvers known.
At levels 2nd, 5th and 8th, you gain additional maneuvers readied per day.

Stances: At 3rd and 8th levels, you learn a new martial stance from the Diamond Mind, Oncoming Storm or Tiger Claw disciplines. You must meet the stances prerequisites to learn it.

Blades of the Maiden (Ex): Upon entering this class, the blade maidens receive a special gift by their elder blade maidens; a pair of blades bolted directly to the bones of their arms. These weapons are of masterful design and perfect for combat, but is a closely guarded secret of the blade maiden sect. These weapons have a base damage of 1d8, deal slashing damage, have a critical range and modifier of 18-20/x2 and count as light weapons for the purposes of two-weapon fighting and are masterwork quality, gaining a +1 enhancement bonus to attack rolls and making them capable of being magically enhanced.
Additionally, they gain benefits as offensive or defensive based on how they are wielded. If wielded defensively, they are typically clasped to their arms, parallel to them and held up like a shield. This grants them a +4 shield bonus to their armor class when fighting defensively, but they are no longer treated as light for the purposes of two-weapon fighting. If they are wielded as offensively, they are held outward in a way almost like an agressive mantis. This reduces the penalties from two-weapon fighting to +0, but reduces their armor class by 2.
It is impossible to remove the blades from the maiden's body without removing their arms or wrists, but they can be folded back against their arms so that their hands may be free to do other things.
The blades of the maiden are considered to be preferred weapons of the Diamond Mind, Oncoming Storm and Tiger Claw disciplines.

Tendon Severing Strike (Ex): At 3rd level, the blade maiden learns a particularly cruel maneuver designed to slice and destroy muscles and tendons, though generally in a way that proves more or less nonlethal. This is treated just as a normal martial maneuver: you must ready it and expend it normally. It is an 4th level strike, and does not belong to any discipline. When you initiate this maneuver, you strike a single foe as a standard action. If your attack succeeds, they are dealt an additional 4d6 points of damage as you slash at their tendons and for every 10 points of damage you deal they are dealt 1 point of Strength damage. This strength damage can never exceed one quarter of your initiator level. This maneuver can only be used with your blades of the maiden.

Bloody Counterstrike (Ex): At 4th level, you learn a special counter that lets an enemy's weight and strength be used against them in a vicious way. This is treated just as a normal martial maneuver: you must ready it and expend it normally. It is an 5th level counter, and does not belong to any discipline. Whenever a foe attacks you with any sort of melee attack and are within your threatened square, you may hold up your blade and strike them with their own force. They are dealt 1d8+their Strength modifier+their Constitution modifier(if any) in slashing damage as they throw themself at your sword. For every size category larger they are than you, they take an additional 4 damage, and for every size category smaller they are than you they take -4 to this damage. This attack only works if their attack is successful against you, but the damage you deal is dealt before they can deal their own. This counter can only be used with your blades of the maiden.

Peel Flesh and Rend Limbs (Ex): At 6th level, you learn what is one of the more disturbing practices of the blade maidens, and that is techniques for removing limbs and peeling off flesh. You take a swift action to lose the benefits of any stance you're in to gain the benefits granted by this stance. While in this stance, you are capable of dealing damage to the limbs of your enemies exclusively, or your attacks can be made against their skin, which allows you to peel it off. To sever the limb of an enemy, you must make an attack against it. The limb's AC is considered to be 10 higher than the target is normally on it's own, but dealing one quarter of the target's hp in damage to the limb will sever it. Damage done to a target's limbs can never bring it below 1 hp.
If you decide to attack the target's skin, you gain a -4 to attack rolls against them as you angle the attacks perfectly. If you aim for their skin and hit, they take full normal damage as well as 1 Cha damage. If you do this, you can also reduce a foe's natural armor bonus(though you can't reduce a bonus granted by magical items or spells) by dealing 10*the natural armor bonus. So if you were to strike them for 20 through 29 damage you could reduce it's natural armor bonus by 2.
While in this stance, any round you make an attack roll in reduces your armor class by an additional -2. You can only use this stance with your blades of the maiden, and only if in an offensive stance with them.

Vicious Slash (Ex): At 7th level, when you strike at the vitals of your foes without memories of the attack, that is if they survive. Whenever you score a critical hit against a creature, instead of rolling for damage, you deal full weapon damage times the critical modifier of your weapon and add a bonus to damage equal to half your initiator level. Additionally, the critical range of your blades increase by 1. This ability only works when wielding the blades of the maiden.

Throat Slitting Prana (Ex): At 9th level, you learn a maneuver that targets the throat of your enemy in an attempt to make them drown in their own blood. This is treated just as a normal martial maneuver: you must ready it and expend it normally. It is an 7th level strike, and does not belong to any discipline. When you initiate this maneuver, you make one melee attack against a single foe at a -4 penalty. If this strike hits, they take 8d6 points of extra damage and must make a Fort save (DC 17+Str modifier). If they fail, they are immediately treated as if drowning. They will continue to do so until their hit points are healed back to full or their bleeding is somehow stopped by other means. If they pass this save they instead are treated as if having a bleeding wound, dealing 1d4 points of damage to them each round until they receive magical healing or the bleeding is stopped some other way. This maneuver can only be used with your blades of the maiden and does not work against creatures immune to critical hits or are in some way immune to bleeding.

Slice Out the Soul (Su): At 10th level, your blades go beyond flesh and bone, beyond the subtle magic of the sublime way and you become capable of dealing out blows to the very essence of your enemies. This is treated just as a normal martial maneuver: you must ready it and expend it normally. It is an 8th level strike, and does not belong to any discipline. When you initiate this maneuver as a standard action, you make one melee attack against a single foe. When it hits, they take 10d8 points of damage and they must make a Will save (DC 18+Cha modifier) or suffer 1d6 Cha drain and 1d6 Con drain as you slash away at their soul. If they pass their save they take only 1 damage to both scores. This maneuver can only be initiated through their blades of the maiden.
