This is not very clear and needs to be spelled out fully.Force Wave Slash (Su): A Vorpal Warrior may take a penalty on attack rolls to attack at a range at a rate of -1 to 5 ft of range. She may not take a penalty greater than -5 for this ability.
Force Wave Slash (Su): As a standard action, a vorpal warrior's weapon can be wielded to damage to an opponent beyond her normal range. By taking a penalty to her attack roll (from -1 to -5), she gains the ability to target an opponent at a range of 5 feet per point of penalty to a maximum of 25 feet. The damage her weapon normally inflicts becomes force damage instead of slashing damage. A successful Fortitude save (DC is 10 + 1/2 the vorpal warrior's HD + Cha modifier) halves the damage.
Cut The Air seems rather pointless. How do you judge the attack against a save? You need a mechanic for this. I recommend removing this and letting the vw save normally or give her a +1 competence bonus to Reflex saves if she is holding a slashing weapon.Cut The Air (Ex): Instead of making a Reflex save, a vorpal warrior can choose to make an attack roll with a slashing weapon and use the result instead. If a Vorpal Warrior's attack, succeeds, she avoids the effect as if she had evasion. (This would manifest as slashing a fireball away or jamming a sword into a wall before falling through a pit.)
Cut The Air (Ex): A vorpal warrior gains a +1 competence bonus to Reflex saves as long as she is holding a slashing weapon.
I think it needs proofreading.Unceasing Blood Fountain: The critical multiplier of and slashing weapon wielded by a Vorpal Warrior is increased by one.
