The Soulknife class is available online here. (External link)
I am a weapon, forged by aeons. Immortal, deadly, and dangerous, my powers are born from eternity and capable of slaying even immortals. Like time itself, I am inescapable.
Weapon and Armor Proficiency: Epoch-walkers are proficient with simple weapons, light armor, and their own mind blade (regardless of form). In addition, if this is his first level in any class, he may select a martial tradition of his choice.
This modifies the soulknife’s normal weapon and armor proficiencies.
Blended Training: From 1st level on, the epoch-walker gains a talent each time he gains a class level. This talent may be spent on either magic talents or combat talents. The epoch-walker is considered a Low-Caster, gains 2 bonus magic talents at 1st level as normal for gaining his first level in a casting class, and uses Wisdom as his casting and practitioner ability modifier.
This replaces the bonus feat normally gained at 1st level, and the blade skills gained at 4th, 8th, 12th, and 16th level.
Spell Pool: At first level, the epoch-walker gains a small reservoir of magical energy he can use to create truly wondrous effects, called a spell pool. This pool contains a number of points equal to his level + his Wisdom modifier (minimum 1). This pool replenishes once per day after roughly 8 hours of rest.
Time Magic: The epoch-walker gains the Time sphere as a bonus talent at 1st level; if the epoch-walker already possesses this talent from another source, he may instead take any Time talent he qualifies for.
Inevitable Strike (Su): Beginning at 3rd level, the epoch-walker can charge his mind blade with temporal energy as a move action. This effect grants the soulknife a circumstance bonus on his next attack roll equal to half his class level (minimum 1). When the soulknife successfully damages an opponent with this attack, or by touching an ally as a standard action, he creates a link to them that lasts for 1 day per class level and allows him know their current location as long as they are on the same plane and within 1 mile per class level the soulknife possesses. As long as the bond created by inevitable strike is in effect and he can use it to sense the target’s location, the soulknife can target the affected creature with alter time effects regardless of range, line of sight, or line of effect. The soulknife can only have a total number of inevitable strike bonds active equal to his Wisdom modifier (minimum 1); if the soulknife creates an inevitable strike bond against a creature that would increase his total number of bonds beyond this limitation, he must choose a bond to dismiss. The soulknife may dismiss an inevitable strike bond as a free action.
This replaces psychic strike.
Epoch Walker (Su): At 20th level, the epoch-walker becomes immortal. He remains in his current age category forever, though effects that decrease his age or reverse the negative effects of aging can still affect him if he so chooses. Even if the soulknife comes to a violent end, he is spontaneously returned to life (as though by the Resurrection advanced talent from the Life sphere) 24 hours later in a place of his choosing within 20 miles of the place he died. The soulknife must have visited the place in which he returns back to life at least once. In addition, whenever the soulknife forms an inevitable strike bond, it lasts indefinitely, only ending when the soulknife dismisses it or the target of the bond is slain.
This replaces the blade skill normally gained at 20th level.
