Dark Knight Talents

Umbral Arts: At 2nd level,the dark knight gains a repertoire of abilities. At every two levels after second, he can choose an Umbral Art from the list. Some Umbral Arts require the dark knight to use certain abilities. Umbral Arts that require the use of Inner Darkness have an Asterisk next to them. Umbral Arts that require the dark knight to be in Darkside have two Asterisks next to the ability's name. If an Umbral Art references a Fortitude, Reflex, or Will saving throw, the DC of the save is equal to 10 + half the dark knight's level + their Charisma modifier:

This aura is suppressed in any sanctified areas, such as holy churches, famous-spiritually charged landmarks, and in any area affected by a Consecrate spell.
Profane Spite (Su)* Dark Knight 4 With a curse, the Dark Knight silences magics. Whenever the Dark Knight is hit or fails a saving throw against a spell or spell-like ability, he can spend a point of inner darkness to have the source make a Will save. A failure results in the target being Silenced for a number of rounds equal to the dark knight's Charisma modifier. This is a curse effect.
Salt The Earth (Su)* Dark Knight 4 The dark knight summons profane energies to blanket his surroundings. As a standard action, the dark knight can spend 2 points of inner darkness to infect a 30ft diameter circle around himself with shadow energy. This area does not follow the dark knight. Creatures that start their turns in the area must make a Fortitude save. A failure results in taking an amount of shadow damage equal to halve his dark knight level (rounded down) times half his Charisma modifier (minimum of +1). A success negates this damage. This umbral art persists for 1 minute. The dar knight can spend an addition point of inner darkness to designate which creatures are unaffected by this ability at the start of its use. The dark knight is never affected by this ability.

Defilement (Su) None The dark knight can lace his attacks with malicious energy, enervating his foe. Upon selecting this Art, the dark knight chooses two conditions. Whenever the Dark Knight uses Soul Eater, an Umbral art that requires an attack roll, or if he critically hits while in Darkside, he can spend a use of inner darkness as an immediate action to inflict a condition. The dark knight can only inflict one condition on a single foe at a time but can change the condition as a free action, once per turn. The dark knight can choose from the following conditions, each with their own respective saving throw: Blinded(Reflex), Bleed(1d4)(No save), Poisoned(Fort), Staggered(Will), and Burning(Fort). Each condition lasts for a number of rounds equal to his Charisma modifier on a failed save. A success negates the effect.

Blackfire Taint(Su) Blackfire Spark Whenever the dark knight uses Blackfire Spark or any Umbral Art with Blackfire in its name on a creature and deals damage, that creature must make a Will save or receive a -2 penalty to saving throws for 1 round. This penalty increases by 1 for every 6 dark knight levels you possess.
Blackfire Erasure(Su) Blackfire Spark, Blackfire Taint, Dark Knight 6 The energies of blackfire can be used to destroy strands of magic. Wherever the dark knight uses Blackfire Spark or any other abilities that have Blackfire in its name, he can choose to spend one or more points of inner darkness as an immediate action to imbue it with a special power. If a blackfire ability hits a creature within the next round, that creature is the subject of a targeted dispel magic spell using the dark knight's level as the caster level, except that this effect cannot dispel a spell of a level higher than the number of Profanity expended to activate this ability (treat higher-level spells as if they do not exist and apply the dispel attempt to the remaining spells with the highest caster level).

Advanced Umbral Arts Prerequisites Benefits
Profane Impurity (Su) Defilement, Growing Impurity Upon taking this Art, the dark knight can inflict 2 conditions instead of one when he uses Soul Eater, an Umbral Art that requires an attack roll, or critically strikes while in Darkside. In addition, he may choose two of the following conditions to inflict: Paralyze, Exhaustion, Countdown, Slow, Stop, Petrification, Disable, and Bleed(1d8). This Art can be taken more than once. Each subsequent selection of Profane Impurity adds another two conditions to the Dark Knight's Defilement. The Stunned, Stop, and Disable condition only lasts one round, no matter your Charisma modifier.
Black Sky (Su) None The dark knight conjures magic of deepest black, calling meteors of darkness to herald destruction. As a full-round action, the dark knight conjures dark matter to fall in a 80ft-wide, 120ft tall cylinder. Each round, creatures that start their turn in the area must make a Reflex save or take 8d10 damage, half shadow, half bludgeoning. The area is considered difficult terrain after the first round it is conjured and persists for 1 minute. The destructive force of this ability ignores the hardness of any objects, Resistances and immunities a creature may have to shadow damage, and ignores damage reduction. Once Black Sky ends, the dark knight is exhausted and the ability affects any structures, unattended objects, and vegetation. Vegetation and any renewable resources in the area, (that are destroyed) cannot be reproduced, scavenged, or mined until a number of years equal to the dark knight's Hit Dice have passed. The dark knight can only perform this art once per day.
Charon (Su) None The dark knight sacrifices their entire being into slaying one foe.

A success halves this damage but lowers all ability scores by 4. Once this Art is performed, the dark knight dies with only a pile of his ashes left. Nothing short of a Breath of Life, Miracle, Wish, or Full Life can restore him. The caster of these spells must have a caster level equal to the number of hit dice the dark knight possessed before his death. The dark knight must have at least 10 points of Inner darkness to use this ability.
Sacrificial Offering(Su) None The dark knight can take power from allies to enhance his ferocity. The dark knight can entreat an ally within 15ft to sacrifice 10 hit points as an immediate action to gain the benefits of his Soul Eater ability to his next attack. He must make this enhanced attack before the end of his next turn or it is lost. Hit points sacrificed in this way ignore any form of damage reduction and temporary hit points from any source. The ally must be willing to impart this benefit. However, this hit point loss does count toward building a stack of limit break for the ally. The ally may spend an additional 15 hit points to give towards the dark knight's Soul Eater ability. An allied creature cannot assist or transfer hit points that would reduce them to less than 25% of their current hit points. Alternatively, the dark knight can spend 15 hit points to impart the benefits of his Soul Eater ability to an ally's next attack roll. The dark knight is still adherent to the restrictions of how much HP he can spend on Soul Eater as normal. The Dark knight can only use this ability 3 times per day.

This mark functions as the Brand of Tracking spell using the dark knight's level as his caster level. The dark knight can also use his black fire on allied creatures and can choose to deal minimum damage on his Blackfire Arts to bestow the burn mark. This is a Curse effect.
Enrage(Ex) None The closer to death the dark knight gets, the more dangerous he becomes. When the dark knight is below 50% health, he gains a +2 Morale bonus to his Strength score for every 10% closer to 0 hit points he is. This benefit dissipates when he is reduced to 0 hit points or less.

The dark knight can spend a standard action, to cast one of the following spells; Poison, Imperil Dark, Dark Spikes, Stone Touch, Demi, Gravity, and Doom. The dark knight must pay an amount of hit points equal to the base cost of the spell to cast it. Once an hour, when the dark knight used this ability, he can pay only half the base cost (rounded down, minimum of 1) instead of the full cost on the first spell he casts. The dark knight may spend a use of inner darkness to augment the spell, making inner darkness count as the number of MP needed to pay for the active augment(the dark knight cannot augment a spell with an amount hit points or Profanity past his caster level as normal). Lastly, the dark knight uses his dark knight level as his caster level and his Charisma modifier as his casting modifier. The dark knight cannot apply the damage of dark side to any of the damaging spells but increases the DCs of each spell by 2 while in Darkside.
Sunless Night(Su) Black Night When using Black Night, he can spread the benefits to ant allies within 30ft but it lasts for only 1 round. The Dark knight can spend 3 uses of inner darkness to have it last for a number of rounds equal to his Charisma modifier for himself and his allies.
