Changes

'''{{Anchor|Dark Blow}} ([[SRD:Special Abilities Overview#Supernatural|Su]]):''' The Gate Knight knows that his life means power. By injuring himself, he gains strength. As part of an attack , a Gate Knight can take 1 hp lethal damage which bypasses all DR to himself up to a number of hit points equal to his class level, and in turn gain a bonus equal to twice that amount on weapon damage rolls on the attack. For example, a level 15 Gate Knight can subtract 15 hp and deal +30 damage.

'''{{Anchor|Sacrifice}} ([[SRD:Special Abilities Overview#Spell-Like|Sp]]):''' The Gate Knight learns a number of spell-like rituals which he may employ at will. They function similar similarly to warlock invocations (Complete Arcane) with a caster level equal to his gate knight level, except that they have no somatic components. Each sacrifice requires a sacrifice of his own hit points. The sacrifices come in two forms: sacrifices which deal their damage instantly, which can be healed later (such as a blast of dark energy that takes 4 hit points away from its user); and sacrifices which are constant, subtracting from imposing a penalty on the Gate Knight's maximum hit points until that particular ability is no longer in use.

A Gate Knight gains a sacrifice at 1stlevel, another at 2ndlevel, and an additional sacrifice at every even level. At first , he may only select a least sacrifice. Beginning at level 6, he may select least or lesser sacrifices. At level 12, he may select least, lesser, or greater sacrifices, and finally , at 18th level , he may begin selecting dark sacrifices. When a sacrifice requires a saving throw, it is [[Wisdom]]-based.

Upon reaching 6th level, and at every 6 gate knight levels after that (12th, 18th, and so on), a gate can choose to learn a new sacrifice in place of one he already knows. In effect, the gate knight "loses" the old sacrifice in exchange for the new one. The new sacrifice’s grade (least, lesser, greater, or dark) must be the same as that of the sacrifice being exchanged, and it must be at least one grade lower than the highest-level sacrifice the gate knight can cast. A gate knight may swap only a single sacrifice at any given level, and must choose whether or not to swap the sacrifice at the same time that he gains a new sacrifice known for the level. In epic play, at level 24 a gate knight may even swap out for dark sacrificesfrom level 24 onwards.

'''{{Anchor|[[Endurance]]}}:''' At 3rd level , a Gate Knight's toughness grants him the [[Endurance]] feat.

'''{{Anchor|Dark Burst}} ([[SRD:Special Abilities Overview#Supernatural|Su]]):''' At 4th level , a Gate Knight learns how to take the power of his dark blow and put it into an explosive burst of negative energy. Once per day, he may use a Dark Blow and cause the extra damage damage from Dark Blow to explode outward and deal damage to all creatures within a 20 ft. radius burst of the gate knight as negative energy, in addition to dealing the normal damage to the target. All creatures caught in the area are entitled to a Will save for half damage, at a DC of 10 + 1/2 class level + [[Wis]] modifier. The Gate Knight is unaffected, but his target takes both the damage from dark blow and the damage from dark burst. A Gate Knight can exclude a number of targets (such as allies) up to their his/her [[Wisdom]] modifier if they he/she so choosechooses. If the Gate Knight misses with this attack, the dark burst still goes off as normal. Every 4 levels , the Gate Knight may perform this an additional time per day.

'''{{Anchor|Death Sight}} ([[SRD:Special Abilities Overview#Supernatural|Su]]):''' At 5th level , the Gate Knight is so used to observing the flow of life and death within himself that he becomes aware of the lives of others. He gains the constant effects of a [[SRD:Deathwatch|Deathwatch]] spell.

'''{{Anchor|[[SRD:Diehard|Diehard]]}}:''' At 5th level , a Gate Knight's toughness grants him the [[SRD:Diehard|Diehard]] feat.

'''{{Anchor|Durability}} ([[SRD:Special Abilities Overview#Extraordinary|Ex]]):''' At 7th level , a Gate Knight's self-injuries have granted him considerable durability against harm. He gains his class level as DR against nonlethal damage. For example, a 13th level Gate Knight has DR 13/lethal. In addition, when at negative hit points but not dead, a gate knight may take a full round worth of actions, as opposed to the single actions permitted by the Die Hard Diehard feat. Doing so reduces the gate knight 's hp by 2 hit points (such as if you performed two move actions). As normal for Die HardDiehard, the gate knight dies when he reaches -10.

'''{{Anchor|Mettle}} ([[SRD:Special Abilities Overview#Extraordinary|Ex]]):''' At 9th level , a Gate Knight's determination allows him to shrug off magical effects that would otherwise harm him. If a Gate Knight make makes a successfully successful Will or Fortitude save that would normally reduce the spell’s effect (such as a spell with entry Will partial or Fortitude half) , he instead negates the effects.

'''{{Anchor|Gate of Darkness}} ([[SRD:Special Abilities Overview#Supernatural|Su]]):''' At 11th level, the Gate Knight has been channeling the darkness for so long that his Gate is stained black. When injured by any piercing or slashing attack by a non-reach melee weapon, the Gate which sprays forth is baneful to the living, dealing 1d6 points of negative energy damage. A Gate Knight can toggle this ability on or off as a swift action, but cannot perform a dark burst or sacrifice ability while this ability is so suppressed.

'''{{Anchor|Dancing At The Edge Of Death}} ([[SRD:Special Abilities Overview#Extraordinary|Ex]]):''' At 13th level , it has become apparent that the hole within is not unlike a channel to the power of death itself. As such , when the Gate Knight actually perishes and is later resurrected, he does not lose a level when doing so , as he is so accustomed to the experience.

'''{{Anchor|Deny Death}} ([[SRD:Special Abilities Overview#Supernatural|Su]]):''' At 15th level , the Gate Knight comes under the effects of a constant [[SRD:Death Ward|Death Ward]] spell with a caster level equal to his class level.

'''{{Anchor|Death Throes}} ([[SRD:Special Abilities Overview#Supernatural|Su]]):''' At 17th level, when a Gate Knight perishes, he can choose to go out in a blaze of negative energy. He explodes in a black pulse which destroys his body completely, and deals 2d6 points of negative energy damage per Hit Die to all creatures in a 30 ft. burst, with a Reflex save for half. The save DC is 10 + 1/2 class level + [[Con]] modifier. The Gate Knight's slayer, if within range, is not entitled to a save. If it is unclear which single creature is responsible for the gate knight's death, the designation is up to DM discreationdiscretion.

'''{{Anchor|Undying Rage}} ([[SRD:Special Abilities Overview#Extraordinary|Ex]]):''' At 19th level , the Gate Knight uses his connection to the darkness to continue his existence when he would have otherwise perished. When reduced to negative hit points, he may make a Fortitude save at a DC equal to 10 - his hit points. Success means that he may act normally. He still accrues damage from taking strenuous actions while at negative hit points, but he may continue to fight as long as he can continue to make the Fortitude save every round. It does not protect him from effects which destroy the body, such as [[SRD:Disintegrate|Disintegrate]] or Vorpal, or instant death effects. In addition, when in an Undying Rage , the Gate Knight gains a +8 bonus to [[Str]].

'''{{Anchor|One With Darkness}}:''' At 20th level , the Gate Knight has an awakening and finally reaches out to his inner darkness. Upon realizing its true nature, the Gate Knight transforms and becomes an Outsider (Native). He may still be raised and resurrected, and counts as a member of his original race for all effects. He gains either damage reduction 10/silver or damage reduction 10/cold iron, chosen by the gate knight upon acquiring this ability. In addition , he experiences a subtle physical change to his body which marks him as unnatural, such as blackened eyes or a visible aura.
