Proficiencies: All simple and martial weapons, all light and medium armors, light shields.
Evil Eye: As long as a Blackguard holds nothing in his off-hand he can detect good as a Paladin detects evil, and can use Detect Magic at-will as a spell-like ability, although he only learns the presence of magical effects originating from an Evil source, or with the [Evil] descriptor. While a Blackguard manifests his Evil Eye he has an Evil aura as a Paladin has a good aura.
Cursed Smite: Once per encounter a Blackguard can make a Cursed Smite attack against a foe gaining a bonus to the attack roll equal to his Charisma modifier and bestowing a -2 penalty to the struck foe's attack rolls, damage rolls, skill checks, and ability checks if the attack hits. The foe can make a Will saving throw to remove this penalty at the end of each of it's turns DC 10 + 1/2 Blackguard level + Blackguard's Charisma modifier +1/round effected. Further, any damage dealt to the effected creature (including damage dealt by the Smite itself) can't be healed by any means until the victim makes it's saving throw against the penalty. A Blackguard can make an additional Cursed Smite each encounter every six levels after 1st.
Poison Use: As Assassin.
Invocations: Starting at 2nd level, a Blackguard gains divine invocations drawn from the Warlock's list of invocations. He can gain any Least Invocation at 2nd and 5th levels; any Least or Lesser Invocation at 8th and 11th levels; any Least, Lesser, or Greater Invocation at 14th and 17th levels; and any Least, Lesser, Greater, or Dark Invocation at 20th level. The saving throws against these Invocations are determined by the Blackguard's Charisma modifier. A Blackguard can gain Eldritch Essence Invocations and apply them to any Cursed Smite attacks he makes, but he cannot gain Eldritch Shape Invocations.
Fearless: 2nd level Blackguards are immune to all fear effects.
Blasphemous Defiance: 3rd level Blackguards add their Charisma modifier to saving throws against spells and spell-like abilities, and to saving throws against any effect generated by an Outsider or Deity. Further, they become immune to "divine damage" and take only half damage from divine spells or effects originating from Outsiders or Deities.
Aura of Despair: Starting a 4th level, any foe within 10ft of a Blackguard takes a penalty to saving throws equal to 1+1/2 the Blackguard's Charisma modifier.
Improved Curse: The penalty from a Blackguard's Cursed Smite increases to -4 and he deals an extra 1d6 negative energy damage with the attack if it hits, as well as dealing 1d6 negative energy damage whenever the foe fails its save to remove the penalty.
Aura of Pain: Starting at 9th level, whenever any foe within 10ft of a Blackguard fails a saving throw it becomes nauseated for 1 round.
Mettle: As Hexblade.
Greater Curse: The penalty from a Blackguards Cursed Smite increases to -6 and he deals an extra 2d6 negative energy damage with the attack if it hits, as well as dealing 2d6 negative energy damage whenever the foe fails its save to remove the penalty. This extra damage does not stack with the extra damage from Improved Curse.
Aura of Unluck: Starting at 15th level, whenever any foe within 10ft of a Blackguard makes an attack roll, skill check, or ability check it must roll twice and take the lowest result.
Heart of Darkness: Starting at 16th level a Blackguard is healed by negative energy as well as by positive energy, is immune to gaining negative levels, death effects, and any effect which can be removed by Remove Curse.
Dark Curse: The penalty from a Blackguard's Cursed Smite increases to -8 and he deals an extra 3d6 negative energy damage with the attack if it hits, as well as dealing 3d6 negative energy damage whenever the foe fails its save to remove the penalty. This extra damage does not stack with the extra damage from Improved Curse or Greater Curse.
