For those who didn't peruse the Reddit AMAA:
It's not exactly what I wanted, but it is still pretty cool. Kind of wish you got more Aura of Despair uses per day as you leveled. Mostly, though, I hope you get Poison Weapon from level 1, to help with that pesky Mage at the Friendly Arm Inn!
Well, a quick run down of the Blackguard is as follows:
Must be evil.
Immune to level drain and fear.
Can specialize in any weapon (2 slots)
Can use any armor, wear any armor
Absorb Health (Level 1) ability to heal self quickly: Absorbs 2hp from enemy per level of Blackguard. Save vs Magic.
Can Turn Undead (Rebuke) as Paladin of same level.
Can use poison weapon 1x every 5 levels.
Can use Aura of Despair. Once per day ability that varies with level: 2nd: Gives enemies -1 to hit, -1 to damage, +2 AC 6th: Gives enemies -2 to hit, -2 to damage, +2 to AC 15th: Gives enemies -4 to hit, -4 to damage, +4 to AC, causes Fear in enemies level 8 or below. 20th: Gives enemies -4 to hit, -4 to damage, +4 to AC, causes Fear in enemies level 18 or below.
