Discretionary Paladin (Pathfinder Archetype)
From D&D Wiki
A Discretionary Paladin knows that discretion is the better part of valor, and that sometimes the light fights best from the shadows. To that end, she trades in all of a Paladin's Auras for stealth.
Weapon and Armor Proficiency: A Discretionary Paladin is not proficient with Medium or Heavy armor. This alters a Paladin's Weapon and Armor Proficiencies.
Class Skills: A Discretionary Paladin adds Bluff, Disable Device, Disguise, and Stealth to her list of class skills, and removes Diplomacy. This alters a Paladin's class skills.
Skill Ranks: A Discretionary Paladin gets 4 plus her Intelligence modifier skill ranks per level. This alters a Paladin's Skill Ranks.
Aura of Mystery: A Discretionary Paladin adds her class level to the DC to determine her alignment. This replaces Aura of Good.
Sneak Attack: At 2nd level, a Discretionary Paladin gains a sneak attack bonus as a Rogue of half her Paladin level. These stack with Rogue levels to determine her total sneak attack bonus. This replaces Spellcasting.
Evasion: At 3rd level, a Discretionary Paladin gets Evasion as the Rogue class feature. This replaces Aura of Courage.
Rogue's Edge: At 5th level and every 5 levels thereafter, a Discretionary Paladin gets Rogue's Edge as an Unchained Rogue. This replaces Aura of Resolve and Aura of Justice.
Holy Defense: At 12th level, a Discretionary Paladin gains a +1 sacred bonus to AC while wearing light armor or no armor. Anything that causes her to lose her Dexterity bonus to AC also causes her to lose this sacred bonus. This bonus increases by 1 for every 2 paladin levels beyond 12th (to a maximum of +5 at 20th level). She also gains DR 5/evil at level 17. This replaces Aura of Faith and Aura of Righteousness.
