Causes X Holy damage to any enemy that strikes a party or raid member within 30 yards. Players may only have one Aura on them per Paladin at any one time.
Retribution looms for those beyond redemption.Template:TCG quote
Retribution Aura is an instant cast aura that surrounds the paladin. If an enemy hits the paladin or a party member that is within 30 yards of the paladin, the attacker will take Holy damage. Like a group version of [Thorns].
[Aura Mastery] will extend the radius of all the Paladin's auras to 40 yards.
[Sanctified Retribution] increases the outgoing damage of all party and raid members affected by Retribution Aura by 3%.
[Swift Retribution] provides 3% casting, ranged and melee attack haste to all party and raid members affected by Retribution Aura.
Tips & Tricks
Retribution Aura is the Aura of choice now for the Retribution Paladin thanks to the major overhaul of the class in lead up to Wrath of the Lich King. Fully talented through [Sanctified Retribution] and [Swift Retribution] all party and raid members receive a 3% increase to all damage dealt and 3% melee, casting and ranged haste.
Retribution Aura is affected by +spell damage.
Retribution Aura can work well for tanks, as it is a permanent costless source of threat. As it works "on-hit", it is especially suitable for multi-mob scenarios, as they will hit a lot for (usually) little damage per hit.
Since there is no resistance to Holy damage, the paladin's enemies will always take full damage (unless they resist it by the base miss chance).
Retribution Aura will not stack with a Balance Druid's [Improved Moonkin Form], ie. if both are present in the raid, only 3% haste will be received by members, not 6%. It is worth remembering that even though the addition haste will be canceled out, the +3% damage is still active. Should you have a second Retribution Paladin specced into [Sanctified Wrath] it may be worth selecting a different aura for the raid.
