Prior to Legion, this spell summoned a guardian to aid you in battle. The Protection and Holy guardians had no weapons, while the Retribution guardian used a sword made of light. During the Cataclysm beta, the weapons equipped by the Guardian of Ancient Kings were:
Holy version now has a cooldown of 3 minutes (down from 5 minutes), and summons a guardian that heals the ally that the Paladin healed for 100% (up from 10%) of the amount healed, but no longer heals nearby friendly targets.
Retribution version now has a reduced cooldown of 3 minutes, down from 5 minutes, and the maximum number of stacks has been reduced to 12.
Hotfix (2013-07-09):Guardian of Ancient Kings (Holy version) should now properly interact with Battle Fatigue. Previously, Battle Fatigue was being incorrectly applied to the ability's subsequent heals.
Patch 5.0.4 (2012-08-28): Now learned at level 75 (was 85).
Patch 4.2.0 (2011-06-28): Uses the new Assist pet stance functionality.
Casting Guardian of Ancient Kings no longer resets the auto-attack swing timer.
The Holy version of Guardian of Ancient Kings will now more reliably heal targets at max range from the paladin.
The Retribution version of Guardian of Ancient Kings now benefits from the paladin's hit and expertise.
Hotfix (2011-01-03):The Strength bonus from the Retribution version of Guardian of Ancient Kings now applies its bonus based on total Strength instead of just base Strength.
