Your healing spells and their multistrikes also place an absorb shield on your target for 10% of the amount healed lasting 15 sec. Does not trigger from healing caused by Beacon of Light.
Mastery: Illuminated Healing was the Mastery for Holypaladins, improved by the mastery secondary stat. It causes direct heals and their multistrikes cast by the paladins to also grant an absorb shield effect on the target.
If a paladin refreshes an existing copy of their own Illuminated Healing on a target, the new absorption amount will be added into the old absorption amount and the duration will be reset. The total absorption created can never exceed 1/3 of the casting paladin's health.
Patch 5.4.0 (2013-09-10): No longer activates from periodic healing effects.
Hotfix (2013-07-09):Mastery: Illuminated Healing's damage absorption shield should now properly interact with Battle Fatigue on both the initial application and when refreshed. Previously, Battle Fatigue was being incorrectly applied to the damage absorption shield a second time on refresh.

Patch 4.3.0 (2011-11-29): Now also applies to Holy Radiance.
Patch 4.2.0 (2011-06-28): Has been adjusted slightly so that if a paladin refreshes an existing copy of his or her own Illuminated Healing on a target, the new absorption amount will be added into the old absorption amount and the duration will be reset. The total absorption created can never exceed 1/3 of the casting paladin's health.
