Wrath-Logo-Small Patch 3.2.0 (04-Aug-2009): Redesigned. Any damage that takes the paladin below 35% health is reduced. This reduction applies only to the portion that pushes the paladin below 35% health (example: a paladin at 50% health takes a 40% hit; the first 15% hits as normal while the next 25% is reduced). In addition, once every 2 minutes an attack that would have killed the paladin will fail to kill, and instead heal the paladin for up to 10/20/30% of maximum health depending on the paladin's defense rating (example: a paladin with defense equal to only 5 times his or her level will receive no healing from the talent, while a paladin who is immune to critical strikes from boss creatures through defense will receive the maximum amount).

Ну а третий пункт ТСа можно просто проигнорить, раз уж нет инфы как именно это (не)срабатывало на лайве
