I did some testing on this talent with my 70 tankadin, and this is what I found:
If you are at or below the normal maxed-out defense skill for your level (ie. you have no defense gear), the heal will not proc and will not trigger the two-minute cooldown debuff.
If you have more than the normal amount of defense, any attack that would have killed you will instead be absorbed. This spell will then heal you for the difference between your current health and the amount given by the following formula (ie. if you are at 100 HP before the killing blow, and the formula gives 300 HP, you will be healed for 200).
The formula is: (amount of "extra" defense skill)*(your max HP)*(0.3 / 140)
If your HP before the killing blow is above the amount given by the formula, the attack will be absorbed but you will not be healed.
The heal can crit for 1.5 times the normal value, but this crit is NOT affected by Touched by the Light.
The heal is not increased by Divinity or Improved Devotion Aura.
Ardent Defender will not prevent or mitigate damage from falling, drowning or Chaos Bolt.
