Critical Healing is a value that represents the increased Healing a given Ability will do when performing a Critical Strike. How often you will deal Critical Healing depends upon the higher of your Spell Critical and Weapon Critical. Critical Healing starts with a base Healing increase of 50%, and is capped at 125%.
There are several ways to increase this:
- Racial and Class passives, such as Feline Ambush.
- The Shadow Mundus Stone.
- Champion Point Slottables, Fighting Finesse.
- Additionally some sets contain Critical Healing as part of the 5 piece bonus such as Order's Wrath or Archer's Mind
