Health gain

Health gain is the increase of health. Health gain can be caused by six different mechanics:
 * Healing
 * Health regeneration
 * Life stealing and Life Draining
 * Resurrection
 * Health increase due to an increase in maximum health
 * Direct health gain through skills or effects

Direct health gain
Often, health gain is used to refer specifically to this final category of health gain. When a skill's description refers to health gain, this is the type of health gain it refers to.

Direct health gain is not healing. It is unaffected by healing modifiers and does not trigger skills that trigger on healing (e.g. Scourge Healing). Unlike healing, skills that cause health gain can increase a spirit's health.
