Holy Cause is a passive Crusader skill, unlocked at level 27. The healing issued from dealing Holy damage is not considered Life on Hit (all healing received from Holy Cause will not be shown on the character screen). As such, it will be wise to expect varying amounts of healing depending on the attack's Proc Coefficient and number of enemies hit. Damage bonus is added to the respective stat, and can be used to counter the negative effects of Heavenly Strength.
