Passive Ability, applies immeaditely when hero learns skill. Everytime hero attacks enemy, there is chance to heal all nearby alliance and damage all nearby enemies. I want to be GUI and very user friendly to customize, like adding levels on that spell. Things i want to be customised are chance to make this happen(%), damage amount and healing amount(random numbers between X to Y like 100-200) and area of effect(small area which will be affected during effect of spell).
