What i mean pyromancer is i want an ability that when i cast avatar it casts frost nova(damaging nearby enemys) upon activation and deactivation and have it provide defence bonuses and damage bonuses to the caster(like avatar does usually) in percentages.
Truthfully a friend wants to know how to do this and he asked me but i dont know how to either so my first post was his exact request this one is my rewording of it for better understanding=).
