Energy + Attack Damage + Spell Drain = Miracle Energy
Each automatic attack grants you a stack of 'Miracle Energy'. Whenever you cast a spell all stacks are consumed and heal you for (Energy Value / 10) per stack. Whenever you receive a stack you have a chance of (Spell Drain Value)% to receive two stacks instead.
Internal cooldown per stack gain: 0.50 seconds | Maximum stacks: 20
Energy improves this healing. Spell Drain increases the chance.
