For each point of mana missing by the target unit, damage is dealt to it and surrounding enemies. The main target is also mini-stunned.
Aghanim's Scepter Upgrade: Increases stun duration. Mana Void kills cause the enemy's highest cooldown ability to take longer to cool down upon respawning.
The stun passes through spell immunity.
Damage is calculated based on the primary target's mana, but applied to all enemies within the area of effect.
