Shadow Demon

Shadow Demon is a menacing and dangerous intelligence Hero who is most powerful in the early game for his strong set of spells. Disruption will take an enemy out of the fight and make them face themselves, Soul Catcher can curse his victim with vulnerability, and his Shadow Poison can harass any unfortunate foe he encounters. Demonic Purge, his ultimate is his key to a successful kill, he greatly slows down his fleeing victim and removes all buffs of his enemies, crippling and weakening them. His spells also serve as a great support for his allies as well as a great way to gank. With a great start, he can become a strong late game caster.

Tips

 * If you are facing a hero with a strong orb effect like Anti-Mage in the lane, use Disruption on them often and force them to flee from the illusions.
 * Disruption can save you or teammates from incoming damage and spells.
