LORD OF TERROR
Known in the ancient tongue as Al'Diabolos, the Prime Evil of Terror, the demon lord Diablo seeks to claim the world of Sanctuary for the Burning Hells. As the Lord of Terror, Diablo thrives on the fear of others, only satiated by the horror of those who fall before him. His victims are innumerable, his schemes are unknowable, and his gender is...malleable.
Charge an enemy, dealing moderate damage and stunning them for 0.5 seconds. If the enemy hits an unpathable location, they are stunned for 1 second.
Create a demonic rune under each enemy Hero on the battleground. After a short period the rune explodes dealing heavy damage and stunning for 2 seconds.
