Shackles can now also be cast on allies and Mass Serpent Wards that stay within 2000 units of Shadow Shaman. Allied units are not disabled by Shackle.
Increases the amount of time incoming damage is reduced to 1.5 seconds. When Fowl Play is triggered, Shadow Shaman becomes invulnerable for .1 seconds and 3 additional uncontrollable chickens are created that last for 3 seconds. While Shadow Shaman is transformed, he can now use items.
