Visual Effect: A thick white smoke covers the target area and many small white puffs of pipe smoke emerge from the smoke. Once it all clears away Radagast will appear in one of his three forms: Sleigh form, Foot form and Eagle form.
Gameplay Effect: Call and control the Brown Istari for some time. He is a mighty magician but a gentle soul who prefers the company of animals to people. However, he will take up arms and unleash nature's wrath on his enemies if necessary. He can also cast a mighty heal which will regenerate an insane amount of health of any unit caught in the target area.
