Raknag (Heroic)

Strategy

 * Raknag will cast "circle" spells (i.e., Raknag weaves a ring of red) that form red, gold and blue circles on the ground. Move out of the circles to avoid damage.
 * Stand near the edge of a circle as he casts the next one to cause them to combine into a new colored circle. Combine this with a third cast and all circles will be removed.
 * If you are on the quest Tears of Veeshan: Shattered Dreams, go back to where you found Raknag and collect his spirit by clicking on it for the quest update.
