Help Alexstrasza try to kill Deathwing. Protect the five Lifebinder Stones that surround the circle!
Alexstrasza has been preparing this site for many years. Once Deathwing is lured into this circle, she will use the rejuvenating powers of its life energy to overwhelm and destroy him.
It is important that the five lifebinder stones that surround this circle remain uncorrupted during the fight. Deathwing will be concentrating solely on the Queen of Dragons herself; you may escape his notice. Kill any of his minions that try to corrupt the circle.
Talk to me when you are ready to begin!
