How do you defeat cynder

The first stage in the Cynder boss battle is relatively easy. Her attacks aren't that hard to dodge and the 3 spirit gems can keep you alive. In the Portal of Convexity, Cynder's attacks are still easy to avoid, but do a little more damage. If you get far away from her, she lunges at you. The spirit gems are more spread out as well. Once her life bar is orange, she occasionaly flies up and breathes fire, which is avoided by staying to the outside of the platform you two are on. Cynder may also breath fire when on the ground as well. When she is "in the red", DON'T start firing away with your new Ancestral Breath. Instead, space the ray shots out a bit. When her life is gone, you will have full fury. Press R2, and it'll be all over.
