Anduin: Book of Heroes

I made it through the first few books getting stuck only a couple times.

I finally made it to the final boss, Lady Sylvanas.

(Of course, would I have actually won or is it just never ending phases?)

But I digress.

How in the actual eff am I supposed to win? After all of that, she equips a bow that summons immediate lethal.

Because 2 dmg AoE is sooo OP, right?

I had no problem making a few attempts on each boss.

This one? Not so much because it is so annoying and rage inducing to be right there and have to once again, go through her 50 “transformations.”

Any advice would be appreciated.
