Doesn't show how to beat the boss so not worth much IMHO. Try using Alvandor as he is god-like against these particular enemies. I walked through this chapter with him at Star and level 80. Waiting on energy re-charge so watching videos to see what this chapters boss might be but it seems there are few videos on the boss of this chapter. Unfortunately, the title of this is poor as it has nothing to do with final boss in chapter so ...what good is 3 stars?
