HELP: Sacred Stones Chapter 15

[NSY]

I am stuck badly on this chapter, I keep losing units from Tana to Lute to Cormag and the bosses are insane (both of them), I need serious help to beat this chapter cause I can't bear to go though the same thing again.

Ephraim or Eirika? I can help if you're doing Eirika.

 

[NSY]

Eirika

Eirika

Actually, after looking at it, I've only gotten to 13, so sorry.

Anyone else?
