please help friends I can`t beat undead

I accept with information:Good combos are:Take heavy loss + Time Back. This is probably the best rage spell on higher difficulties.
Mass Magic Shackle (lv 3 distortion). This stops the necromancers from reviving other units. Very useful.
Glot's armor / Wall / Ice thorns. They are barriers to buy you a turn or two. The most basic armor and wall are the best - as they are the cheapest.
