i hate tried a lot and i always fail, i tried different units and using the magic shield to avoid the artyllery fire but still i cannot beat the level, help ?
I spamed boar riders and protected the one at the front with the Neutral Zone spell as they artillery bombardment usually targets the unit at the front.
First, equip your army with all five boar riders, and smoke bomb.
When battle starts, don't do anything. Just add base archers until you have full 5. Store up lots of gold. Repair your base if needed.
When you have enough gold (in my case $2150 for max HP riders), pour out 5 riders and Vercing on 2x ATK, then protect them with your two spells as needed.
