How can I beat a campaign in Legendary difficulty when my enemies multiply exponentially while I can summon one unit every turn? Right now I see 25 enemies on the screen and two units for me. After some desperate efforts I could positionate one unit next to the enemy shrine, but it is impervious!! So I assume I need to clear the map of enemies before attempting to destroy their shrine. It is not legendary, it is impossible. Were these campaigns expressly created to never be fulfilled or there is a secret to win? I was thinking in purchasing campaigns to get the rewards of the limited runes but if the situation is this 25 enemies against you as you only can summon one per turn I think I will pass, I just do not have the nerves to try the same encounter 100 times until a strike of luck helps me. So if there is a secret to beat campaigns set on this level of difficulty, tell me, I am eager to know.
