Wizard – “Hope of Zephyr” [Campaign 6, Mission 5]

I didn't get the joke... Faidean needed to break through a magical wall – so, remembering my first bitter experience when I did break through the wall but lost a bunch of hunters and druids in a hellish wave, I hid all the archers and dragons in reserve, and put unicorns, treants, dancers, and one surviving pixie on the field... Well, there was one last hit left – the wall was about to collapse... After the waves and resurrections, there were still about 50 treants and 30 unicorns left – and then they tell me that the hero has been defeated! And the mission is lost! What kind of trick is that??

I'm sure that the poor skill build is to blame. Did you give him Education and Luck? And only Light Magic, but with all three derivatives, giving the ability to cast mass spells.
My Faidean turned out to be, perhaps, the coolest, because in the Campaigns there are many stat boosters and witch huts.

He has defense, logistics, light higher magic, luck, and summoning magic. He was once level 30, then on the third mission of "Mage" he was reset to 25, supposedly that was the limit. Then, on the "Alliance" mission, he leveled up to 26. The skill build is not bad – it's true that in his campaign he spent most of the points for levels on knowledge (well, he's a strange ranger!), but with the stat boosters, defense and protection are also at a good level. And in the previous mission, he was also doing great! But here, I guess I didn't keep an eye on how Biara killed the hunters – I didn't resurrect them – and that's why I paid the price...

I see... The Overlord destroyed my catapult :( I wonder how to make him NOT destroy it???
