Ice and Fire

Heh, that reminded me of a trick about subduing creatures.

The hero levels up to become a mentor and trains other heroes. They reach level 25 and also gain the ability to subdue creatures. All these heroes attack the boss as a group. Several heroes will significantly reduce the enemy's troops. The main hero then switches back to his original build.

It's quite a cheat, though =)) I did the same thing when I was playing through the last campaign as Zehir. I need to use it here too. The main thing is to acquire the ability to subdue creatures.
