"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

Considering how Biara is being developed, it's hard to significantly weaken her by making him a secondary hero, unless he masters skills like "Inspire" or "Berserk" and turns Biara's troops against each other.

Did you take two dwarven treasure chambers on the first part of the map?
You get a level immediately for that.

Not a hero, I cleared everything I saw. Zephyr is level 32. I spent experience on Thunderers every week. And I also spent some on the city. It's unlikely I'll reach level 33. However, I don't know how strong the remaining neutrals are. I'll find out soon. In one mission, I managed to get 0.5 million experience from one group of neutrals.

Where will a secondary hero get "Inspire" or "Berserk"? Unless it's in my castle. I didn't check what's available in the guild. I don't remember if there was a mage treasure chamber. There's a lot of good stuff in this mission. Something guarded by mages appeared repeatedly. There were definitely no pyramids or utopias. I probably won't level him up.
