Worshipper – “Ship” [Campaign 2, Mission 4]

You're wrong...
You can travel by sea:
-firstly, why have a ship if you can't use it...
-secondly, it's faster by sea - I've tried it myself, the main thing is to land in the right place ;)
-thirdly, in addition to the second point, you can research scouting....
By the way, we could organize an offline tournament for the fastest completion of the campaigns (version 1.6 or 2.1 or 3.1)...

Are you sure you're on the right topic? :rolleyes:
It seems to be about the next mission.
And for your information, it's easier to find Inferno creatures at sea, which you need to collect for the final battle.
Regarding upgrading Agrael, he should definitely have Logistics. In the first mission, if my memory serves me right, a sorceress will help you get it. And by the fifth mission, Agrael will be a monster in terms of the attacking power of his creatures.
