The Necromancer's Path.

He didn't know about the army calculation for Wessel – he didn't fight him that much.

Generally, yes – he just started leveling up the second hero too late, so he spent a lot of time locked in with them.

There are many saves left (there are even early battles, when they were difficult and he had to replay them several times).

One of them is from before the battle with Wessel.
