Well I did it. I won the first scenerio with the Fubarnii today! The engineer didnt escape but instead killed the Kopa! ( I guess that was what he was working on when he wondered off)
Using the hex defence I was able to transport the Engineer safely a fair distance while my knights played very aggressively against the grishnak.
I almost lost when the kopa moved into combat with the militia and tried to assassinate its way through but the captain withstood the punishment managing to cast three Oran! which the kopa couldnt trump.
Then the engineer stands and shoots the blasted creature killing it
(the kopa had no stamina from sprinting and assassinating)
Super pumped from the victory as now i know it can be done! will play more to work out if i can do it without being put under so much pressure
