One night on some mountains I had a battle against Tzeentch himself, who somehow got an army of Demorged Orcs. Demorging is process of reviving fallen and defeated units as a sort of puppet-like demonic clones. This time not only I used Ultra Instinct but I also got some orc tribes on my side. How? Well, all I needed first was Ulu-Mulu. An orcish weapon of peace.

Ulu-Mulu belongs to Piranha Bites.)
