Orcs – discussion about the race.

So, these Orcs are just clumsy. Against the Undead, you take the Darkness skill and terrorize the artifact shop. That's all you need. And, of course, the troops.
Personally, I've only played against the Undead a few times with Orcs, but I crushed them and kept 75% of my army.

Yeah, of course... For Orcs to easily defeat the Undead is pure fantasy, because Darkness always decides the outcome against Orcs, and the Necromancer has it better than anyone else. And also summoning. Personally, I've always considered the Necromancer the most dangerous enemy of the Orc. Reread the topics in this section; everything is explained in detail there.
