I am trying out a new Daemon army list, and graymatterblues was the first victim. The Overlord has a Ring of Magic, one Sorcerer has the Wand of Power, and the other Sorcerer has the Rod of Repetition (making him popular with the ladies, I'm sure

).
The 'minor effect' that I received was that all units would pass the first order on the first turn. I was careful to make sure that I could order all units the first turn. It is rare when you can rely on being able to move everything! So I made the most of it.
In the third turn of the game, the Overlord got off an obscene string of command rolls, which allowed him to bring a brigade of cavalry from my left over to my right and charge into the combats on Noose Hill and in the canyons. I think at least 3 command rolls went off within 20 cm of an enemy. This allowed me to decisively destroy the Wolf Riders.
I definitely like having more terrain on the board!
Another little quirk: When I initiative charged the surviving Wolf Riders on Noose Hill on my turn, I lost a stand of swarms due to some good stand and shoot die rolls. That was during the movement phase. When the shooting/magic phase came around, I summoned a stand of daemon swarms back into the shot-up sawrm unit. In the ensuing combat phase, two stands of swarms were destroyed. At the end of combat, 1 stand survived. This was odd. The unit took 12 hits but was not destroyed!
It was a fun game. My Daemons look forward to eating more Orcs on the battlefield in the future.
