Teun here. Just played a game of 40k today against the lovely Swanky Tiger, but in a departure from the normal, she played a force of Dark Angels today. 1500 points, Dark Angels CAD vs Black Legion Warband.
In this warband, I took a sorcerer with 2 extra mastery levels, a spell familiar, and the Last Memory relic, giving him an effective mastery level of 4. I said "why the hell not" and rolled all my powers on Pyromancy, which although not the most powerful of the psychic discliplines, they are a hell of a lot of fun!
Due to the relic, he already had Sunburst. Rolling for 3 more powers, I generated Spontaneous Combustion, Inferno, and Fire Shield, in addition to having the Fire Breath Primaris power.
Using Fire Shield was interesting. On the side of the board my psyker was on, a unit of Ravenwing Bikers was attempting to shoot up the board edge. Being able to shut down that avenue of approach by making the terrain both difficult and dangerous was pretty awesome, as was blasting them with a multitude of cover-ignoring powers.
The finishing coup d'etat to the game was a timely double-tap of the enemy Interrogator Chaplain, wounding him first with Inferno and finishing him off with a Spontaneous Combustion focused witchfire.
I took a CSM lord in Terminator armor, usually the model I use for Abbadon. In this case, however, I used him simply as a Lord with a Hand of Darkness and a combi-bolter. He didn't do much but objective baby-sit.
I won the game eventually. It was a simple Scouring mission, and I held 4 out of the 6 objectives, as well as secured Linebreaker, First Blood, and Slay the Warlord for a combined total of 15 VP. Swanky held 1 objective, worth 3 VP.
