I set up another game of Dragon Rampant the other day, using the Orc warband from the previous game, and an Elven warband. I created some random terrain and selected a scenario at random as well, getting the basic Gory Bloodbath fight.
Elves are on the left, with 1 x Heavy Rider with Blessed Weapons (Leader), 2 x Heavy Foot, 2 x Light Missiles and 2 x Heavy Riders. The Orcs once again fielded 1 x Elite Rider with Level-Headed and Fear, 4 x Light Foot and 2 x Heavy Riders.
The Elves are a tough proposition in this scenario, which is just a straight battle. In a more involved scenario this pairing might produce some more interesting results.
