Heroscape D&D Wave 3 Expansion Pack: Moltenclaw's Invasion - Valkrill's Legion;

What the Ogre Pulverizer lacks in intelligence, it more than makes up in brute strength, frightening whole armies with a single swing of its club. The fiendish Mezzodemon Warmongers fight for anyone - for the right price. Their chitinous armor deflects sword and arrow alike, and only sturdy heroes can resist that poisonous gas they exhale. The corrupted Death Knights of Valkrill have made a bargain to serve destruction beyond death, but they have paid a horrible price. Their souls are now embedded in the blades they wield.
