Well there it is. Stealth Mawloc is nigh on invulnerable because you can't see him. He isn't even on the table. This ultimate stealth bomber appears randomly, drops two blast templates and then mishaps off the board or back into reserves. GG.
Mawloc conversion complete. A bit of an under performer, but I love the model. Once you explain to your opponents that this subterranean killer can deliberately deep strike underneath the enemy for strength 6 damage, you might see a flicker of anxiety cross their face.
