How to Paint Maulerfiend

The Maulerfiend is both fast and capable of doing significant damage to tanks. Because they are Heretic Astartes, they can be the target of Warptime. They are also a perfect target of the Daemonforge Strategem. Run him along with a Vex Macchinator to give him the +1 to hit, which improves his base WS. Expect that they will draw a lot of attention from anyone who doesn't want their tanks ripped open. At it's top Tier it has 4 Attacks, and regardless of if you use the Tendrils or the Fists, you also get D6 more attacks with the Tendrils. The Tendrils are Strength "User", which starts at 6. The Fists are Sx2, for a potential 4 attacks at strength 12 - and more if the target is imperial because of Death to the False Emperor.
