The Cryxian Heavy Jack: Everyone has read the facts about Cryxian heavy jacks before, high defense, low armor, high hitting power, small damage grid. Our jacks are fast though... incredibly fast, and often allow us to bring the pain where we want it. My personal experiences with helljacks are confined to the Slayer, the Leviathan, the Reaper, and the Seether. The Deathjack also has found its way to my table, but we'll save him for another blog entry.
The slayer is a heavy jack costed like most faction's light jacks. When I first started WM a few months ago, the slayer found its way into all of my lists. Skarre can load a slayer with focus and it can tear apart anything short of a Khadoran heavy jack with ease. The two open fists are tons of fun enabling all the throw shenanigans you can think of. Recently, the slayer has been more of a body guard for my casters. Kept close to intercept anything nasty that comes their way. The 6" move gives him plenty of threat range.
I'm still not so sure how to use this bad boy. I started a thread on the PP forums that went on for a week as people argued for and against this jack. In my eyes, the no knockdown and rather impressive ranged attack make it a good choice if you have a caster who can fuel its focus habit. This thing is the crack head of focus. It needs all three focus to be efficient, one or two focus just won't cut it. My favorite trick of late has been to couple this with eSkarre so procing Black Spot can lead to 6 shots, great for thinning infantry or for putting a whumping on a heavy jack. Worth mentioning is also the fact that this thing is amphibious (see my base!) which may seem kind of pointless, but we have a few water features in our terrain respository which allows my some interesting options. I love the look of this jack, and thematically he fits with my "Black Ship" army, so he figures into my lists quite often.
Other than my propensity for the Mortal Kombat line, the Reaper is just not my favorite jack. The harpoon is cool, but I can't seem to ever get it to land, even boosted. I'd rather save the point and take the Slayer. I have run the Reaper with my Black Ogrun in a crazy "let's move everything around" list, but in the end it just seemed rather silly.
Best. Jack. Ever. Period. Free focus every turn, free runs and charges, hits like a tank, chain attack for free power attack... the Seether has become my favorite jack and my main assasination tool. The Seether is so focus efficient, it's feasible to have a turn when you don't allocate him any focus, and he still can go to town. Coupled with a Siren, the Seether really rarely needs his warcaster to give him any help short of buffs. The Seether is in pretty much every one of my lists these days.
Painting wise... here's the three Helljacks I have finished. I've continued my beach bases on these, including the leviathan who is still in the water. The seether is the only one to pick up the purple that is the unifying color of my army. Any comments on the other Helljacks would be very appreciated!
