Hellblades are capable air superiority fighters if deployed in high enough numbers. The Death Guard capitol ship Harbringer of Woe carries large numbers of fighters such as these, and they were active in the skies of Neu-Diemensland prior to the deployment of ground troops.
This pict capture was taken during the late stages of the air war, prior to the mass landing of ground forces from the Death Guard.
After a solid performance in the early days of 40k 8th edition I decided to reward it by finishing the paint job off to a standard that I was happy with.
As you can see (through the haze that is my lack of photographic skills) I added a few details to this model; some spooky fire things on each side and at the rear jet, and a couple of chaos symbols on each flank.
The colour scheme is that of my traitor guard army, the Togari 88th, but goes well with my death guard army as well.
Edit: I forgot to say, but during my last game against Aeldari, my opponent had Eldrad hidden up the back in some ruins, buffing the army. A highly mobile hellblade should have been able to get into a position to threaten Eldrad, what with it's 40" move and agile special rules. While it isn't likely that it would have killed him (one turn of shooting would on average inflict 1.55 wounds on him and he has 6 wounds), its chances would have been infinitely higher than if I didn't try. Plus he may have moved forward, putting him in threat range of something else.
So, as is always the way, when a new edition drops learning to use tools like this presents some fun challenges!
