I've been debating for a long time what to use for Devout blood hunters. Recently I came across Leviathan Dragon brood riders again and decided to make the plunge. Picked up 7 of them and some bits from the war store.
Here's the dragon brood rider. . . pretty good scale for a size 2 model, and has a similar "chronopia" feel to it. Didn't really care for the head. Not "devout" enough for my taste. The miniature also comes with a spear, but the blood hunter has javelins, sword and shield.
Here's some examples of the bits from The War Store. Right handed sword, head, and simple "milliput" epoxy putty "javelin quiver".
