The Wych squad is proceeding quite well - they are however much more time consuming than the Warriors with all the skin and such.
Pair of Hekatrii:
Both have a blast pistol and agoniser (I'm using the swords instead), but one has a phantasm launcher.
Group shot of the squad:
As opposed to the warriors I'm giving them yellow tabbards rather than black, mostly so they're visable at a distance rather than looking like a black smudge.
Hope to have them done in the next couple of days, then on to some Reavers.
