Unfortunately, I only have one huskblade and it's already in use.
(I seem to have a thing for winged HQs.
I was initially considering a head-swap but I really like the scourge head. I'm messing around with his wargear at the moment, but so far my favourite option was a simple blast pistol and dagger (or a blast pistol and venom blade, which doesn't help either). Still, I'll seen if I can find anything more interesting or convert one or the other in some way.
Decorating the base is a good idea, I'll give that a go.
One other thing I was considering was giving him a tail, possibly made out of a Necron Whip Coil. The main issue is where to attach it and how to get said attachment to blend in with the rest of the model.
Thanks for the advice.
