Here is another one for the purple Cryx project, the always useful warwitch siren. This is one of those solos that I often find room in my lists for, due to her power booster ability. She can give a focus to a 'jack, providing that it has no focus already. This can be useful for saving focus, or in tandem with a jack marshal, but not so much for her other abilities.
This colour scheme fits her well I think. It is a really nicely sculpted mini, even after the odd helmet she wears, and very Cryxian with the spikes and tattered skirt.
