I am sooooooooo tempted to max my warrior CotD and Nomad with skill shards, then combining them with AoF... Child can produce more than 17k to SSD on GoD with Nomad's buff now... Only I lack a decent Eddie to lead them. I'd love Visions to remove some Shells from enemy right away.
As for voids, seems to me that they only do not react to physical damage (Pris, Pharaoh, damned gunner CR), magic seems to be in order. Also, for a long time there is one where SSD/ sentinel BB from def team (never on me when I'm attacking) with Invisibility active misses the perfect hit and yet he doesn't lose it but it just fall down to 2. Luckily enough, I think it never costed me points, but is annoying af.
