Title pretty much says it all. I guess chameleon skinks cannot be included in the Heavens Watch battalion guys ?
Sadly you cannot. You could also run small shadowstrike starhost with them to get the benefits. Clarification Edit: By benefits I mean the re-roll 1s to hit and wound. Also having the two would give more artefacts and allow you to pick one unit for your main force and one unit for the shadowstrike to attack.
