As more and more Barathu are surfacing in the SFS, here is what I still don't see any obvious answers to:
1) Do Barathu get features from Aberration type (at least, Darkvision)?
2) Can Barathu speak audibly?
3) Do they have two default "hands" to wield weapons, as per generic equipment rules?
4) Not having a land speed, do they need to spend move action and roll Acrobatics each turn just to keep in place?
5) Is their extraordinary flight influenced by heavy armor speed penalty?
6) How should they handle the systems for augmentations? Can they slot Speed suspension (which clearly requires legs per se)?
