So, does the Blackguard get the Bio 3d6 Sneak in addition to the selectable sneaks at level 3, 6 and 9?
Can a Blackguard use the Bio Bull's Strength feat? The Avlis wiki says it is divine spell casting. Does that mean that a Blackguard needs to sink points into WIS as well as STR, CON and CHA?

Does a Blackguard get use poison? contagion? create undead? etc..
I think I'm just really confused by the differing descriptions and how they do and don't merge. And since there is no way to test an Avlis Holy Warrior build locally...
