Really stupid question about Obsessions

So, I'm perusing my Drukhari codex, as I'm considering playing again now that I have more time.

Am I missing something? It seems inconceivable to me that the Drukhari Obsessions rule would apply to vehicles, but I'm not seeing anything that says it doesn't.

Does it?

If it has <Kabal> <Coven> or <Cult> in its keywords then yes. Page 114 will give you the finer details. but in general, yes.

for example, a voidraven bomber could be an obsidian rose, so the weapon crafters would of refined the armaments to their specification and given them more range. things like that.

Yeah, its basically only Marines that dont get Traits on vehicles. SoB does, all Aeldari does, some IG does, some Chaos does, etc..

As rule, anything with the <Keyword Trait> can get rules unless otherwise stated
