Hi there, just rolled a custom faction, and not sure if it is part of the design that the Slaves of the Quendar race does not gain the bonus of the "Lucky" upgrade (the slaves was the only reason I picked it
), They do not gain your bloodline bonus, but then again, why should they not be a little bit lucky in combat? 
I consider my slaves very lucky, I haven't killed them yet, they get to prove they're worth in combat 
Sincerely
