I might have a make a mistake about Captured Shamans earning teefs as slaves, see Digganob p.27 : "The Digga may be added to the Mob roster like a hired Digga and all the rules for having a Digga in the mob apply." So does this means that a captive digga become a full time member of the ork mob or remains some kind of a slave able to fight for them ? there are a few differences between these :
- if members (like hired diggas), boyz and yoofs will generate D3 teefs, Shamans 2D6 if they succeed a Ld test, and Digganobs nothing at all. They will also count towards the size of the mob when calculating the profit from the mine and will count in the ork mob's value.
- if slaves, all of them will generate D6 teefs, no matter their type, without counting in the size of the mob or its value.
I'm not sure about which one is the most RAW or RAI, but the first one seems a bit weird : I don't see why a captive Digga should be working less than other captives, or why a Digganob shouldn't be digging at all ...
