I'm new to the hobby. Zero games played. I bought the Start Collecting Orks box, the rule book and the xenos 2 index and I have some questions. If anyone with the knowledge could help me out that would be much appreciated.
1. A Painboy can use a Killsaw instead of it's Power Klaw. But assembling the Painboy was pretty linear and there didn't appear to be any Killsaw bit. I'm honestly not sure what a Killsaw looks like, but stat wise it seems to be better AP and more consistent with damage so I'd like to use that instead of the Power Klaw. Do I have to "kitbash"?
2. Every unit of Boyz can have a Boss Nob. To make a Boss Nob, do I just stick a war leader banner or whatever on one of the Boyz models?
3. Warbosses, weirdboys, Nob With Waaaagh! Banner: can I just use the Nob or Boyz models and put a staff or leader banner along with the proper wargear on them to make these? Or do I need the actual models sold as Warboss, Weirdboy or Nob With Waaaagh! Banner
4. Nobz: Every unit can have 1 Boss Nob and every model maybe accompanied by an Ammo Runt. Is the Boss Nob just a Nob model with leader banner? There's only one Ammo Runt in the box. I don't see any Grots or Ammo Runt kits... are these the same as Gretchin? If I want a unit of Nobz with 1 Ammo Runt for each model in that unit, how do I go about getting those models?
I didn't find the right solution from the Internet.
