Hello.
The rules for units of Giant Rats state how many Packmasters you can have at maximum.
Quote from Armybook: Skaven.
A pack consists of 1 Packmaster and at least 5 Giant Rats. Any number of Giant Rats can be added to the unit. Additional Packmasters may be added, but no more than 1 Packmaster per every 5 Giant Rats.
Can I add a Packmaster for every 5 Giant Rats in the unit?
Or can I add a Packmaster for every 5 Giant Rats i bought in addition to the Giant Rats that are included in the base size of the unit?
Example: Is it legal to buy 3 Packmasters (giving a total of 4 Packmasters in the unit) for a unit consisting of 15 Giant Rats? Or is ist allowed just to have 3 Packmasters at all?
