Spawn: Taking this ability allows you to grant the Spawn Template to other classes. This ability may only be taken by a Level 3 Class or higher allowing you apply the Spawn Template to a Level 1 or 2 class with the following rules.
...Spawn can never take coordinated squad/group bonuses to their combat situation. Nor can they ever use any weapons or armor other than primitive melee weapons with a threat range of 1.
Monsters come with the restriction to the Armory only allowing for either Claws or Bite as their weapon. Does this imply that if a monster class you want to apply spawn template to has to have the "Primitive Weapons and Armor" trait, or are they considered to be using their weapons improperly and they now count as primitive weapons?
