Welcome to Librarium Online!
I noticed in the rulebook that a tyranid boss for kill teams is a "weapon beast" or something like that. What is this supposed to be? I'm thinking warrior but I'm not quite sure.
It didn't tell me what a tyranid boss is but it was actually a nice article. It gave me a couple of ideas. Thanks.
That would explain quite a bit.
I guess I'll just use a warrior or something.
