Ok so my nurgle follower got himself a reward, which is a nurgling infestation. I can spill my guts to have 4 little mischeivious gits unleashed upon my foes, cackling and giggling and generally having a great time. One problem though, I can't find any rules for nurglings anywhere, have they been released in one of the games for the other books? Have I missed them in BC somewhere? Or should I just attempt to stat the wee bundles of disease ridden joy myself with my GM?

There are not Nurgling stats in BC core book. Surely, it was because a space question in the book.

You can find stats for them in Daemon Hunter for DH. Or you can houserule them

Was looking for a reason to buy Deamon Hunter anyway
