Cult of the Lamb

Followers in Cult of the Lamb are expendable resources and I recommend you use an "easy come, easy go" philosophy regarding them. With that in mind, you'll earn this cheevo pretty quickly without trying to. You'll get them by defeating bosses, finding and rescuing them in the wild, and buying them from Helob. I should add that I believe the cheevo description should read "have ten followers at the same time", which is still not difficult at all.
