In Mutants & Masterminds, you can purchase a sidekick as a feat.
I'm rolling up a knight, and I want a squire, using a similar game mechanic.
Is there anything like this in D&D, other than the Leadership feat? I don't want a small gang of cohorts, but only one follower.
Or would this just be a 'the GM rolls them up as an NPC and you wing it' kind of thing?
