Warhammer swarms?

Question

What is the base size for a swarm of nurglings? I'm trying to take some reaper models and transform them but I don't know what the darn base size is lol.

Answer 1

You again? ;)  There was an A4-sized summary card published with White Dwarf back when the latest edition was released.  If you can get your hands on it, it gave the minimum base sizes for all the (then current) range of Warhammer models.  I don't have it immediately to hand (I happened to be looking at it when you asked you question about daemons) but I believe all swarms must be on 40mm square bases (minimum).  I'll check and edit this answer if I find out different.
