Greets,

I mentioned this in the "Fantasy army lists" section, but its more appropriate here:

Are there any restrictions on characters joining units when marks are involved? For example, a tzeentch marked champion joining a unit of nurgle warriors?

The only reference I can find in the army book is on p110, where the marks are detailed, but that just describes what the marks do. The FAQ I have is from Feb 09 and doesn't mention anything either.

cheers.
