What is the Max number of Zombies from the raise zombie skill

Does anyone know the maximum number of zombies that can be following you at once with the raise zombie skill?

Thanks!

3 Zombies by default plus 5 nodes that grant +1 each. So, 8.

There are several uniques available that can add a couple more. I personally think they should also grant an additional zombie once your reach a gem lvl of 22 or 23 (possible by maxing it out and taking advantage of the new affixes on items). That would be fun.

Wow, that is a pretty high number. And that doesn't include spectra and stuff like that. Thanks for the help.
