Zombies!

[Ruethgar]

So, I want the Zombie virus, preferably official. I found a disease that converts people to zombies if they die from it in a Dragon Magazine, the only trouble is that you can't die from it unless it is made sentient by an 8th level cancer mages and makes you commit suicide. The other trouble is that it is ingested only which isn't a great means of infection. So I either need a way to make a disease deadly and change it to a contact or injury ailment, or I need a new zombie virus.

I'm pretty sure Libris Mortis has rules for plague zombies.

You could also re-fluff Ghouls as infectious zombies...

This relatively recent thread (http://www.giantitp.com/forums/showthread.php?366551-Walking-Dead-in-D-amp-D) had some pretty great ideas tossed around, including an excellent modification of the zombie (http://www.giantitp.com/forums/showsinglepost.php?p=17927152&postcount=7) that makes it better-suited for zombie apocalypse scenarios (including statistics for the zombie disease). Not official at all, but definitely a good place to get ideas from.

Just use Ghouls. A good CR and a larger threat than actual zombies. You can remove the paralyzing touch and make the disease worse, if you like.

Didn't find anything in Libris Mortis for a zombie plague. I can add magical side effects onto the supernatural disease, one of which makes the disease an injury and potentially inhaled infection and the other makes it deadly(at least to low levels). It is still within the rules and I keep the classy title of zombie instead of copping out with a refluff. Still not insanely powerful, but throw in some evolved zombie lords from Ravenloft and we are good for a pretty nice plague.
