Zombies

[jocosa]

I know there was a post in the forums, regarding Zombie/kill math. And I can't find it. It basically talked about how you could kill 5 dragons by a certain date, and get those kill slots back again on the 31st, while still being able to use resurrect on that first batch of killed dragons. Thus allowing you to try for more Zombies then if you had just gone for the 5 kills on the 31st itself.

Does anyone know the post I mean, or if not, help my addled brain with it?

Ideally what I'd like to get this year is 1-2 more adults, and 2-3 hatchies.
