Splitting Zombie Swarm
Basic concept is to have a huge swarm of zombies that eventually breaks off into smaller swarms that are one size category smaller(max medium). I don't have a monster sheet posted because I'm not sure how tough of a monster this kind of feature would be on.
1. Start off huge sized, and gets one attack per round for each square it occupies.
Deals lots of low damage dice, and which is halved for each split.
2. Each hit breaks the zombie swarm into two, and reduces size category by one?
The zombie swarm breaks at bloodied, with half the bloodied total for each break?
3. Each hit has a chance to inflict some disease. But what?
4. Standard xp? Minion xp? Maybe even Elite?
5. I want it to die if it is dealt enough damage to run out of hp. Which means the split would be an immediate reaction, right?
6. At medium size, it can no longer split. Or should medium split once as well?
