How do you calculate CR for running battles?

4

I am creating an encounter for a game I am DMing and am wondering how you calculate CR for a running battle. What I mean by this is that characters will be fleeing through a zombie infested town, with zombies popping up at regular intervals(every 2-3 rounds).

Theoretically, the battle would never stop, so it's effectively one encounter, but I don't think standard CR calculations would work. 15 CR 1 monsters at once is a lot harder than 15 CR 1 monsters in groups of 1-2 in a steady stream.

Any guidelines on how to calculate an appropriate CR in order to balance this?

It depends. If the encounters are começado every 2-3 rounds and they don't overlap, I would not combine them with as if they were one encounter, as that's intended for concurrent enemies. You should take into account they cannot rest in between, but if they are otherwise separate encounters, the EL would be as if they were independent. If you anticipate them overlapping, but starting 2-3 rounds apart, then maybe determine EL at one encounter combined with the next. In any case, unless you anticipate all enemies surviving until the they are all present, definitely do not combine them all or it will be way too easy. Best of luck!

Unearthed Arcana began the idea of an XP budget, with Level-Independent XP awards, also used by PF and other RPGs, but I think this is a good application. Simply add up the XP and try not to hit them with more than 5 times a normal encounter, since that's all they should be able to handle before resting, but it's not a very accurate science since seemingly little things like special abilities or immunities can dramatically change things. Normal speed zombies might help mitigate this.
