Plague vs undead

[~Sapphire~]

Hello,

I was wondering how much effect/what effect the Plague will have on ponies that are 'undead'?

Database description:
Users with this power lack physical weaknesses, such as pain, need to rest, vulnerability to basic environmental effects (such as extreme temperatures), etc, while some still need to consume various substances (blood, flesh, life-force).

It would effect them the same as others because magic plague.
