This has been bothering me for a long time. On the resistance, it says that it has a resistance to :fighting: , but it doesn't say -30. Does this mean that Zubat takes no damage from :fighting: types, or is it just a printing error?
We never got an "official errata" from WOTC on Zubat, but I'm pretty sure they chalked it up to a printing error. Resistance is always -30, unless you have something like No Resistance Gym which changes it otherwise.
