PSU-Item: PM BSt Question

[Nisshoku]

Well, I'm currently trying to power-level my PM's BSt for tomorrow's update. What i'm wondering though, is if I get up to BSt 10 and get a PM EX GH-470, will it retain the BSt that I had previously attained for it, or will it go back down to 0?

We have to get a JP player to tell us becuase everywhere i have read no ones noes or sure.

It should stay at the current PM B St, I don't know why it would go back down to 0. The only way to reset your PM's B St is to feed it a PM Device ZERO.

I wondered the same thing, but it doesn't reduce your battle stat when you use an EX Device.
