Held charges question.

[hairy old lady]

If I cast frostbite as a level 5 Magus I get 5 charges to use. Do those charges continue to be held if I cast another spell?
So could I cast frostbite on turn 1 and shield on turn 2 and still have those 5 charges to use?

Is it casting another touch spell that make those held touches dissipate?

[Nefreet]

Casting another spell makes those charges essentially dissipate.

[Pupsocket]

Casting *any* spell makes a held charge dissipate.

That's what I thought but someone said otherwise in another thread and no one pull him up on it, and when I questioned it I was ignored.

Thanks!
