A question about the Restoration spell

[Storyteller31]

Hey all. I've got a question about how the restoration spell works, and thought i'd pose it towards the fine people here on the 'boards.

First, the important part of the spell...

"This spell functions like lesser restoration, except that it also dispels temporary negative levels or one permanent negative level."

How many temporary negative levels would you think it dispels per casting?

It dispels all temporary negative levels.
