So one of my players is interpreting the rules for the Cleric interestingly.

"Each cleric must choose a time when they must spend one hour each day or in quiet contemplation or supplication to regain their spells." They understand that it's implicit that you can only do this once per day, but they're (mostly jokingly) saying that since it's not explicitly stated in the section, that one could argue that a cleric could just keep meditating to keep getting spells back all day long. Thoughts?

Edit: I told them as such, and they understood as such, but they thought the wording was a little questionable and I promised I'd pop it on here. Thanks for the clarification, folks!
