I like Whitehack so much I just purchased extra copies so I can send them away to friends, and I'm looking forward to running it soon. 

I still don't think I have a handle on Deft characters being attuned to objects, particularly that they use them once per day. There are several examples in the book. The first is a monk and his walking staff, and the suggestion is that the monk can use it both to throw or to knock arrows from the air. If the monk's attuned, does that mean he can only use that walking staff once each day to do one thing with it? 

The next example is the ranger with the dog. Can he, then, only command the dog once per day? 

I feel like that can't be right and I'm hoping someone can explain the matter for me.
