Ahh, yeah OK. My party are all down at 3rd level at the moment. We haven't reached the heady heights of totem bears yet...
I can see good and bad in daily recharging items. Something that does it's thing once per day is one thing. Having 10 charges per day might seem a bit too powerful. Although, the Wand of MM has 7 charges, and I think it is a great item.
To me, having all that rechargeable magic makes it too easy. Just save that last charge, and even then it is what, a 5% chance of being destroyed? I would probably houserule that into a much more dangerous percentage instead of 5% across the board.
We haven't used charged items a whole lot, although someone did have the wand of magic missiles that came in very handy.
