Is there any mechanic anywhere that covers or allows for recharging of wands?
Preferably cheaply if not totally free.
None.
That was quick. Lol. Thank you.
Closest there are are mechanics that allow you to spend other resources instead of charges, but none for replenishing charges themselves.
None that I know of, I allow it with craft wand just paying for the charges and spending the time.
EDIT: without needing the spell available each day.
