hi, thank you so much!
i didn’t think of foci as recharging, especially since that would mean players could get one and be done. however, it makes sense for a mage to be able to recharge a focus, so i’ve added a rule saying that :)
also i thought of foci as being like wands or staffs, but ritual daggers and similar cool items would be really neat! there’s not a rule for what they should be. the text is focused more on function than form, but you should take that as an invitation to make the form interesting to you and your friends.
