So my gaming buddy for the last 27 years and I were discussing ideas and I thought about a wand that stores spells for wizards. The way it would work is it could hold a max of ten levels of spells (example two 0 level and one 9th, three 2nd and a 4th, etc.) they have to be spells prepared and unused that day and can carry over until used, so long as they do not exceed a total of ten spell levels. How does it sound? Worried it's to much like a ring of spell storing.
