Is it that big of a deal? At worst you can always partake in the created food my character makes at the end of each day (I create enough food for the entire party, 3 people or one large creature per level), which will keep until the next day. Also note that just putting it in a 5th level spell slot doesn't actually increase its effective level or DC--you need to use Heighten for that.<br/><br/>And wouldn't having to heighten it be even worse? That way it takes one of your highest-level slots, rather than a 1st-level one.<br/><br/>EDIT: Just a quick note as well--Call Lightning is a 4th level spell, so you'd need to cast it from one of your 3 scrolls for the day. And since all your equipment melds into you when you wildshape, I don't think you'd have the scroll handy, so you'd need to un-wildshape to get access to it.
