Megumin's explosion spell drains her to the point where she cannot move, and she can only use it once a day, but could she move if she had more MP (or whatever equivalent *KonoSuba* uses) for casting? It could be that the spell cost is defined such that it drains all MP. But we see in some episodes Megumin can cast the spell twice if Kazuma uses his drain spell to give her more MP. So, is raising your MP a thing in *KonoSuba* (I'd think it would be, since it has an explicit leveling and stats system), and could Megumin potentially move after casting her explosion, and maybe even cast it twice in one day if she doubled or tripled her MP?
