Complex magical systems on Equestria, the notes explain, when used in or around animate objects, tend to spontaneously demonstrate emergent sapience. Many animals in more magic-rich environments like the Everfree Forest – apparently a location near where she lived – display intelligence above and beyond expected of them by large margins. The spell should be crafted in such a way to minimize this possibility, lest the hands literally develop a mind of their own. It goes on to recommend each hand be animated separately, even though this will increase the amount of time needed to acquaint a user with their function. Efforts taken to lessen the load per-channel on the spell are unambiguous improvements away from this possibility, but more important is cutting back on the number of channels where possible, even if this requires the spell to do more work overall. Omitting every other feedback sensor is an option, letting the spell figure the gaps between the ones that remain on its own.
