Magesight has many advantages over conventional vision, but one that it lacks is depth - regular sight has two eyes, but Magesight only has one soul
Huh, I wonder if having a Familiar can address that?
That is, a mage's Familiar has a soul of its own, right? Can Familiars develop Magesight -- or, rather, can the Wizard use their Familiar as a second source of the Wizard's own magesight? (Because I bet even if a Familiar somehow could develop Magesight, they either develop the exact same type as their master... or they develop their own unique sense. And, well, they're a Familiar. Not a human. Being able to both See and Smell magic would not help in trying to See things unfortunately.) Because that way, you'd get depth perception in your Magesight. One from the Wizard, and one from the Familiar channeling the wizard's sight?
... Actually, another thought.
That Seviroscope thing we brought up long ago. Could that also be applicable here?
That is... If Mathilde had had Magical Goggles Of Magesight (probably by doing her own enchanting of some goggles, so that way the magic item would have her own type of Magesight), could she -- when using her own native Magesight in addition to the goggles -- have resulted in her having depth perception?
Or failing that, could developing Magic Spectacles result in binocular -- or better, fancier, like telescopic, or something -- vision?
That could be a cool thing to explore. (... In our copious and totally-not-limited-at-all free time. >< ) It'd be an interesting way to approach something related to the Seviroscope topic though. If for a different purpose and for another sort of goal. i.e. First you try to solve for 'improved magesight or gain depth perception', and then if you meet with fortune there, maybe it'll end up with discoveries or developments that'll be useful or neat and which can eventually lead to that stuff.
Also, for a different topic and approach... Namely, on the topic of 'navigating in pitch blackness' rather than 'speculating about how to do interesting stuff with magesight'... Just commission an Enchanted Item of "X-Ray Vision" or "Magical Nightvision Goggles" something. Sadly, this sort of thing probably would be best with, I dunno, Hysh or Chamon or something and would probably be one of those 'this needs to interact with your brainmeats to work' magic items. So it'd need to be Ulgu-only. The Nightvision Goggles might be doable with Ulgu though maybe? In which case we
could use it. It'd probably have to take up and replace an Activatable Item slot to do so though.
