I'd like to present another argument in favour of Have Eyes, or more precisely against athame.
Issue the first: I believe it's going to be a bit redundant as a defense tool. We have revolver, Penelope and her martial capabilities, Destroyer and Arcanum.
Issue the second: I recognize ritualistic use of athame, but I want to point out that the kind of ritual magic it would be involved in (black robes-ominous chanting-bloody sacrifice occultism) is not exactly appropriate for our Role. Magician
uses the power of the Outside through reason and will, not worship - that is domain of Hierophant. And even though Magician would not be forbidden from such actions, remember that the Role is more than the title. Sol is not just the Magician, he's the King of the Magi. Magician that would use athame and cult-steeped ritual magic would be an Occultist. While our Role is still malleable, I believe that we should maintain thematic resonance if possible.
Related, it might just be me, but I don't think Sol would appreciate black robes-ominous chanting-bloody sacrifice occultism on a personal level.
Issue the third: related to issue the second, if the Box is some sort of Genesis Device, notice the thematic resonance with KotM. Kings build their realms. We can do so literally.
Still counts,
@Birdsie ?
