I was hoping for a second that sightseeker would be a fighting style I brainstormed and then never convinced myself to get around to developing into a suggestion but then remembered that it’s a magic type. Though it could totally be a magic type with a similar premise, removing one’s regular sight in favor of greatly enhancing sensing beyond normal limits. Though I do feel that stuff like seismic sensing or ultra instinct are powers that fall more within the realm of martial arts than magic, though there is always a bit of both present.
Y’know between this and one other thing I saw leaked, I have some small hope that my ideas may have actually inspired some recent development of the game’s features and lore. It’s just two little things but I don’t know.
