I reflected light onto the top left axe but when I aim the light at the large rectangular thing above the forge, nothing happens. The game tells me to shine light onto it when I inspect it but again, nothing happens. I've tried using the wind power to hit the crystal from every imaginable angle but nothing happens. I summoned and beat the snake guardian above, but nothing happened except that the glassweaver duplicated itself and apparently considers itself a resident because it started a party the next day. Bugged? Am I missing something? It's really hard to tell.

Also, I used the wind dash to break some of those orange stamina things found underground, but as far as I can tell nothing whatsoever happens. Bugged? Am I missing something?
