other: torvus energy skip
After you get the dark visor, enter the next room and go to the very back of it, then return to Dark Torvus Temple. If the door doesn't open right away, you went far enough. Now the elevator will be active and you can leave Torvus without collecting the energy.
- It's still necessary to collect/return the energy in Sanctuary Fortress, but that's the only one you need for the light suit.
