Spoiler: Chest in Vah Naboris Dungeon

There is a chest that is elusive and hard to get to.

If you head to the tail section on the bottom. I don't see any way to get the content and most walk through skip over chests from what I seen. I don't see any water or magnetic objects that could act like a plank to catch it. For reference this is the chest I am talking about at 1:07 Link to Youtube walk through video The only way I can think of is to raise the tail section up and shoot it from there but harder to aim.

This chest is tricky to get since if I shoot the wire holding it up. It will fall down and you can't retrieve the content whatsoever.

Using stasis and try to catch it with magnetic doesn't help because stasis itself block magnetic and will just fall too fast for you to "catch" it with magnetic.

Like you, I initially had the thought of "Stasis -> Cut Rope -> Grab with Magnesis", but I found that difficult to pull off, since Magnesis has a projectile (stasis doesn't).

What I found to be easier was to use Magnesis on the chest with the rope still attached, such that it rocked back and forth. During one of the forward swings (when the chest was above the platform), I hit it with Stasis, and only then cut the rope.

This resulted in the chest landing nicely in front of me once stasis wore off. As you yourself found, this chest contains an ancient core.

Shoot the top part of the rope with a fire arrow (do not hit the rope), just the top bit which will then ignite the rope, then the rope will begin to light slowly, Magnesis the chest and when it burns, it's yours.
