Theres a faster, safer, and easier way to dupe. You can do this with both paragliding or in the middle of shield surf animation. Instead of plus plus you just select your items, hit Y and B at the same time and thats it. You also wont lose any items if you mess the glitch up.
Re: shield surfing dupe, for anyone who's breaking too many shields, and/or having trouble hitting the pause button right after triggering the shield surfing action. If you already got the Zora sage, go back up to Igoshon shrine on Wellspring Is. The moon bounce effect up there gives you more air time 'cuz you go a bit higher and stay up longer. Plus, the bonus of a soft landing is real easy on shields. And if you fuse a wing onto your shield it floats even better. Run up the steps to the parts storage area and take the wings off of their shelf. Hop up there. Now you have a corner spot to help contain stuff when you drop it during the process. Heck, you can even lean one of the wings against the shelf to make a sort of low wall on that side too. One more thing others may have said already. Shields don't take damage from surfing in snow or sand. So you can do the glitch on those surfaces down on the terra firma level too.
This is not correct. In order to get them to respawn this way you have to sit by a fire, then reload your game. It’s roughly the same speed either way.
