Not too long back I posted about reaching a useless ledge from BSmith screen with a combination of Fire Rod Boost, dash slide and stopping the dash with a well timed bomb explosion.
I later realized you could probably do the same at Lorule BSmith.
Indeed you can.
I think it's bit harder though. Kinda.
You first Fire Boost (Or bomb boost, if you're into that) yourself on the fence to the right of BSmith.
Then, you throw a bomb on this ledge, and fairly quickly dash slide across.
The bomb needs to detonate at a correct time to stop your dash before you slide into the moat (Which is at least close to a softlock)
This is for the Hyrule one. Here, I'm not sure if the fence is shorter or what, but I didn't get the dash slide here, so I had to walk one screen north on top of the fence for it. The reason the dash slide is a bit trickier is that you can't just go to the end of the fence and start a dash. You need to actually find a decent spot for it.
On the other hand, it's easier because if you successfully dash slide, but the bomb detonates late, you'll fall into the hole instead, and spawn back at the fence. That's a stark contrast to nigh softlock from the Hyrule one.
Again, this is beautifully useless as far as I can tell, but hey, it's something.
