Link high diffs. He can auto build a gloom rock that one shots silver boss bokoblins, which are one of the two enemies (along with Captain Construct IVs) that can’t be one shot with a silver lynel saber horn eightfold blade sneakstrike. And if he uses Sidon’s water shield he can literally shake off an attack like it’s nothing. Also he has the ability to pause, eat a three course meal, and continue fighting. Also glitches are allowed
Basically Toki and Jabra fighting Zoro for Ocarina and Twilight, but you do know that Link can eat an entire plated meal while in the middle of a fight
Bullet time also slows time, which still wouldn't matter as Zoro is FTL so he'd hit anyways
You can only have up to 4 fairies at once in your inventory, so Link can only survive 5 hits, which will take less than a millisecond for Zoro to dish out
