"Electricity resistance," Link says. So not that different from the Fireproof elixirs, really. They just had a less descriptive name.

As for how much Link had brought...

"Everything." He says this casually, as if it's no big deal that he's carrying around an entire storehouse worth of ingredients. Though he does pause, thinking for a moment, before adding: "...That I have back."

So not everything everything. But he hadn't left anything that he'd recovered behind.
