Default Oh God no

I was drilling a pilot hole through 1" plate and the drill bit snapped around 9/10 the way down and it broke off beneath the surface.

Can someone aware me just how much misery I'm in for trying to extract it?

my current thinking is to hit it with a torch then let it cool slowly to remove some of the hardness from it. then I can maybe drill it out with another bit

or maybe a screw extractor?

try to make one of these? https://www.amazon.ca/Extractor-Brok...dp/B07KGBBD6W/

Locate the point that you drilled from on the other side of the plate. Use a larger drill for a pilot on this side. Drill the hole through from the reverse side with the larger pilot size and when you break through, take a pin punch and drift it out.

Since it looks easy to locate from the back, that is the obvious way to do it.
