This happened to me on a honda civic head. A great mechanic somehow drilled from the reverse side and got it out. I don't pretend to know the process but he mentioned heat and patience. It is definitely a job for an expert if one is available and affordable. Sometimes it is possible to chase the entire mess out with careful use of a chisel, heat, liquid wrench, time--again one of those careful jobs which will sell you on the mechanic for life.
Of course if any of the stud remains above ground, you have shot at clamping it with visegrips and working at it CAREFULLY.
Either way remember, you got into trouble in the first place expecting to wrench it out in one step. This is never happening. If it gets soaked enough, expanded enough eventually it will budge. Just budge. Then budge it back. More liquid wrench. More patience. After a while it will come. Then if you do it yourself you will burst a button with pride!

EDM is best, but if unavailable you have a tough job in front of you. It also depends on the material the stud is in, you might be able to grind an edge on the stud if enough sticks out and heat the area around the stud and use a punch to back out the stud. Cutting tool steel is not easy.

sounds silly but years of work as a machinist proves this true. Get a parafin candle. The candle absolutely must be 100% paraffin. Heat the metal AROUND the broken screw extractor and then lock onto it with vise grips as tight as you can and SLOWLY turn the nut and broken extractor out. DO THIS SLOWLY AND HEAT AROUND THE BROKEN STUD AND EXTRACTOR NOT THE BROKEN PARTS.

Eewww! You aren't supposed to do that. What is the stud part of? How accessible is it ? What type of extractor is it?
Some can be removed by grasping with needle nosed pliers, others you might heat red let cool and drill out. Gonna be tough, glad it's you and not me.

i own a shop ,and that's going to be a hard one to get out of there since the extractor is harder than most drill bits this may have to be cut out of it, i did this not long ago,and it took hours of heating and drilling to get it out,but it did come out,is it in something that you can cut off or is in a recessed area,if it a recessed area and you cant afford to damage it,the only thing i know of that will get it out is a diamond bit,and there about 25 bucks just for one bit,but that will get it out,good luck with it,i know you got your hands full on this one.

Yeah, drill out and start over....by a dozen 1/8 inch titanium bits then you can step the size up, so that way you can just keep wearing through them.
