Soak in WD-40 or stronger penetrating oils. Try again.
I recently had a very severe case and could not get it off with any penetrating stuff. Had to remove the cassette together with the freehub body and put a new freehub body on.

https://www.amazon.com/Pedros-142722.../dp/B001Q270CC expensive but worth it.
On tough ones, I have two 30" pipes; one that I slip over handle of the vise whip and the other over the wrench on the lock ring tool. With that kind of leverage, it is easy.
I purchased the vise whip after I could not get a Suntour cassette off a wheel, and my favorite bike shop broke two chain whips trying....
I haven't tried an impact wrench on the lock ring, I suspect that it would work well also.

...I continue to have very good luck with difficult to remove threaded stuff using a 50/50 mix of ATF (from the auto store) and acetone (from the paint dept at Home Depot) as the penetrating oil. You need to keep it in a bottle made from a plastic that is acetone proof..I use an old empty small TriFlow bottle. Wipe it off any rubber or plastic parts you get it on.
It's good to give it 5 or 10 minutes to soak in, then reapply a little as you start to work.
I just took apart a very old Zeus bike, and there were a number of things (fixed cup, cranks) that would not have come off intact without this stuff.

My Chain whips are made of hot rolled steel flat bar, the chain sections all join the holes in the flat bar, with the 3 piece
chain links for 1/8" chains, though the rest of the chain is derailleur chains,
It was the pins into the holes in the steel flat bar that blew out because they were 1, short ..
and 2, the links had to stretch the holes to get the pins out.. insecure thereafter,
same reason you now only shorten chains, with flush pins, like derailleur chains are now.
then I put a tube handle on it, So they're a half M + long now.
