How to loosen super tight rear cassette lock ring?

The lock ring on my Shimano 11speed rear cassette is stuck. And by stuck I mean I can't undo/open the lock ring with the chain whip/cassette tool. That sucker is on there TIGHT!
Anyone have any suggestions on how I can loosen the lock ring?
Thank you.
