I was in a PK game last night and a zon had one of those rings on. He just sat outside of town and let me hit him with every attack possible (SORC) His health did not even drop AT ALL. First I tried with 10 light skill charms and nova/ts and then with 10 cold skill charms and orb. My skills were close to 50 when I used them. Even tried a meteor and firewall/hydra. NO DAMAGE. I think I'm done with DII. Now the only decision is what to do with the 11 UNID WF I have been saving for trading.
