Read full thread. Secret hardcore in game item. Anyone who gets the Badge of Perseverance properly can join the Pantheon of Grim Gods. I was first but did it twinked just for the achievement so I took the title as Hades. Under Zeus but has that bad ass factor and fits my devil motif.
Contragor gets Zeus for world first untwinked which is the hardest way to do it, he also took the hardest required boss path at the end as I did. Caius is Poseidon for following the path, so a brother of Zeus is appropriate.
So far as we know only us 3 have legitimately obtained it.
