Beira's Pantheon

Beiria's pantheon is one of the hardest levels in Elden ring. This level takes you through the Anguish level of The Orion trail. To push through you must first get the Key of O'rathnig either by slaying him or progressing through his optional questline. After you get in, you will find a fork in the path that leads to Couple of door ways. Once you get close to the door you can hear the torturous screams of the unwanted echoing throughout the halls.

1st door-Purgatory
A blazing infernal hellhole you must dodge the traps, and weave through the spikes to get to the brief room of respite before the the boss Wraynig the Gluttonus Fool

2nd door-Greed
A hall of illusions, one misstep can lead you to your demise. You will find numerous items along you way, unlike Purgatory, though some items are "trapped," so that if you were to pick them up to would be greeted with an explosion, causing massive damage and alerting nearby enemies. Similarly to Purgatory, you can find a brief moment of respite in an empty room. Then you will have to fight Ur'kinshakur'ithein the Insatiable.

And to tie this level in to a knot, you fight the legendary Glaive Master Hodir.
