The Putrid Crystalian Trio of Sellia Hideaway is widely considered one of the most brutally demanding boss fights in Elden Ring, as Tarnished must face three Rot-inflicting Crystalians all at once. While many will recognize bosses such as Malenia and Maliketh as exceedingly challenging, their mechanics are learnable and can be defeated through perseverance or even cheesing. On the other hand, the battle with the Putrid Crystalian Trio is ruthless, forcing players to handle three Elden Ring bosses simultaneously within a small enclosure.
To find the three Putrid Crystalians in Elden Ring, Tarnished must reach the end of Sellia Hideaway, a Dungeon hidden behind an Illusory Wall northeast of the Church of the Plague in Caelid. Players can get to this location by either completing Sellia's Magic Barrier Puzzle or falling from the ridge south of Fort Faroth. Within this area, Elden Ring fans will encounter a graveyard. If they strike the cliff wall directly north of the largest tomb monument, they will discover the secret entrance to Sellia Hideaway.
