Crystalian bosses can get pretty annoying. These beings are made of crystals and can take a lot of punishment before breaking. The key to fighting these enemies is to hit them hard to wear them down and then take a visceral attack when they fall. However, it is much easier said than done. Like many bosses in the Elden Ring, there are a few Crystalian bosses for you to discover. This is where you can find them.
The first Crystalian boss you can come across is in the northern part of Liurnia. This is the region north of Limgrave. After reaching the lake area, head north and look at the cliff to the east of the broken bridge on the other side of Raya Lucaria Academy. Here you will find the Raya Lucaria Crystal Tunnel. The Crystalian boss fight here is just a Crystalian with a razor. Defeating this boss will give you the Smithing-Stone Miner’s Bell Bearing (1).
One of the often overlooked dungeons in the game is the Academy Crystal Tunnel. This tunnel is located in the cliffs on the western side of Raya Lucaria Academy, near where the dragon rests. This tunnel is blocked by a wall of mist and requires two Stonesword keys to access. The Crystalian boss fight is a duo fight against one with a spear and one with a staff. Defeating this boss will give you the Crystal Release sorcery.
On the east side of Caelid, near the town of Sellia, you will find a graveyard. Locate the large tomb with the magic-wielding enemy in front of it. Attack the cliff face behind the tomb to reveal Sellia’s hideout. Deep in this cave, you will face a trio of Putrid Crystalians who can apply Scarlet Rot to your character. Defeating this boss will give you the Crystal Torrent sorcery.
In the central area of the Altus Plateau is the Altus Tunnel. To get to this tunnel, you will need to go down into the forest in the center of the plateau. Once there, head inside the tunnel and head all the way to the end to find the boss. This Crystalian boss fight is another duo fight against a Crystalian with a spear and another with a knife. For defeating this boss, you will get the Hatterstone Miner’s Bell Bearing (2).
