Crystalian bosses can get pretty boring. These beings are made of crystals and can take many punishments before they shatter. The key to fighting these enemies is to hit them hard to wear them down, then take a visceral attack when they fall. It’s much easier said than done, however. Like many bosses in Elden Ring, there are a few crystal bosses to discover. Here’s where you can find them.
The first crystal boss you might encounter is in the northern part of Liurnia. This is the region north of Limgrave. After arriving in the lake area, head north and find the cliff east of the broken bridge on the other side of the Raya Lucaria Academy. Here you will find the Raya Lucaria Crystal Tunnel. The Crystalian boss fight here is just a Crystalian with a ringblade. Defeating this boss will grant you the Smithing-Stone Miner’s Bell Roll (1).
One of the often overlooked dungeons in the game is the Academy Crystal Tunnel. This tunnel is located in the cliffs on the west side of Raya Lucaria Academy near where the dragon is resting. This tunnel is blocked by a wall of fog 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. Beating this boss will give you the sorcery Crystal Release.
On the east side of Caelid, near the town of Sellia, you will find a cemetery. Locate the large tomb with the magical enemy in front of it. Attack the cliff behind the tomb to reveal the Sellia Hideaway. Deep within this cave, you’ll face off against 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 center of the Altus Plateau is the Altus Tunnel. To reach this tunnel, you will need to descend into the forest in the center of the plateau. Once there, head inside the tunnel and head towards the end to find the boss. This Crystalian boss fight is another duo fight against one Crystalian with a spear and another with a ringblade. For defeating this boss, you will get the Somberstone Miner’s Bell Bearing (2).
