Baldur’s Gate 3: How to Complete Sarin’s Skeleton (BG3)

Sewers are full of weird creatures in any RPG, and in Baldur’s Gate 3, there is a grease mage guarding Sarin’s Skeleton as he prepares for the final rites on the corpse. Here’s how to complete Sarin’s Skeleton in Baldur’s Gate 3.

Where to Find Sarin’s Skull in Baldur’s Gate 3

Sarin’s Skull is located northwest of Sarin’s Skeleton within the Undercity Ruins section of the sewers. This area will have a portal labeled as the “Undercity Ruins” and that makes finding the skull far easier.

You can get to the Undercity Ruins through the Lower City Sewers. Keep an eye out for the minimap, as the name of the location will change to “Undercity Ruins” if you go through the archway that’s at the coordinates X: -138 Y: 907. The Undercity Ruins door is at coordinates X: -133 Y: 934.

When you reach the portal, there will be a silent vendor waiting in front of some stairs. This also happens to be right near the Temple of Bhaal.

Sarin’s Skull is in the pack behind the silent vendor on the stairs. To get the skull, have three of your party members wait in front of the Penitent Vendor while the fourth member goes solo and steals from the pack. Sarin’s Skull will be waiting inside, and as soon as you take the skull, her headless ghost will usher you back to the casket.

As long as the vendor didn’t spot you and the ghost is moving ahead, it’s time to finish up this weird fever dream of a sewer quest.

How to Solve Sarin’s Skeleton in BG3

To fix Sarin’s Skeleton, you can go back to the casket and interact with Sarin’s casket. Make sure to place the skull in the slot that pops up and combine them as you would with any other puzzles in the game. Sarin’s ghost will be thankful and the quest is officially complete.

Sarin’s Skeleton Quest Reward:

After you place the skull, Sarin’s Ghost will reward you with an amulet that provides Innate Fortitude. This gives a character the option to react on Attack Rolls or Saving Throws with the Fortitude perk once per long rest. And getting the amulet is as simple as placing a skull.

The only part of the quest that could be considered difficult is the mage named Aelis Siryasius. Even if you managed to convince him not to attack, he will be angry when you return. Either leave a party member there when you get the skull or be ready for a fight against tons of grease elementals.

Siryasius will have an army of grease monsters, which will be somewhat tricky to beat. You’ll want to use a lot of flame attacks to end this fight very quickly. Make sure to focus on the mage himself, as all of the monsters will disappear once he’s defeated.
