While roaming around the Lower City Sewers in Baldur’s Gate 3, you will come across a rather unstable mage named Aelis Siryasius. After you encounter him, you will need to make a critical decision — to kill or not to kill him. Here is a detailed guide to help you make an informed decision:
Should You Kill Aelis?
Aelis Siryasius is a half-elf drow NPC in Baldur’s Gate 3 who is known for his Grease-based Elementals and unstable nature. When you first meet him in the Lower City Sewers, he will mistake you for a member of the Absolute. If you manage to convince him otherwise, you will earn his temporary tolerance.
However, regardless of what you do, Aelis will eventually turn hostile, forcing you to determine his fate: to kill or not to kill.
Killing Aelis Siryasius
You will notice that Aelis becomes hostile on your return, regardless of previous interactions. If you decide to kill him, it will grant you an easy access to valuable treasures in his den such as Cindermoth Cloak, Quarterstaff +2, Scorched Book, and Incomplete Journal. Additionally, killing Aelis Siryasius solves the Sarin’s Skeleton puzzle.
While trying to kill him, focus on dealing damage strategically, possibly using Sleep Spells to manage the encounter. Also, consider taking early hits against him (and his Elementals) during the temporary ‘Tolerance’ period.
Not Killing Aelis Siryasius
While the game does not present grave consequences for killing Aelis, you can choose to spare him if you are on a ‘Pacifist’ playthrough or simply because of personal ethics. Here is how you can do it:
You can toggle on non-lethal attacks to subdue Aelis without killing him. Alternatively, you can use Invisibility Spells (or Potions) to bypass Aelis without confrontation.
