Collect innocent essence to enter the Sentinel Base and steal the Eye of Sin.


Draining citizen

Draining the essence of a citizen.

"An excellent start. Now the Sentinel base is guarded by a protective spell which only grants access to... the pure of heart. [scoffs] Find Brother Blood's Cultists, they'll give you something to bypass the spell." — Circe
"Now, use that gem to drain essence from the innocent. Enough essence, and you can enter the Sentinel base - and steal the demonic Eye of Sin." — Circe
  • Defeat Sentinel Vanguards and steal their souls (0/5) (575 xp) (level 4)
  • Rough up civilians in the area and drain essence from the innocent (0/10) (575 xp) (level 4)
"Enough, you have all the essence you need to enter the Sentinel's base. Go there now and take what is rightfully ours!" — Circe
  • Find the Eye of Sin inside the Sentinel of Magic Base
"Just so you know, the Eye of Sin is not Trigon's actual eyeball. In case you were wondering." — Calculator


  • Vanguards are among the stronger sentinel members, being about to knock back and occasionally stun, but still fairly weak.
  • Cultist Gorge, who starts the Freelance Mission Protection Money, is just opposite the Blood Cultist.
  • Certain types of citizens always resist draining, and could only be fought. Ignore them and drain others. It appears that those citizens are used instead in Protection Money as "arrogant residents". It is possible that their arrogance prevents their essence from being pure.
  • To steal the Eye of Sin, the player must transport three flames of containment, one bright red, one dark red and one green, which are found in three side chambers. After transporting all three to their respective spots in the main chamber, interact with them to extinguish them.


  • The Flames are known as "Artifact Containment Urn" in combat messages.
