Follow our expert walkthrough for Diablo IV's Depths of Despair quest. Learn how to start, exorcise Kvera's husband, and defeat the demon Demotath for rewards.
Alright, so you're ready to tackle the Depths of Despair quest in Diablo IV? This one's the second part of the Malady of the Soul questline, so make sure you've wrapped that up first. Once it's done, just head away from Kyovashad for a bit, and this quest should pop up. Your first stop is to find Sister Octavia; she's hanging out on the eastern edge of Kyovashad. Go have a chat with her to get the ball rolling.
- 1
Talk to Sister Octavia: She'll fill you in on the situation. Apparently, another Kyovashad resident, Kvera's husband Vasek, has fallen prey to demonic possession. Yep, you guessed it – Sister Octavia needs your help with another exorcism.
- 2
Enter the Ominous Cellar: After the initial chat, head into the house where Vasek is being held. Inside, you'll find an Ominous Cellar. Go on in and prepare to smite some Carvers. Don't get too comfortable though, because Vasek has managed to escape!
- 3
Find Vasek in the Sewers: Leave the cellar and talk to Kvera again. She'll point you in the right direction. Follow the blood trail through the streets – it'll lead you to the entrance of Kyovashad's Sewers. Be warned, these sewers are massive and, as expected for a video game, absolutely crawling with demons and nasty critters. Seriously, you have to wonder if the city's demon problem is just a side effect of this sewer situation!
- 4
Reach the Wastewater Basin: Your main goal here is to track down Vasek. He's going to lead you on a wild goose chase through the sewers, so don't expect to catch him right away. Just focus on clearing out the enemies as you push through until you reach a suspiciously arena-shaped chamber called the Wastewater Basin.
- 5
The Ritual and the Boss Fight: You'll find Vasek cornered here. Sister Octavia will step in to place her chalice and begin the ritual. Unfortunately, this one doesn't have a happy ending. You'll have to face a demon named Demotath.
- 6
Defeat Demotath: This guy is a hulking, winged monstrosity, kind of like a giant Oppressor with a huge axe. He looks pretty imposing, but honestly, he's surprisingly fragile for his size. His axe swings can pack a punch, and he can inflict the Vulnerable debuff, so watch out for those repeated hits. Since he's an elite enemy, he also has the Frozen and Chilling Wind traits. The Chilling Wind part means he'll periodically summon frigid torrents, but don't worry, these are pretty well telegraphed and easy to dodge.
- 7
Complete the Quest: Once you've defeated Demotath, the demon will taunt you for failing to stop him. Then, you'll need to escort an injured Sister Octavia out of the sewers. Once you're both safely outside, talk to her to wrap up the quest. You'll earn a Cache, plus a good chunk of XP and gold.
- Keep an eye on Demotath's axe swings, especially since he can inflict the Vulnerable debuff. Dodging is key here.
- The Chilling Wind ability from Demotath is easy to avoid if you watch for the visual cues.
- Don't get too bogged down in the sewers; your main objective is to reach the Wastewater Basin.
- Cache
- XP
- Gold
