Destiny 2 Deathless and Siren Song - how to find and defeat Takul-Dar, The Unbreakable and the Ritual Hierarch

Guide by Mat Hall Contributor

Updated on Aug. 13, 2020

Deathless and Siren Song are two mid-level Adventures you'll unlock in Destiny 2, and are available to play from the Titan planetary area once you've got about halfway through the main campaign.

Here on this page, we'll give you a rundown of exactly how to unlock and then complete the two adventures, as well as a note of what rewards you can expect for doing so.

Before diving in though, note that for more of the same, and a general overview of how Adventures work, you can take a look at our Destiny 2 Adventures hub, with a list of various other Adventures and links to their respective guides, too.

Destiny 2 - Deathless

Deathless is a mid-level Adventure, and can be found on the planet Titan.

Prerequisites: Complete Utopia main story mission.
Recommended power: 70
Reward: Rare (Blue) loot.

Here's what you need to do to complete the Deathless Adventure and tackle Takul-Dar, The Unbreakable:

Find the Knight - Just follow the waypoints.
Eliminate the Knight - You can't damage Takul-Dar, The Unbreakable until you've eliminated the Necromantis, so ignore the Knight and concentrate on that first. Once he's dead head through the gap in the coloured glass and repeat the process.

Follow the Knight.
Eliminate the Knight - Same as before. There are a lot of Corrupted Thralls in this room, so try and find a high vantage point to deal with them.
Follow the Knight - You'll eventually come to a large dark room. Ignore the dormant Shriekers on the ceiling and examine the chains blocking the door at the far end. Break the Hive Seals. The Shriekers will now spring in to life, but thankfully only one at a time. Keep some cover between you and deal with the Hive first.

End the Knight - As before, you can't do anything to him while the Necromantis alive. You should be able to take most of the minions out safely from the far end of the room - they won't run towards you if you don't get too close, and there's plenty of cover to avoid any return fire.

The Season of the Deep is here alongside the Into the Depths quest. You can know go fishing too! Don't forget to keep an eye on the Lost Sector and King's Fall challenge rotation schedule!

Destiny 2 - Siren Song

Siren Song is a mid-level Adventure, and can also be found on the planet Titan.

Prerequisites: Complete Utopia main story mission.
Recommended power: 70
Reward: Rare (Blue) loot.

Here's what you need to do to complete the Siren Song Adventure and tackle Ritual Hierarch:

Investigate Gravity Waves - Head for the three marked locations and interact with the marked area at each.

Search for the sources - Follow the waypoints.
Destroy Hive Shrine - Destroy the small metallic pillar ahead and to the left of where you entered - there's a few Hive defending it, but you can destroy it from range to avoid tangling with them if you'd prefer.

Defeat the Hierarch - This guy isn't as tough as he sounds - we took the Ritual Hierarch down with a single special attack, but a Solar (orange) energy weapon will also work.

Search for the sources.
Destroy Hive Shrine - This one is located at the top of the stairs, so you'll have to get up close and personal.
Defeat the Hierarch - Stay on the upper platform and use the pillars for cover, and this guy should be even easier than the last.
Destroy Hive Shrine - Follow the waypoints, then jump across to the platform on the far side of the hole; from here you should be able to eliminate most of the Hive below as well as taking out the Shrine - the base will just about be visible from your vantage point.

Defeat the Hive - Take out any stragglers.
Find the source - Follow some more waypoints. When you reach the room at the end some Hive will come out of hiding, so don't drop your guard. Once the coast is clear stand near the large crystal at the far end.

Stay Alive - The main threat will all enter the room through the same door you did, so we'd recommend running towards it and laying down a blanket of fire as you retreat again; the only real danger comes from the Wizards - as they can fly they may get a chance to flank you, so keep an eye out to the sides of the platform.
Defeat the Knight - He'll be preceded by a wave of Cursed Thralls, so your first order of business is to take them out before they get too close, and if you're lucky they may even cause some splash damage to the Knight. Alternatively, take the whole lot of them out in one go using a single special move!
