Season of the Risen

How to get Collective Obligation (Exotic Pulse Rifle) Plus Void Builds in Destiny 2

Collective Obligation is the new Exotic Pulse Rifle from the Vow of the Disciple Raid which launched with the Witch Queen Expansion. This one may not instantly seem as overpowered as Vex Mythoclast, but I think people are going to love this exotic weapon with a little time with it. This weapon works so well with Void 3.0, and today I am going to look at the stats and the perks, how to get the weapon, plus how to make it effective with Void 3.0 builds.

One of the best parts of the Witch Queen expansion has been the Void 3.0 update, and the Collective Obligation works hand in hand with that update. Given we have all the aspects and the fragments that go with Void, plus you can get access to all of that instantly when you start up the Witch Queen Campaign already makes this better than the process we had to go through (and some of us are still going through) with Stasis.

Collective Obligation

Collective Obligation is an Exotic Energy Pulse Rifle. Looking at the stats we have Impact 29, Range 54, Stability 60, Handling 47, Reload Speed 47, Rounds Per Minute 390 and Magazine 36.

  • Void Leech – This weapon leeches Void debuffs when damaging targets that are suppressed, weakened, or volatile. Once charged, [Alternate Weapon Action] to swap firing modes. In this mode, damage from this weapon applies the same Void debuffs that were leeched.
  • Umbral Sustenance – This weapon’s magazine is automatically reloaded when you gain Devour, a Void overshield, or become invisible.

The Collective Obligation manages to create unique playstyles which allow you to build around the Void buffs and debuffs. With Collective Obligation you can essentially have many of the buffs and debuffs active at the same time, as long as you keep an eye on the timers and use Collective Obligation effectively.

Void Leech is the key here. This makes it one of the most unique, and also one of th emost effective Exotic weapons out there. Here’s a quick reminder of some of the Void 3.0 keywords to take note of when using Collective Obligation.

  • Suppress – The target is taken out of any active ability when suppressed. While suppressed, the target cannot activate any abilities or movement modes. Combatants are disoriented.
  • Weaken – The target takes increased damage, has slowed movement, and is disoriented.
  • Volatile – The target will explode in a Void detonation upon taking additional damage. If the target dies before volatile has taken enough damage to detonate, the detonation happens anyway.

Take Supress as an example. In Void 3.0 you have Suppression grenades, you can throw them and suppress your target, which means they are disorientated. Once you have hit an enemy with a Suppression Grenade, then you can leech this effect, or essentially transfer this effect from the battlefield, into your weapon, and they spray this effect with the Collective Obligation, further using the supression to your advantage.

This gets even better when you combine mods with this Exotic weapon, for example Supressive Darkness. This is an artifact mod in Season of the Risen, and the description reads “Whenever you suppress a combatant, you also weaken them, causing them to take additional damage for a short time”. We are applying two Void 3.0 effects or keywords here, and when you use the Collective Obligation with this mod and Supression Grenades, then you are weakening enemies too, plu your are spreading this effect with the weapon by leeching the effect and using the alternate firing mode. It’s going to take a little practice, but once you get your head around how this weapon works, then it’s very potent, and I think in time it’s going to be a very sought after weapon.

How to get Collective Obligation

To get this Exotic Pulse Rifle you have to run the Vow of the Disciple raid, and it’s a random drop from the final boss. This is the only place you can get it, and if it’s like other raids then you have an approx 5% chance at getting it. To maxmise your chances, you can run three characters per week, that way you’ll have multiple chance per week to get it to drop for you. To run the raid you’ll need access to the Witch Queen expansion, and you’ll have to find 5 other Guardians. You can either get some friends together, run with some clanmates, or you can find other Guardians via LFG apps or forums. I recommend using the Bungie app, that’s available for iOS, Android or via

Collective Obligation and Warlock Void build

Exotic Armour

I’m using Nezarec’s Sin, one of the best Warlock Exotic armour pieces around. Nezarec’s Sin is an Exotic Warlock Helmet and it comes with the perk Abyssal Extractors – Void-damage kills increase ability energy recharge rate. You can get this as a random exotic drop, or from Xur when he’s selling it.

Subclass – Void

Grenades – Suppression Grenades

Aspects – Child of the Old Gods (rifts create Void Souls that weaken enemies they latch on), Feed the Void (Void ability kills activate Devour, which heals player with each kill). Feed the Void is going to be good here because this is going to activate our perk Umbral Sustenance – Magazine is automatically reloaded when you gain Devour.

Fragments – You can use pretty much any combination of fragments, but one you defintely want to be using is called Echo of Undermining (grenades weaken enemies). Using this in combination with Supression Grenades, means you’ll be able to leech Suppression and Weaken at the same time, and then use that as a weapon via Collective Obligation to suppress and weaken multiple enemies at the same time.


Font of Might – Picking up an elemental well that matches your subclass element grants a temporary bonus to weapon damage.

Elemental Ordnance – Defeating a combat with a grenade Spawns an Elemental Well that matches your subclass energy

Volatile Flow – Picking up an Elemental Well grants your Void weapons Volatile Rounds

Energy Vampirism – Gain energy for your least charged ability when you supress a target.

Bountiful Wells – Elemental well mods that cause you to spawn elemental wells can now stack, spawning additional wells for each additional copy of the mod you have equipped.


I’m using a combination of grenades and fragments to supress and weaken targets. However, there’s another way to do this too through a seasonal mod called Suppressive Darkness.

Suppressive Darkness – Whenever you suppress a combatant, you also weaken them, causing them to take additional damage for a short time.

Therefore, if you want to use another fragment that isn’t Echo of Undermining (grenades weaken enemies), then you could use Suppressive Darkness instead. The only thing with doing this is there’s no guarantee it’s going to be around next season.

I’ve heard a bunch of people saying they are underwhelmed by Collective Obligation, but I think it’s very good and it’s a great showcase for the new 3.0 subclass type and how they can work with exotic weapons. I hope we see more of this in the future, especially with Arc and Solar on the horizon.

Let me know in the comments what you think of Collective Obligation and let mw know your top builds.
