Somewhere in the Last City, a Hunter is crying into a bowl of spicy ramen because a certain Rhulk has once again refused to drop the shiny toy. That toy is Collective Obligation, a Void Exotic Pulse Rifle that entered Destiny 2 with The Witch Queen expansion. It lives in the Energy slot and looks like it was designed by a committee of very serious architects. Guardians who want it cannot simply visit a kiosk. They must assemble a fireteam, learn several raid mechanics, and then pray to the RNG gods.

The Long, RNG-Filled Road to Ownership

Obtaining Collective Obligation is less about skill and more about patience. The gun drops randomly from the final reward chest in the Vow of the Disciple raid. To reach that chest, a fireteam must clear every encounter and defeat Rhulk, a boss who enjoys kicking Guardians off platforms. That is the entire raid, not a quick strike. Because the drop is pure RNG, some players have seen it on their first clear while others have turned into permanent residents of the raid.

Clever raiders can improve their odds by running the raid on multiple characters each week. Unfortunately, that also means watching Rhulk do his dramatic final stand multiple times. The steps are simple on paper:

  • Complete Vow of the Disciple from start to finish

  • Defeat Rhulk in the final encounter

  • Open the final reward chest

  • Cross every finger, toe, and Ghost shell

No amount of wishful thinking changes the drop rate. The game does not care how many times a Guardian has fallen off the platform. It only cares about the roll of the dice.

The Perk Package: Simple on Paper, Spicy in Practice

For all the effort, Collective Obligation arrives with a curated roll that is honestly rather tidy. A table helps keep the shiny details straight:

Slot Perk What It Does
Barrel Arrowhead Brake Increases handling speed and greatly controls recoil
Magazine Flared Magwell Greatly increases reload speed and slightly increases stability
Stock Hand-Laid Stock Further increases stability

The real star, however, is the unique perk combo. The Exotic Perk Umbral Sustenance makes the magazine automatically reload whenever a Guardian gains Devour, a Void overshield, or invisibility. That is already lovely. Then comes the Intrinsic Trait Void Leech. The gun absorbs Void debuffs when damaging targets that are suppressed, weakened, or volatile. Once charged, a Guardian can use the Alternate Weapon Action to swap firing modes. Subsequent shots then apply the same Void debuffs that were leeched.

In plain terms, the gun sees an enemy being made miserable by Void. It takes notes. Then it makes other enemies miserable in exactly the same way.

Who Loves This Gun Most?

Every Void-flavored Guardian has a reason to smile. Hunters can tap into invisibility almost on demand, which means free reloads for days. Warlocks chewing on Devour will watch the magazine refill while they heal. Titans slapping down Void overshields turn the gun into a well-oiled machine. A coordinated fireteam can apply weakened, suppressed, and volatile effects so the Pulse Rifle has a full buffet of debuffs to steal.

It is even better when someone else handles the debuffing. One fireteam member can weaken a champion, another can suppress a major, and the Collective Obligation user can simply go to work. The weapon shines in endgame content where controlling enemies is more valuable than raw damage.

Is It Worth the Headache?

Yes, mostly. The road to ownership is paved with repeated Rhulk encounters and a fair amount of mild rage. But Collective Obligation is one of the more intricately designed Exotic weapons in Destiny 2. It rewards map awareness and Void build synergy rather than just aiming at a big crit spot. As of 2026, Void shenanigans remain a favorite pastime, and this pulse rifle still finds a home in many loadouts. It will not carry a terrible player, but it will make a decent one feel like a debuff-spreading space wizard.

Eventually, with enough practice and a patient fireteam, a Guardian will stand in front of that final chest, hold their breath, and see the sleek pulse rifle drop. That is the moment the ramen gets cold and the celebration begins.
