Weekly Rotation Collective Obligation

The rifle uses Primary ammo in the Energy slot. Its intrinsic, Void Leech, leeches Void debuffs, and its exotic perk, Umbral Sustenance, reloads the magazine on its own whenever you gain Devour, a Void overshield or invisibility. The catalyst adds Repulsor Brace, which gives an overshield for defeating a Void-debuffed target.

The rifle is a reward of the Vow of the Disciple raid, and it is a drop with a chance attached, which is why the lot is sold per run. Each week Bungie features two raids with farmable top-tier loot, so the raid may or may not be in that week's pair, and the runs can be done either way.

• The number of Vow of the Disciple runs you choose with the Runs counter, from 1 to 40, aimed at the Collective Obligation drop.
• The loot that drops during those runs.
• Self-play (Sherpa) as an optional extra.

• Vow of the Disciple playable on the account, which means The Witch Queen.

Does one run give the rifle?

Not necessarily. It is a drop with a chance attached, so the Runs counter sets how many attempts are made.

What does Umbral Sustenance do?

The magazine reloads automatically when you gain Devour, a Void overshield or become invisible.

What does the catalyst add?

Repulsor Brace, an overshield for defeating a target that carries a Void debuff.

Can I take part in the runs?

Yes. The order form has the extra Self-play (Sherpa) for that.
