History of Ephemeral Arsenal

Overview

Ephemeral Arsenal is a Triumph in Destiny 2 that asks you to collect all of the volatile weapon mods offered during one Arms Week. It is tied to the Sharpshooter title. Each Arms Week offers three volatile mods, and the set changes every event.

The objectives in the triumph record are Shattershafts, Tungsten Bowstring and Jumpshot. These were the volatile bow mods of Arms Week III (January 27 to February 3, 2026), which focused on combat bows. Other weeks feature different mods.

How to complete

1. Go to the Shooting Range and talk to Ada-1 during Arms Week.
2. Start the introduction quest. Each later mod quest asks for kills with that week's featured weapon type.
3. Collect all three mods within the same Arms Week. Mods expire when the event ends, so a missed quest means you restart when Arms Week returns.
4. Once all three mods are collected, the triumph completes. Most players need about half an hour for the quests.

Tip: Plan the quest order before starting, because a failed quest costs the whole week's progress.

Rewards

No separate reward is listed for this triumph. It counts toward the Sharpshooter title.
