Ice Breaker in Destiny 2 is obtained from the Vesper’s Host dungeon. The weapon drops from the final boss, The Corrupted Puppeteer, as a random reward, so you may need several clears before it appears.

How to get it

  1. Unlock access to the Vesper’s Host dungeon.
  2. Complete the dungeon and defeat the final boss.
  3. Loot the boss chest and hope for the Ice Breaker drop.

Chances and weekly limits

  • It is not a guaranteed drop from the boss.
  • It is generally limited to one drop attempt per character each week, so running it on all three characters gives you three chances per weekly reset.
  • Completing Triumphs tied to the Vesper’s Host seal can improve your odds.

Guaranteed method

A guaranteed Ice Breaker was available for teams that cleared Vesper’s Host in contest mode during the dungeon’s launch window. If that window is already over, the normal boss-drop route is the way most players get it now.

Catalyst note

The catalyst is earned separately through the dungeon’s secret puzzle steps and related objectives, not from the initial weapon drop.

TL;DR: run Vesper’s Host, beat the final boss, and keep farming weekly on each character until Ice Breaker drops.
