History of Break the Glass

How to complete

Defeat combatants with grenade abilities while playing the strike "The Glassway" on Europa (Destiny 2: Beyond Light). Only kills made inside that strike count, so launch it from the Vanguard strike playlist or directly.

• Build around grenades: use aspects, fragments and mods that speed up grenade recharge so you can throw one every few seconds.
• The strike is full of crowds to throw into: Fallen Dregs, Vandals and Shanks in the icy canyon and Nexus, then Vex Goblins, Hobgoblins and Minotaurs in the Glasshouse and boss area. Aim at groups rather than bosses.
• The fluid-draining section and the final fight against Belmon spawn waves of adds, which are the best places to farm kills.
• Progress is cumulative, so it can be finished across several runs.

Category and reward

The game text lists no reward, and none of the pages I opened say which seal or category it belongs to. The kill count is also not stated in them; check the in-game triumph.
