History of Crater Spark

Crater Spark is a Season of the Undying (Season 8) triumph: defeat combatants on Earth's Moon using Arc abilities. It is one of the "hard mode" triumphs for the Undying title, and is not obtainable now as seasonal content.

How to complete

1. Per GameRant, it covers Arc melee, grenade and super kills on the Moon. Search summaries give counts of 300 melee, 400 grenade and 300 super kills; unconfirmed here.
2. Use supers as soon as they are charged and spam Arc grenades since they recharge fast.
3. Regular melee kills may not register; Bungie forum users report that charged melee kills count, and that hitting with the hilt of an Arc sword with no ammo works reliably.

Reward unconfirmed beyond contributing to the Undying title.
