History of Crestfallen

Crestfallen is a Supremacy triumph: in a single life, create five consecutive crests that are secured by your teammates.

How to complete

1. In Supremacy, defeated players drop a crest; a kill adds 1 point and collecting an enemy crest another. Teammates must pick up the crests from your kills.
2. Stay alive for five kills in a row whose crests are collected, so play close to teammates and let them collect.
3. Search summaries list it as Rare, added Season 4; the seal or reward is unconfirmed. Supremacy is in the Destiny Content Vault so availability depends on events.
