Flashpoint

From Destinypedia, the Destiny wiki

A Flashpoint is a weekly challenge given by Cayde-6 in Destiny 2.

One Destination is chosen for Guardians to focus their efforts on by completing Public Events. Participating in a Public Event but not completing the objective before the timer runs out grants 7% towards the Flashpoint; completing a normal Public Event grants 15%; completing a Heroic Public Event grants 20%. Completing the Flashpoint rewards a Luminous Engram, which can drop Nightfall-quality loot.

The PvP equivalent of this activity is the weekly Call to Arms.

Unique enemies

While a Flashpoint is active at a Destination, additional enemy lieutenants appear in certain areas for brief periods, often in the middle of Public Events. Killing these enemies is entirely optional, but contributes an additional percentage towards Flashpoint completion.
