Radiant

Radiant is a Solar buff in Destiny 2. While it is active, your weapons deal increased damage to combatants, and they pierce the shields of Barrier Champions and stun them.

The Hunter's Acrobat's Dodge is the main source of Radiant. Reports differ on whether the buff applies only to the Hunter or to nearby allies and enemies as well. Radiant also appears in armor set bonuses: Apostate's Blade scorches the target with melee hits while you are under Radiant, Restoration or Cure, and Collective Psyche increases the duration of Radiant effects applied to you.
