Modifier

Modifiers are similar to Skulls from the Halo games, in that they make story missions and strikes more challenging by adding a new level of difficulty. Modifiers are typically randomly applied for special missions. Modifiers can be applied to normal Story missions by changing the difficulty and raising the level of the mission.

Mission-specific modifiers

 * Heroic: Enemies are more numerous and aggressive. All missions above their default level have Heroic active. Heroic is also used in the Daily Heroic Story Mission and Weekly Heroic Strike.
 * Epic: Heavily shielded and highly aggressive enemies appear in large numbers. Epic is always active during the Nightfall Strike.
 * Nightfall: On death, you are returned to orbit. Nightfall is always active during the Nightfall Strike.

Randomly selected modifiers

 * Angry: Enemies do not flinch, even after taking massive damage.
 * Arc Burn: All sources of arc damage deal more damage.
 * Juggler: Enemies only drop ammo for weapons you are not currently using.
 * Lightswitch: Enemies deal more melee damage.
 * Solar Burn: All sources of solar damage deal more damage.
 * Void Burn: All sources of void damage deal more damage.
