Harbinger of Death - Swarm Nightmare Best Teams

Free to Play Team

F2P Team
Star Rail - Dan HengDan Heng Star Rail - Trailblazer (Ice)Trailblazer (Ice) Star Rail - AstaAsta Star Rail - NatashaNatasha

Dan Heng can be used as the team's Nemesis since the enemy is weak to Wind. Use the Remembrance Trailblazer and Asta's buffs to increase the damage dealt by Dan Heng.

Firefly Team

Firefly Team
Star Rail - FireflyFirefly Star Rail - FugueFugue Star Rail - The DahliaThe Dahlia Star Rail - LingshaLingsha

A Super Break team is one of the best teams against the Harbinger of Death. Firefly doesn't deal CRIT DMG, so she won't have a problem annihilating the Juvenile Sting summons without the Nemesis state.

Phainon Team

Phainon Team
Star Rail - PhainonPhainon Star Rail - SundaySunday Star Rail - CerydraCerydra Star Rail - Permansor TerraePermansor Terrae

Phainon is the best Physical DPS to use here thanks to his Enhanced State. Make sure to apply the Nemesis state on him so that he can deal CRIT DMG to enemies.

Anaxa Team

Hysilens Team
Star Rail - AnaxaAnaxa Star Rail - CyreneCyrene Star Rail - CerydraCerydra Star Rail - Permansor TerraePermansor Terrae

Anaxa can also be used here as the team's Nemesis. His ability to implant other Weaknesses makes it useful for other characters to chip down the enemy's Toughness bar.

How to Beat Harbinger of Death - Swarm Nightmare

Choose Your DPS as the Nemesis

Star Rail - Harbinger of Death - Nemesis State

The Harbinger of Death can summon Juvenile Stings with an additional effect called Rapid Evolution. This prevents your characters from dealing CRIT DMG to the Juvenile Stings.

You can select one character (their summons included), preferrably your Main DPS, as the Nemesis to have them immediately take action and ignore Rapid Evolution when attacking.

Defeat All Juvenile Sting Summons

Star Rail - Harbinger of Death - Juvenile Sting

Prioritize on taking out the Juvenile Stings to have the Harbinger of Death receive more damage.
