Defeat Plaudia the Bizarre Vermin

The First Descendant - Defeat Plaudia the Bizarre Vermin

Kill all enemies in the last zone of the Seed Vault to summon the final boss, Plaudia the Bizarre Vermin. She spits out poisonous goo and occasionally spawns toxic slime on the ground, which when stepped on, applies a poison effect on your character. Make sure to avoid these when fighting her!

Avoid Stepping on the Green Slime

The First Descendant - Plaudia Green Slime

Plaudia has an AoE ability where she summons multiple green circular slime on the ground, which can poison your character when caught in it. You can easily avoid these as the ground will be outlined with a green circle, indicating that a green slime explosion will occur in that area.

Defeat Enemies Connected to a White Line to Remove Invulnerability

The First Descendant - Plaudia White Lines

Each time Plaudia's health bar is reduced to zero, she will call upon several enemies connected to her via a white line which grants her immunity to all forms of damage. Kill all the minions that are linked to her to cancel out her invulnerability.
