Parasitism

Overview

Parasitism is a Season 6 trait on the exotic Outbreak Perfected pulse rifle. Its bonus scales with how many SIVA nanites are attached to an enemy. More attached nanites means more damage.

Mechanics

Damage keeps rising the longer you fire at an infected target, up to a threshold. It also increases as more players use the weapon on the same target, so the perk is strongest in team fights against a single high-health enemy.

As of 2019, a kill generated nine nanites at about 10 to 11 damage each, with extra damage against afflicted enemies. Later patches may have changed these values.
