Defensive Microbots

The  are a new item in Risk of Rain 2. They take the form of a small, mostly spherical robot that hovers around the Survivor. This robot uses a point defense laser to shoot down incoming projectiles. It can intercept most (if not all) projectile attacks, such as Lemurian fireballs, but can be overwhelmed by large numbers of attacks, and it is incapable of stopping hitscan and melee attacks.

Despite being of Legendary rarity, Defensive Microbots cannot be obtained from Chests.
