Defensive Microbots

 are a new item in Risk of Rain 2. It intercepts and destroys incoming projectiles, such as Lemurian fireballs. Hitscan attacks, like Lesser Wisp shots or Stone Golem lasers, cannot be blocked by Defensive Microbots regardless of the distance between the item holder and the attacker.

Despite being of Legendary rarity, Defensive Microbots cannot be found in Chests, traded for using Cauldrons or 3D Printers, or obtained through any other typical method. They are near-exclusive to the Captain, who is granted one due to his passive skill of the same name.
