Outbreak

The Contamination is a post-Moon Lord Yoyo dropped by Azana's first phase with a 100% chance. When used, it fires Outbreak Darts, which inflict the Chaotic Necrosis debuff, along with the damage being increased every hit, maxing out at double damage. Additionally, it has a 16.66% (1 in 6) chance to fire a Chaos Gazer, which inflicts the Chaotic Necrosis debuff and deals 3 times the base damage.
