• Bullets gain random bullet effects and can travel at differing velocities. The chances for all effects are listed below. Bounce: 10%
• Pierce: 10% Chaos Bullets will continue attempting to stack bounces and pierces onto a bullet until it fails, or reaches 10 bouncing/piercing. This means that a projectile that already gained a bounce has another 10% chance to gain an additional bounce, and then another 10% chance to gain a third, etc.
• For each additional application of piercing, Chaos Bullets will pierce two more enemies, while for each additional application of bouncing Chaos Bullets will only bounce one extra time.
• [Fat Bullets] (between 25% and 75% above normal size): 10% Unlike with the actual [Fat Bullets] item, the fat bullets effect on Chaos Bullets only affects bullet size, and not damage.
• There is an additional 10% chance to select from the weighted table below:

• Kaliber's Grip - If the player has [Abyssal Tentacle] , [Abyssal Tentacle] grabs two enemies at a time.
• Bullets can gain multiple effects. This is more likely when using items like [Ring of Triggers] .
• Considering this item causes fired bullets to travel at random velocities, it is recommended to drop it before attempting [Winchester] 's game in order to be able to time shots properly.
• If duplicates of this item are somehow obtained, further increases the chance of bullets having a random effect and allows multiple effects to appear on a single bullet.
