Bullets are a form of ammunition fired by guns. There are currently fourteen varieties, many of which inflict debuffs on enemies.
- Although Luminite Bullets have the highest base damage of 22, Ichor Bullets inflict the Ichor debuff, lowering enemy defense by 20 and thus dealing up to 10 extra damage (15 in Expert Mode) along with its base damage of 13.
- If a player is aiming for accuracy, the best idea is to use Chlorophyte Bullets as they home in on enemies.
- Cursed Bullets can only be obtained in worlds with The Corruption as they require Cursed Flames, and Ichor Bullets can only be obtained in worlds with The Crimson as they require Ichor.
