Chlorophyte Bullet

Chlorophyte Bullets are a type of late-game bullet. While expensive to create due to the use of Chlorophyte Bars and having an average base damage (10), this is offset by the ability to homing in on enemies. The homing effect is very strong. Bullets may instantly curve around to hit enemies behind the player (assuming the enemy is within the homing range of the bullets). These bullets are ideal for use when precision is required but can not be afforded: just aim in the general direction and vicinity of your target(s) and the bullets will take care of the rest.

These bullets are fairly efficient as few will be wasted (by missing) in most conditions. However, caution should be used in tight or enclosed areas: the bullets will home through solid blocks, wasting shots if an enemy is on the other side. Shots will also home in on the closest target first. If a target is killed while a bullet is tracking it, the shot will continue in a straight line like a normal bullet. Chlorophyte Bullets will not switch targets even if they are within homing range. Also note that the bullets, while having a fairly tight/small turning radius, require a reasonable amount of clearance for U-turns. Not enough clearance will result in them hitting walls, the ground, or ceilings.

A good choice of ammunition for weapons with large spread, such as the various shotgun-types or the Chain Gun. The homing effect negates the spread. These weapons are also ammunition-efficient (firing multiple bullets or offering a "Chance to Not Use Ammo"), a useful property when using such an expensive bullet.
