• Doubles the player's bullets and causes them to travel in a helix pattern. Each bullet deals 66% of its original damage, for a net 32% increase in damage.

• Double Double Helix - If the player also has [Helix] , instead of the [Helix] Bullets effect being applied to each bullet, [Helix] 's projectiles will be doubled (2 bullets will fire on each side while following the original pattern), damage is increased by 25%, and shot speed is increased by 50%.
• Dualing Pistol - If the player also has [Dueling Pistol] , it gains homing and changes appearance.
• One Fish Two Fish - If the player also has [Barrel] , [Barrel] will fire a red fish that sets enemies on fire and a normal blue fish.
• Explosion damage will not be affected by damage modifiers, including damage reduction. As such, [Helix] Bullets will massively buff explosive weapons.
• This item has a negative effect with guns that fire homing projectiles such as [Bullet Bore] or [Com4nd0] , causing them to lose homing. If the player also has [Shadow Bullets] , the shadow projectiles will retain homing.
• This item does not affect shots fired from other guns with [Chance Bullets] .
• When used by a gun that fires several different kinds of shots at random, such as [Mr. Accretion Jr.] or [Tetrominator] , each bullet of the helix will be randomly selected. An notable exception to this is the [Dark Marker] with the Antichamber synergy, whose shots are guaranteed to be one red and one blue. This makes triggering the blank effect extremely easy.
• If bullets are reflected by [Casey] with this item, the bullets will fly in a helix pattern but will not double.
• When using [Remote Bullets] , the helical bullet path will remain even as bullets curve towards the cursor.
• This item applies to bullets fired via passive items such as the [Orange Guon Stone] .
• This item makes [Winchester] 's game nearly impossible to win, as the helix modifier makes it so the shots don't go in a straight line. The item cannot be dropped after paying [Winchester] , so make sure to drop it ahead of time.
• The item also affects projectiles of some familiars.
• With [Scattershot] , if [Scattershot] is picked up before [Helix] Bullets, four times the normal amount of projectiles are fired. However, if [Helix] Bullets is picked up first, six times the amount of projectiles are fired. Regardless of the amount of bullets fired with [Scattershot] and [Helix] Bullets, each bullet does 36% of its original damage.
• If the player has [Flak Bullets] , the smaller bullets will not travel in a helix pattern.
• [Helix] Bullets only partially affect the final projectile of [Zorgun] , causing it to move in a helix pattern but not duplicate.
• When used by a gun with nonzero spread, each shot's deviation will be mirrored between the two bullets.
• Bullets will no longer be affected by the gravitational pull of the [Black Hole Gun] , nor the [Singularity] .
• If the player has [Hip Holster] , the projectile upon reload will move in a helix pattern, but not duplicate.
• This item causes shots fired by [High Kaliber] to appear in front of the player when they hit their target.
• When paired with the boost from [Macho Brace] , occasionally only one of the [Helix] Bullet's projectiles will be fired, resulting in a loss in damage. It is unkown what causes this bug.
