Velocity

Velocity is the speed of a projectile fired from a weapon. (Not to be confused with the speed stat listed for weapons in game, which is actually its use time. The speed given for an item in-game (i.e. fast, average, slow) has no correlation with the item's velocity. The higher the weapon's velocity, the faster the projectile travels, and the sooner it will hit its target, hence higher velocity weapons/ammo will reduce the need for aiming shots ahead of a moving target in order to hit them. This is an advantage that may prove very useful when fighting fast-moving enemies or when attacking from a large distance away.

Since the velocity of different weapons and ammo are not provided while playing, here are some basic guidelines to follow when considering the velocity of a certain item:
 * Weapons that use arrows generally have lower velocities than bullet firing weapons.
 * Ranged Modifiers also affect a weapon's velocity.
 * Some weapons don't have a consistent velocity. For example, the Demon Scythe fires a projectile with an exponentially increasing amount of velocity. In addition, the Magical Harp's note projectiles have a velocity based upon how far from the player you click when using it. Furthermore, the Cursed Flames projectiles increase in velocity every time they bounce.

It should be noted that many projectiles have a sudden and significant decrease in velocity when impacting liquids such as water. Some projectiles, especially flame-related ones, are even immediately destroyed upon impacting water. In the case of most projectiles, there is a "lifespan" that causes the projectile to disappear after a certain period of time has passed, regardless of the distance traveled by the projectile. This means that liquids can significantly reduce the effective range of a weapon against enemies submerged in a large expanse water.

It should also be noted that bullets, some magic projectiles, and a few others aren't affected by gravity, and will maintain their trajectory and velocity when shooting upwards as opposed to slowing down and eventually falling. This is a major advantage when firing at airborne enemies or across long distances.
