Velocity is a hidden statistic that determines the travel speed of a projectile fired from a weapon. It is not to be confused with use time, which is the delay between subsequent uses of an item (e.g. "Fast", "Average", "Slow"). The higher the weapon's velocity, the faster the projectile travels, and the less the player will need to "lead" shots ahead of a moving target. This is an advantage that may prove very useful when fighting fast-moving enemies or when attacking from a long distance.

## 目录

### Effective Velocity

For weapons with a specific associated projectile, the multiplier effect is automatically calculated and displayed as Effective Velocity.

### Velocity Multiplier

For ammo items, the multiplier is displayed alone as Velocity Multiplier.

To determine the total Effective Velocity of a weapon firing a particular type of ammo, add the weapon and ammo velocities together, then multiply the result by the Velocity Multiplier.

Example: Firing Ichor Arrows from an Ice Bow:

• Ice Bow's velocity = 10
• Ichor Arrow's velocity = 4.25
• Ichor Arrow's Velocity Multiplier = 2
`(10 + 4.25) * 2 = 28.5`

The total effective velocity when firing an Ichor Arrow from an Ice Bow is 28.5.

### Internal equation

"extraUpdates" counts from zero, which indicates no multiplier (the value for most projectiles). 1 extra update means a ×2 multiplier, 2 means a ×3 multiplier, etc.

As a general rule, extra updates are applied last in the formula determining the projectile's velocity, after the sum of projectile and weapon velocity:

`totalEffectiveVelocity = (weaponVelocity + projectileVelocity) * (projectileExtraUpdates + 1)`

The Magic Quiver sets the "extra updates" value of arrows with a value of less than `1` to `1`, which essentially doubles arrow speed (if the original "extra updates" value was `0`, like in most cases), but does not affect arrows like the Venom Arrow, which have an "extra updates" value of `1` or greater.

For beam weapons such as the Shadowbeam Staff, "extra updates" will also determine the length of the beam. The length in this case is calculated by multiplying projectile velocity by the extra updates multiplier.

## 小贴士

• 使用的武器的射速通常要低于发射子弹的武器。
• 某些远程修饰语会影响武器的射速。
• 一些武器（通常是魔法武器）没有固定的射速。
• 恶魔锄刀会发射射速逐渐增加的射弹。
• 死神镰刀的射弹和恶魔锄刀相反——发射的射弹有指数下降的射速，直到消失前停在原地。
• 魔法竖琴的音符射弹的射速会根据玩家与光标之间的距离而增加，但其最大射速依然很低。
• 诅咒焰的射弹每次反弹都会提高射速。
• 发射射弹的魔法武器其射速无法改变。
• 近战速度奖励会增加回旋镖等发射射弹的近战武器的射速。
• 射速修饰语在火焰喷射器上会增加其射程。
• 大多数射弹在进入等也液体时会显著降低射速，一些射弹，尤其是和火焰有关的射弹，在进入水体后会立即被摧毁。很多射弹只能维持一定时间，这意味着液体会降低武器的有效射程，而受重力影响的射弹则会产生更加弯曲的曲线。
