投射物

投射物 are entities which are produced by a 法術 or ranged 攻擊 which travel independently of their creator until they collide with an enemy or obstacle or reach their travel distance limit of 150 Units. Skills gems that create projectiles usually have the Projectile or 弓箭 gem tag.

速度和持續時間

All projectiles have a speed, which can be altered by Projectile Speed modifiers. All projectiles also have a duration (which can be infinite), although in most cases this duration is not mentioned anywhere and cannot be modified, unless explicitly stated such as with the skill 電球.

The speed and duration combined determine the distance the projectile will travel, up to its maximum range. This is important when considering projectiles that have a limited lifetime.

For example, 冰霜脈衝 creates projectiles which deal full damage initially, but deal less and less damage the longer they are alive. Increasing the Projectile Speed of Freezing Pulse will cause the projectiles to arrive at the target sooner, and therefore they will deal more damage than a slower-moving Freezing Pulse that traveled the same distance.

Increasing the Projectile Speed of limited duration projectiles will allow them to travel a further distance before they expire.

However, there are effects that occur based on the projectile's total distance traveled since launched. For instance:

• 冰矛 will always arm (change into its second form) at a certain distance from its launching point, regardless of its speed The damage modifiers from 零點射擊 and 亂矢之弦 are based the projectile's total distance traveled, not how long the projectile has been alive. Note that, in the case of 靈體投擲 or other "Projectiles Return" mechanics, the total distance traveled may be greater than the current distance from the player.

Ground and airborne projectiles

Most projectiles fly through the air, however there are some that travel along the ground.

Airborne projectiles can be aimed up and down cliffs and other height transitions, and can impact with the ground or ceiling. This can sometimes make them difficult to aim when dealing with a steep vertical angle, as they might fly over the heads of enemies or harmlessly impact the ground at the enemy's feet. Airborne projectiles will pass through most low obstacles such as small chests and rocks.

Projectiles that travel along the ground are subject to the same restrictions as a walking player. This means they cannot be fired up or down height transitions, and will instead collide with the edge. They will never impact with the ground or ceiling, but they are much more likely to be obstructed by small obstacles around the environment. Skills that create earthbound projectiles include 電球, 閃電打擊.

Death

When a projectile collides with an enemy or obstacle, it explodes and is destroyed. This happens even if the projectile is the result of an attack that is evaded or dodged. Intuitively a projectile that is evaded or dodged would continue along its trajectory, but that is not the case in Path of Exile.

Subprojectiles

Normally a projectile attempts to hit the first enemy it encounters, explodes if the projectile has an explosion effect, and disappears. However, some effects change the projectile hit behavior.

效果類別

At most one effect may be applied per hit. The effects are listed in order of priority.

裂化

"Split" redirects here. For the item modifier, see Split (item modifier).

Upon 擊中 the projectile splits into (X) number of auto-targeting projectiles. The auto-targeting radius limitations are similar to chain.

Split arrows are considered the same arrow after splitting and therefore will not target the same monster twice. This means that in most situations split will not increase your single target hits. (see explosive projectiles for exception)

Sources of split include:

• 狙擊者印記

• 憤怒閉鎖

穿透

Main page: 投射物穿透

The projectile passes through the enemy and continues along its previous trajectory. Once a projectile has exhausted its pierce count, one of the other effects listed in this section may apply.

分裂

The projectile splits into two identical projectiles which each travel at a 60 degree angle from the projectile's original path. A projectile can only fork once.

Sources of fork include:

• 分裂輔助

• 瑞佛之羽

• 蛇巢 (For spell projectiles when worn in the left ring slot)

連鎖

The projectile chooses a target within a certain radius, and travels in the direction of that target. A target cannot be hit twice by the same projectile. If a skill produces multiple projectiles at once and chains, none of the projectiles may chain to an enemy which has already been struck by a projectile from the same attack or cast. If there are no valid targets in range of the original enemy, it will target an enemy but not hit, instead passing through. Chain has a specified number of iterations.

Sources of chain include:

• 連鎖輔助 and 覺醒．連鎖輔助

• 伊沃幻像 (For attack projectiles when in main hand)

• 憂愁獠根

• 沉默之雷Ricochet passive for the 銳眼 ascendancy.

• 蘿絲之觸

• 蛇巢 (For spell projectiles when worn in the right ring slot)

• 極度苦痛 (While at maximum frenzy charges)

• 贗品．虛空行者 (For projectiles while you have phasing, which is also granted if you have killed recently)

Also, 電弧, 瓦爾．電弧, 充能打擊, 野性打擊, 暗夜血契, 風暴漩渦, and 暴風之盾 can chain despite not being projectile skills.

返回

The projectile returns to the original firer. Targets can be hit once on the way out and once on the way back, however, the specific target they return from is only hit once. Its priority is after pierce/fork/chain.

Sources of returning projectiles include:

• 靈體投擲

• [[Vengeant Cascade passive]] (for attack projectiles)

• 輪迴之記 (Descent: Champions-exclusive)

Explosions

Some projectiles explode on every hit, while other projectiles only explode when they disappear, dealing only normal, non-area damage on non-exploding hits.

The following skills explode on every hit:

• 腐蝕箭矢

• 冰霜射擊

• 力量爆破

• 閃電箭矢

• 瓦爾．燃燒箭矢

Furthermore, all single-target on-hit effects apply on every hit.

The following skills only explode when the projectile is destroyed:

• 寒霜滲透

• 爆炸箭矢

• 火球

• 靈魂吸取

Math Calculations

All calculations assume maximum possible hits in ideal situations. Several factors, for example enemies evading your attacks, will prevent max possible hits from happening.

Solo hits

Individual projectiles can only target a single monster 1 time. If you have multiple chains, they will only chain to targets that have not been hit yet.

Projectiles that fork count as the same projectile after forking. This means that fork will not increase your solo target hits per second, unless the projectiles do explosive damage to non-targeted enemies.
