Explosive Arrow

Explosive Arrow is a bow attack skill that fires an arrow which sticks to an enemy or wall and detonates after a duration, dealing fire area of effect damage. Any additional arrows stuck to the enemy after the first one will add its damage to the explosion. Additional arrows on an enemy increases the hit damage, ignite damage, and area of effect of the explosion.

Skill functions and interactions

Explosive Arrow has two separate damaging effects: an attack and an explosion.

Attack: The Explosive Arrow attack is an arrow which deals weapon damage based on the bow equipped. This component of the skill is affected by any modifiers to bow attacks. At the final destination of the arrow, one of three effects will occur:

• If the arrow gets stuck on the terrain or on an obstacle, it will leave a single fuse charge that will explode after a duration.
• If the arrow gets stuck on a target that does not yet have the debuff Hit by Explosive Arrow, it will apply that debuff with a single fuse charge, which creates an explosion when it expires after a duration.
• If the arrow gets stuck on a target that already has the debuff Hit by Explosive Arrow, the arrow's intended explosion damage will get added to the final explosion. However, the debuff duration will NOT be refreshed.

If the arrow pierces or is evaded by a target, it will not leave a fuse charge on the target, but can still leave a fuse charge on the terrain behind it.

Chaining this projectile will only leave a Fuse Charge on the last target struck, and due to the speed of the initial projectile, can sometimes miss the intended target and collide with an object or terrain, placing a Fuse Charge on the location it hit.

Explosion: When the debuff Hit by Explosive Arrow, or a fuse stuck on terrain expires, it causes an explosion based on the number of fuse charges. This damage is area projectile fire damage, which is also considered bow damage and will scale with sources of weapon damage, bow damage, etc.

If the arrow that applied the Hit by Explosive Arrow debuff is a crit, the explosion will also crit. While subsequent arrows which have crit will apply its total damage to the explosion after critical strike modifiers, the explosion itself will not crit.

Duration: Modifiers to duration, such as from , will affect the duration of the debuff when it is applied, as well as the duration of the fuse charge if it hits the terrain or an obstacle.

Totem: Ballista Totems will execute this attack until the targeted enemy dies, instantly triggering the explosion, or until the totem is destroyed, causing the applied Fuse Charges to last their remaining duration before exploding.

Alternate skill effects

Explosive Arrow has the following alternate skill effects:

Version history

Version	Changes
3.15.0	Explosion now deals 5% more Damage with Hits and Ailments per Explosive Arrow on Target (previously 3%).
3.10.0	Now gains +2 to Explosion Radius per Explosive Arrow on the target, up to +12 at all gem levels (previously scaled as the gem levelled up, from +10 at gem level 1, to +19 at 20). You can now stick a maximum of 20 Explosive Arrows to an enemy (previously no limit). Explosions now deal 3% more damage with Hits and Ailments per explosive arrow on the target (previously, this only applied to ignites).
3.9.0	Now costs 8 mana at gem level 1 (from 18), up to 10 at gem level 20 (from 27). Arrows stick into the enemy or wall and explode after a duration. The duration no longer refreshes whenever a new arrow is attached (previously they were handled like "charges", which refresh their duration whenever a new one is gained). If an enemy has multiple arrows stuck in them, the first one to explode will consume all other attached arrows, adding their damage to the first arrow's explosion. On-hit effects such as Chance to Ignite or Critical Strikes are determined by the exploding arrow, however each arrow's damage is calculated with their independent critical strike chance taken into account. For example, if the exploding arrow did not successfully roll a critical strike or ignite, the explosion will not ignite. If two other arrows were also attached at the point of the explosion and they successfully rolled to critically strike, they will add their critical strike damage to the explosion, but it will not cause an ignite (or trigger any other on-critical-strike effects). Explosions now deal 50% of base damage (previously weapon damage was not taken into account). Explosions now also deal added fire damage based on gem level, up to 522 to 783 at gem level 20 (from 586 to 879). Now inherits its base critical strike chance from your weapon (previously had a 6% base critical strike chance). Now gains +2 to explosion radius up to a cap determined by gem level, up to +19 at gem level 20. Previously it naturally capped at +10 due to the charge limit. Explosions now deal 3% more damage with Ignite per explosive arrow on the target.
