Overview: One Arrow, a Whole Web of Lightning
Lightning Arrow is a bow attack gem: you fire an arrow that deals lightning damage, and on hit it arcs lightning chains from the impact point to nearby enemies, turning one shot into a small AoE lightning burst. It is neither a pure single-target arrow nor a pure projectile AoE — it is a hybrid of 'projectile hit + area chain'.
Its most misunderstood aspect is visual: the arrow itself appears to hit only one enemy, but a large share of the damage comes from the chains that arc out after the hit. If you only watch the arrow landing, it looks like overkill in dense packs yet 'does nothing' on a single boss — when in fact its value sits between the two: reliable output on the chosen target plus free splash onto旁边的 trash.
This is exactly why it is often slotted as a secondary burst inside Frost builds (Ice Shot Deadeye, etc.): Ice Shot handles chilling and clearing, while Lightning Arrow steps in when you need dependable single-target and chain补 damage. They share the bow and attack-speed system, so swapping costs almost nothing.
- Essence: bow projectile + post-hit area lightning chain, hybrid single/AoE.
- Damage sources: the arrow's own lightning damage + chains arcing from the hit.
- Visual trap: arrow hits one, but the chains are the AoE body.
- Common partner: Ice Shot Deadeye, as a single-target / chain补 secondary.
Key Stats and Acquisition
- Category
- Active Attack (Bow · Projectile · Lightning)
- Tagged attack, projectile, bow, lightning, aoe, chain.
- Weapon requirement
- Bow
- Requires a bow equipped; in a swap build it lives on the bow set.
- Acquisition
- Uncut Skill Gem
- Unlocked via an Uncut Skill Gem from campaign or drops.
- Projectiles
- Base 1, expandable via supports
- Greater Multiple Projectiles adds arrows; each arrow triggers its own chains.
- Chain targets
- Arcs to several nearby enemies on hit (client-side)
- Chain target count and range scale with gem level and some supports.
- Quality
- Improves chain damage / target count
- Higher quality usually boosts the chained lightning damage or the chain cap.
Mechanics: How the Chain Picks Targets
Chain trigger: when the arrow hits a primary target, it searches nearby enemies around the impact point and arcs lightning chains to them. The chain itself also deals damage, so one hit actually produces 'primary arrow lightning + surrounding chain lightning' as two outputs.
Target selection and range: the chain only looks for targets within a radius of the impact point, and usually deals chain damage to each chained enemy only once (no infinite ping-pong). This means the denser and tighter the pack, the more targets the chain reaches and the higher the overall payoff; spread-out singles or ranged enemies don't fill it.
The 'first hop' comes from the arrow hitting, so projectile hit rate directly decides whether the chain happens. If you use Greater Multiple Projectiles to fire several arrows, each arrow independently triggers its own chains on hit — that is the core trick that turns Lightning Arrow into a clear machine via multi-projectile, but it also means each arrow's single-target damage is split.
- Chain arcs from the hit point to nearby enemies, dealing extra lightning.
- Chain payoff scales with enemies near the impact; dense packs best.
- Multi-projectile makes each arrow trigger its own chain — clear up, ST down.
- Projectile hit rate is the prerequisite for the chain to occur.
Comparison: Lightning Arrow vs Similar Bow Skills
| Skill | Damage form | AoE method | Typical role |
|---|---|---|---|
| Lightning Arrow | Arrow lightning + post-hit chains | Auto-arcing chains around impact | Hybrid ST + chain补, Deadeye secondary |
| Ice Shot | Cold projectile + shatter burst on hit | Cold AoE on impact | Main clear / chill source, often primary |
| Lightning Rod | Summons a lightning pillar at a location | Stationary repeated strikes | Stationary sustained DPS, needs target to linger |
| Lightning Warp | Blink leaving lightning behind | Movement + impact lightning | Mobility / niche blink, not main DPS |
Recommended Support Gems
- Lightning Infusion / Added Lightning
- Core
- Directly amplifies both arrow and chain lightning damage; core for Lightning Arrow.
- Nearly mandatory in lightning-heavy builds.
- Lightning Penetration
- Core
- Ignores part of lightning resistance; strong vs high-lightning-resist mobs and bosses.
- Best paired with Added Lightning.
- Chain
- Core
- Note: Chain makes the projectile itself keep bouncing to other targets — a separate system from the skill's built-in post-hit lightning chain.
- Chain lets the arrow jump again after the primary, widening coverage further.
- Greater Multiple Projectiles
- Situational
- Each arrow triggers its own chain, massively boosting clear.
- Cost: each arrow's damage is split, so single-target boss gets softer.
- Elemental Damage with Attacks
- Situational
- Boosts all elemental damage from attacks; fits elemental bow builds.
- Generic across cold/lightning hybrid setups.
- Martial Tempo / Attack Speed
- Optional
- Raises attack speed, speeding casts and chain frequency.
- Helps builds that need faster ailment stacking or higher DPS.
- Fork
- Optional
- Makes projectiles split on hit, adding messy coverage with chains.
- Usually pick Chain or Fork, not both, to avoid logic conflicts.
Role in Builds
Secondary burst in Ice Shot Deadeye: the primary Ice Shot handles chilling and clearing; when you hit something that can't be frozen or need reliable single-target, switch to Lightning Arrow — it outputs steadily without relying on ailments, acting as 'insurance when ailments fail'.
Pure Lightning Arrow clear build: use Greater Multiple Projectiles + Chain to turn Lightning Arrow itself into a clear machine, feeding chains off dense packs. Cost: weak single-target, needing a separate real boss skill.
Synergy with Herald of Ice / Thunder: elemental bow builds often run a Herald for extra elemental burst; Lightning Arrow's lightning pairs with Herald of Thunder's bolts for stacked clearing, but that adds Mana and Spirit load that must be balanced.
- Ice Shot Deadeye: Lightning Arrow as ST insurance when ailments fail.
- Clear build: multi-proj + Chain fills chains, but ST gets soft.
- Pair with Herald for elemental stacking, watch Mana / Spirit budget.
Common Mistakes: Low Damage / No Chains
Feels weak: you only watched the arrow landing and ignored the chains arcing to nearby enemies after the hit. Direct answer: test in dense packs — the chain payoff far exceeds the single arrow; on a lone boss it simply isn't its strongest form.
Chains don't appear: usually there is no second enemy near the impact (chains need nearby targets to arc), or the projectile missed entirely. Direct answer: confirm the arrow hit and that other enemies are near the target; solo targets naturally starve the chain.
Softer after multi-proj: Greater Multiple Projectiles splits damage across arrows, weakening each arrow's single-target. Direct answer: drop multi-proj for single-target bosses, reinstall for clearing.
Confusing Chain support with built-in chain: Chain support makes the projectile keep bouncing, while the built-in effect is the post-hit lightning chain — stacking both makes people think it 'double triggers'. Direct answer: understand they are independent and choose deliberately, not blindly stack.
- Issue: low damage / no sense of AoE.
- Direct answer: chains are the AoE body — verify in dense packs.
- Issue: chains don't appear.
- Direct answer: need a second enemy near the hit, and the arrow must connect.
- Issue: softer after multi-proj.
- Direct answer: drop multi-proj for ST, reinstall for clear.

Scorpius Lightning Arrow Deadeye author

A Deadeye build built around Lightning Arrow, covering chain support setup, clear and boss single-target cadence.
What to watch for: Watch how the author fills chains with multi-proj + Chain and how they adjust for single-target.
Open source ↗Frequently Asked Questions
How many times does the chain bounce?
On hit it arcs a one-time chain to several nearby enemies; exact target count and range are per current client.
Chain payoff depends on enemies near the impact; dense packs benefit most.
What is the relation between Chain support and the built-in chain?
Chain support makes the projectile itself keep bouncing after the primary target — a separate system from the built-in post-hit lightning chain.
They trigger independently; stacking too many muddies coverage logic, so choose deliberately.
Why does it get soft on bosses after multi-proj?
Greater Multiple Projectiles splits total damage across arrows, weakening each arrow's single-target.
Drop multi-proj or switch to single-arrow for bosses, reinstall for clearing.
