Poisonburst Arrow Pathfinder

Poisonburst Arrow Pathfinder — Full Guide (0.5.4)

Build Overview

This is a high-efficiency poison bow build centered on Poisonburst Arrow and the Pathfinder ascendancy. The core loop:

1. Poisonburst Arrow fires arrows that apply multiple poisons in a wide area on contact;
2. Herald of Plague automatically spreads your strongest poison to nearby enemies;
3. Spreading a poison triggers Bursting Plague — monsters explode for a percentage of their maximum life, chaining explosions through the pack for one-button screen clears.
4. Pathfinder's Overwhelming Toxicity doubles the maximum poison stacks per enemy, while Running Assault grants Heavy Stun immunity while Sprinting and superb repositioning — letting you weave between attacks without slowing your clear.

Early leveling requires a multi-button kit (Lightning Arrow / Frost Bomb / Gas Arrow) since monsters are tanky, but once your ascendancy is complete, the build evolves into one-button clearing + multi-button bossing.

Skill Breakdown

Leveling

Level with lightning/cold, then convert to poison at level 22 (after completing the Trial of the Sekhemas for Overwhelming Toxicity).

Transition timing: at level 22, after your first ascendancy grants Overwhelming Toxicity, respec fully into poison nodes and switch to a physical bow (note: elemental damage doesn't scale poison at this point — not until Plaguefinger).

Mapping

Mapping is essentially one button: Poisonburst Arrow → the pack detonates.

Bossing (single target)

Key support: Garukhan's Resolve — double crit chance / a chance for crit damage to double again. Recommended in Toxic Growth (or your main skill). Alternative: Blindside.

Auras / Buffs

Skill Rotations

Mapping (one-button):

Poisonburst Arrow → poison spreads → Bursting Plague chains → reposition, keep firing
Elites / tanky leftovers: add Toxic Growth

Bossing (multi-button):

1. Pre-cast at the boss spawn: Vine Arrow + Despair
2. Boss appears → maintain Vine Arrow / Despair debuffs
3. Toxic Growth spawns pustules → detonate with Poisonburst Arrow / Gas Arrow
4. Loop the Toxic Growth detonations until the boss dies
5. Refresh Vine Arrow + Despair as needed

Ascendancy (Pathfinder)

Take the nodes in order:

1. Overwhelming Toxicity — doubles maximum poison stacks per enemy (cost: -35% poison duration, offset by frequent Toxic Growth detonations). The foundation of the entire build.
2. Path Seeker (with its adjacent small nodes) — 5 passive points total, essentially a free expansion.
3. Relentless Pursuit — immunity to all Slows (Chilled Ground / Temporal Chains, etc.), a huge mapping mobility upgrade.
4. Running Assault — 50% less Movement Speed penalty while using skills; Heavy Stun immunity while Sprinting, rewarding active dodging.

Passive Tree

Pathing Priorities / Key Notables

The original doesn't list specific notable names (full node IDs require the planner), but it clearly emphasizes these groups:

• Critical Strike Chance — a high-crit bow makes the tree's crit nodes pay off massively
• Poison Damage (increased poison damage + duration + ailment magnitude)
• Evasion / Life double-track expansion (main defensive layer)
• Subterfuge Mask — the key gate: only after allocating it can you wear a pure ES helmet
• Attribute nodes — just enough Int / Dex for gear + gems, everything else into Strength for max Life

Progression milestones

• Early: Life + Elemental Damage
• After the Lv22 ascendancy: respec fully into Poison + Evasion nodes
• Midgame: transition from pure Evasion to Evasion / ES double-track
• Late: unlock Subterfuge Mask, bringing the pure ES helmet online

Stat Priorities

Offense (high to low)

Iron rule: poison inherits the damage composition of the hit that applied it — a poison from a physical hit does NOT benefit from chaos damage modifiers applied post-hit.

1. Your bow is everything: high physical + (after Plaguefinger) high elemental
2. +# Level of all Projectile Gems
3. % increased Damage (any type)
4. +# Intelligence / Dexterity (to meet gear/gem requirements)
5. # to Fire / Cold / Lightning / Physical Damage to Attacks
6. % Global Physical Damage
7. % Increased Attack Speed
8. Gain % as extra Phys/Chaos/Fire/Cold/Lightning
9. Bow Attacks fire an Additional Arrow
10. % increased Chance to Shock
11. % increased Mana gained per Enemy Killed

Rough jewel affix priority:

• % Inc Damage with Bows
• % Inc Global Physical Damage
• % Inc Evasion Rating
• Recover # % of Mana on Kill
• % Inc Projectile Damage
• % Inc Attack Damage
• % Inc Magnitude of Ailments
• % Inc Magnitude of Poison
• % Inc bonuses from Equipped Quiver

• % Inc Movement Speed

• % Inc Poison Duration
• % Inc Attack Speed with Bows
• % Inc Attack Speed
• +# % to Energy Shield

Defense (high to low)

1. All four resistances (elemental + chaos) capped at 75% (mandatory)
2. + Maximum Life
3. Evasion Rating (your main avoidance source)
4. Energy Shield (recovered on hit via Ghost Dance)
5. Wind Ward (instant on-hit, massively raising your max single-hit survivability)
6. Movement Speed (active dodging)
7. Blind (reduces enemy accuracy)

Gearing Strategy

Campaign

All-purpose vendor regex:

"ts: S|\d+% i.+mov|d Ph|ds .+Da|ll P|k Sp"

Searches: Sockets / Move Speed / Inc Phys / Flat Phys / Flat Ele / Projectile Skills Level / Attack Speed.

Early Mapping

Endgame

The original provides 4 complete gear templates: Campaign / Maps / Voltaxic Hybrid / Physical Hybrid.

Mana Sustain

Neither Poisonburst Arrow nor Gas Arrow is cheap per shot — without a plan, your clear stalls. Run all three at once:

1. Your best Mana Flask
2. A Sapphire Basic Jewel with at least 1 line of Recover 2% of Mana on Kill
3. Gain # Mana per Enemy Killed on your Bow / Quiver

Quoting the original: "a Sapphire Jewel with % of Mana on Kill and a source of Gain # Mana per Enemy Killed from either your bow or quiver smooth out any mana issues you have".

Playstyle Tips

• The bow sets your ceiling — "Your Bow is everything: High Physical Damage and Elemental Damage roll on top makes or breaks your build".
• Poison inherits the hit's damage composition — poison from a physical hit doesn't benefit from chaos damage modifiers (a common misconception).
• Scattershot is excellent early in the poison transition — multiple projectiles per shot = multiple poison stacks per shot.
• Check and upgrade gem quality daily — the damage gain is significant.
• Withering Presence auto-stacks Wither — boosting chaos damage taken by enemies and dramatically speeding up boss fights.
• Subterfuge Mask is the key gate — don't switch to a pure ES helmet before allocating it.
• Before Plaguefinger, don't chase elemental stats on gear — pure physical / chaos affixes only.

Optional Campaign Buffs

The original notes: "These bonuses are minor, if you picked something different, don't worry too much!"

Summary

• Strengths: the natural synergy of Pathfinder's doubled poison stacks + spread + explosions; one-button clearing; Heavy Stun immunity while Sprinting and full Slow immunity for elite mobility; a lean main-key layout.
• Weaknesses: early leveling needs multiple skills and tanky mobs feel rough; gearing "gates" at Plaguefinger and Subterfuge Mask; the bow is the build's core, so drop/craft luck matters.
• Who should play it: anyone who wants a satisfying clearer + durable mapper + boss-capable bow build and doesn't mind restructuring gear/passives around Plaguefinger and Subterfuge Mask in the mid-to-late game.
