Build Overview
Gas Grenade Pathfinder is the Ranger poison-cloud toolkit: Gas Grenade spawns a Poison Cloud at the impact point, and overlapping grenades enlarge the cloud and its stacks. The Pathfinder ascendancy boosts damage-over-time and flask/ground effects, making the cloud the main output.
The key is not 'throw accurately' but 'pre-lay'. In bossing you lay the cloud before the boss arrives, then pile stacks with Despair / Toxic Domain / Wither. Mapping covers packs with continuous throws.
Too-short Poison Duration makes the boss health bar dip then stall — the most common 'weak single-target' root cause. This guide explains duration breakpoints and pre-lay order, with all client numbers flagged for PC verification.
- Gas Grenade spawns overlapping Poison Clouds.
- Pathfinder boosts DoT and flask/ground effects.
- Weak bossing usually comes from Poison Duration, not gear.
Pros and Cons
Pros
- Clouds auto-deal DoT; mapping barely needs aiming.
- Stacking makes the boss health bar slide steadily.
- Pathfinder flask/ground buffs add error margin.
- Low budget already maps and bosses most content.
Cons
- Too-short Poison Duration stalls and single-target looks weak.
- Moving targets (e.g. flying bosses) lower cloud coverage.
- Chaos Res and ES recovery are hard late-game needs.
- Pre-lay rhythm needs practice; random throws waste output.
How the Loop Reads: Pre-lay Clouds
Mapping loop: throw Gas Grenade continuously at packs so clouds overlap; you just position yourself outside the cloud and mobs inside.
Boss loop: pre-lay 1–2 clouds before the boss reaches the spot, then Despair for res reduction, Toxic Domain for stacks, Wither to amplify. Dark Effigy can add a persistent cloud layer.
Cloud spread is an area effect, not a projectile; laying it where the enemy will be matters more than aiming at the enemy.
- Mapping = continuous throws, overlapping clouds.
- Boss = pre-lay → Despair → Toxic Domain → Wither.
- Cloud is ground effect; pre-lay beats aiming.
Leveling Path
Levels 1–14 · 1–14
Map with a basic bow/crossbow skill; Gas Grenade is a filler once unlocked, stacks not yet formed.
Levels 15–29 · 15–29
Take Gas Grenade and start stacking clouds; add life/evasion/Chaos Res nodes.
Levels 30–42 — Pathfinder Unlocks · 30–42
Pick Pathfinder, boost DoT and ground effects; boss pre-lay stabilizes.
Levels 43–60 — Early Maps · 43–60
Run the cloud loop on low budget; add Despair / Toxic Domain links, fix resistances.
Skill Setup
Core Skills
Supports: poison-army · increased-area · acute-poison
Why: It is the core of the whole toolkit; no cloud without it.
When to replace: Never replaced; it is the start.
Mapping vs Bossing: Mapping: continuous coverage. Boss: pre-lay 1–2 then buffs.
Duration and stacks scale via supports and buffs.
Supports: hex-bloom
Why: Required for boss single-target; without res reduction cloud damage caps low.
When to replace: Keep as the curse setup.
Mapping vs Bossing: Mapping optional; boss mandatory.
Why: It maxes cloud stacks; key to single-target damage.
When to replace: Keep; high investment but necessary.
Mapping vs Bossing: Used in both, boss more dependent.
Why: Steady chaos boost, raises output in all scenes.
When to replace: Keep.
Mapping vs Bossing: Used in both.
Supports
Why: Extra poison layers and buff, strengthening overall DoT.
When to replace: Keep as a buff.
Mapping vs Bossing: Used in both.
Why: Adds another cloud layer on boss pre-lay, raising coverage.
When to replace: Place only when more coverage is needed.
Mapping vs Bossing: More useful in bossing.
Ascendancy Order
Pathfinder — First Nodes
Prioritize nodes boosting DoT and ground/flask effects; this is the base of the cloud toolkit.
Defense Check
If dying at T15+, add Evasion / ES / Ghost Dance nodes; do not trade all for damage.
Passive Tree
Campaign
Take DoT, chaos, area and evasion/life; do not pre-path to ES wheels.
Early Maps
Switch into the cloud variant; Poison Duration, Chaos Res and ES first.
Endgame
After defense and duration are solved, invest in damage wheels; compare gear at the same tier.
Gear
Bow / Crossbow (throwing base)
Required
- Skill level / Chaos DoT — Directly scales cloud resolution.
Recommended
- Thrown/area skill damage — Raises overall throw output.
Optional
- Cast/throw speed — Faster cloud lay.
Luxury
- Extra poison stacks / crit — Only after duration is stable.
- Pick a base boosting thrown/area skills and chaos damage; enough sockets for the Gas Grenade links.
Throwing base: prioritize skill level and chaos mods.
Body / Boots / Helmet
Required
- Life and two capped resistances — Cloud builds still die.
Recommended
- Evasion / ES (with Ghost Dance) — Late defense boundary.
Optional
- Movement speed — Better pre-lay positioning.
Luxury
- Explicit chaos damage — After defense.
- Evasion, ES, life and resistances; boot movement speed.
Ghost Dance needs ES; do not stack only evasion.
Rings / Amulet / Belt
Required
- Attributes to equip weapon and gems — Un-equippable is useless.
Recommended
- Chaos Res and ES recovery — Hard late-game needs.
Optional
- Flask effect/duration — Pathfinder amplifies flask gains.
Luxury
- Skill level — Late-game damage.
- Attributes, resistances, life and Chaos Res; ES recovery where needed.
Stat Priority
- Cloud skill level / Chaos DoT — Scales cloud resolution; top progress check.
- Poison Duration — Core to avoiding boss-health stall.
- Chaos Res and ES recovery — Hard late-game survival need.
- Evasion / ES (Ghost Dance) — Defense boundary, needs ES.
- Throw/Cast speed — Faster lay, after defense.
Upgrade Priority
Boss in cloud but damage stalls
Symptom: Boss health dips then stops.
Check first:
- Is Poison Duration enough?
- Does re-throw frequency match?
Upgrade next: Increase duration or adjust throw rhythm, not swap weapon.
Strong clear but weak single-target
Symptom: Fast mapping, can't dent boss.
Check first:
- Missing Despair / Toxic Domain / Wither?
- Is boss loop complete?
Upgrade next: Complete single-target prep (res reduce + stacks + buff).
Dying often
Symptom: Frequent deaths in maps or boss.
Check first:
- ES recovery or Evasion gap?
- High rollover map mods?
Upgrade next: Fix defense first, stop stacking damage.
Low coverage on moving boss
Symptom: Flying/dashing boss misses cloud.
Check first:
- Pre-laid before boss path?
- Dark Effigy adding layer?
Upgrade next: Pre-lay + extra cloud source, not more damage.
Mapping
Throw Gas Grenade continuously at packs so clouds overlap; keep yourself outside the cloud and mobs inside, roll to reposition.
Trash does not need Despair; only rares/bosses get res reduction and stacks. When clear slows, upgrade the throwing base before stacking defense.
- Continuous throws, overlapping clouds.
- Skip Despair on trash.
- Upgrade throwing base first when clear slows.
Bossing
Pre-lay 1–2 clouds before the boss reaches the spot, then Despair for res reduction, Toxic Domain for stacks, Wither to amplify, Dark Effigy for an extra layer.
If the bar stalls, the issue is Poison Duration / re-throw frequency, not gear. Moving bosses need clouds laid ahead of their path, not chased.
- Pre-lay → Despair → Toxic Domain → Wither.
- Dark Effigy adds a cloud layer.
- Stall = fix duration, not swap weapon.
Poison Duration Breakpoints
Poison Duration decides how long a stack persists on the target. Too short makes the boss bar stop sliding after stacks expire, creating a false 'weak single-target' impression.
Raise it via support duration mods, Toxic Domain's buff, duration/area mods on gear, and Pathfinder's ground-effect nodes. Exact numbers pending PC verification; verify in client.
- Too-short duration = boss bar stalls.
- Duration/area mods and Toxic Domain extend together.
- Verify against client.

FAQ
What level does Gas Grenade unlock?
Exact level pending PC verification; once unlocked it is filler, the stack toolkit forms after Pathfinder.
- Start laying clouds after unlock.
I swapped a better bow but single-target is still weak?
Single-target depends on Poison Duration and res-reduction/stacks, not the bow; fix duration and boss pre-lay first.
- Record boss fight, check cloud coverage.
How do I fight moving bosses?
Pre-lay clouds ahead of their path and add a Dark Effigy layer; do not chase-throw.
