Best Skill Gem Setup for Gas Grenade Pathfinder (0.3.0)
The build's primary skill, Gas Grenade, needs a full five-link to
Path of Exile 2 Currency shine. Here's the recommended endgame setup:
Gas Grenade: Arakali's Lust - Deadly Poison II - Elemental Armament II - Persistent Ground III - Encroaching Ground (swap to Elemental Focus on bosses).
Ghost Dance: Compressed Duration II.
Wind Dancer: Blind II - Maim - Magnified Area II.
Despair: Heightened Curse - Prolonged Duration II - Efficiency II.
Withering Presence: Prolonged Duration II - Clarity I.
Toxic Domain: Escalating Poison - Deadly Poison II - Long Fuse II.
Leveling tip: Use Gas Grenade (Bursting Plague, Corrosion) alongside Contagion (Unleash) for smooth progression. For bosses, keep Explosive Grenade ready to trigger big bursts while layering poison clouds.
BiS Itemization for Gas Grenade Pathfinder
This build isn't overloaded with mandatory uniques, but a few Path of Exile 2 Items significantly boost its power:
Plaguefinger (mandatory) - Converts all damage from hits to poison magnitude, dramatically improving scaling. A corrupted version with +1 socket is ideal.
Main Weapon: Siege Crossbow - Your primary damage source.
Secondary Set: Cursecarver (wand) + Arvil's Wheel (shield) - Optimized for Despair casting. Aim for Cursecarver with +4 to Despair and Arvil's Wheel with a high skill effect duration.
Jewel Options:
Prism of Belief with +Gas Grenade levels.
From Nothing, ideally slotted near Chaos Inoculation, for synergy with Pure Chaos and Wither Away.
If you're struggling to gear up, many players turn to buy POE2 Items and buy POE2 Currency to progress. Since poison scaling depends heavily on multipliers and +skill levels, getting well-rolled rares and uniques early makes a huge difference.
Passive Tree, Ascendancy, and Keystone Highlights
Gas Grenade Pathfinder primarily traverses the right side of the passive tree, focusing on chaos damage, poison scaling, and survivability. Key nodes include:
Overwhelming Toxicity - Doubles the number of poisons that can be applied simultaneously.
Contagious Contamination - Spreads poison to nearby enemies on kill.
Escalating Toxins - Increases poison duration based on recently inflicted stacks.
Chaos Inoculation - Grants immunity to chaos damage and bleeding, but reduces max life to 1. This pairs well with evasion and ES layers.
Wither Away - Boosts withered effect magnitude by 20% and applies Wither to nearby enemies.
Pure Chaos (via From Nothing jewel) - Converts 100% of damage into extra chaos damage.
These nodes ensure poison not only applies quickly but scales into
buy POE2 Currency devastating levels of single-target and AoE damage.
