POE2 Currency offers a wealth of options for creative, high-damage builds, and the Witchhunter class shines when it comes to tactical, skill-heavy play. One of the most exciting and destructive options for this class is the Infinite Burn Oil Grenade build. This build focuses on rapid, high-damage oil grenades that inflict burn over time, combined with movement skills and critical strike mechanics to maximize efficiency and survivability. Whether you are farming maps or facing endgame bosses, this build can melt enemies while keeping you mobile and relatively safe.

Core Mechanics of the Build

The heart of this build lies in the synergy between Oil Grenade skills and ignite mechanics. Oil Grenade spreads burning oil in an area, applying fire damage over time. By stacking increased ignite chance, fire damage, and area-of-effect multipliers, you can create near-constant burn damage that quickly clears mobs. The "infinite" aspect comes from cooldown reductions, flask interactions, and skill tree nodes that refresh grenades, allowing you to spam them continuously without downtime.

Critical strike chance and critical strike multipliers play a huge role. The Witchhunter can focus on passive tree nodes and gear that boost critical chance with elemental skills, ensuring each oil grenade hits hard. Items that convert physical or elemental damage to fire further amplify burn effectiveness, turning every throw into a high-value attack.

Skill Gems and Links

For the Oil Grenade setup, key skill gems include:

Oil Grenade-Your main damage dealer.

Elemental Focus-Increases total elemental damage but prevents secondary effects like shocks.

Combustion-Boosts ignite damage and synergizes with elemental multipliers.

Controlled Destruction-Enhances critical strike damage without affecting accuracy.

Support gems like Greater Multiple Projectiles (GMP) can increase coverage for clearing packs, while Fire Penetration ensures bosses and resistant enemies take more burn damage. Movement and utility gems such as Dash or Smoke Mine keep you agile, allowing safe positioning while maintaining pressure.

Passive Skill Tree and Ascendancy

The Witchhunter ascendancy offers several nodes that perfectly complement the Infinite Burn Oil Grenade build:

Grenadier-Enhances grenade damage and reduces mana costs.

Pyroclast-Increases fire damage over time and ignite effectiveness.

Ambush Mastery-Adds critical strike and mobility bonuses for tactical positioning.

On the passive tree, focus on fire damage, area-of-effect, ignite chance, and critical strike multipliers. Life and evasion nodes help survivability, while flask effect enhancements improve sustain during intense fights.

Gear Recommendations

This build benefits from gear that enhances fire damage, ignite chance, and critical strike. Weapons that increase elemental damage or ignite duration amplify grenade damage significantly. Armor with life, resistances, and evasion improves durability.

Flasks play a pivotal role. Mana and life flasks with instant recovery keep you in the fight, while utility flasks that increase movement speed or immunity to ignite shocks improve mobility and safety.

Playstyle and Strategy

The Infinite Burn Oil Grenade Witchhunter excels at hit-and-run tactics. Use grenades to apply burn to groups of enemies, then reposition with movement skills. Boss fights require careful spacing-spread grenades to maximize DoT uptime while avoiding unnecessary damage.

Combining flask usage, mobility, and critical strike timing lets you maintain near-constant damage while staying agile. The build rewards patience, positioning, and skillful grenade placement, making each encounter feel dynamic and tactical.

This build scales well into maps and endgame content. With proper investment in ignite multipliers, critical strike chance, and area-of-effect, bosses and dense packs fall quickly. The "infinite" burn mechanic ensures minimal downtime, allowing fast clears and sustained pressure without relying on melee or heavy cooldowns.

In summary, the Infinite Burn Oil Grenade Witchhunter build in cheap POE2 Currency is perfect for players who enjoy high mobility, strategic positioning, and overwhelming burn damage. By leveraging ignite mechanics, critical strikes, and grenade synergy, you can dominate maps, tackle bosses, and maintain near-constant damage output with style.
