Are you tired of dealing with complex mechanics, overly convoluted builds, or having to remember an endless array of buttons and combos just to do some decent damage? Do you long for the simple POE 2 Currency Orbs, brain-dead experience where you can effortlessly blast through tier 17 maps and destroy bosses with ease? Look no further, because this guide is here to show you the power and beauty of the Gas Arrow One-Button Build, the ultimate bow-based powerhouse in Path of Exile 2 (POE 2).

This build is not only ridiculously fun and insanely powerful, but it's also incredibly simple to play. If you've ever wanted to feel like an unstoppable force of nature in POE 2 without dealing with a billion different mechanics, then you've come to the right place. Let's dive into everything you need to know to master this high-powered, single-button build and make POE 2 fun again.

Why Gas Arrow is So Strong

The Gas Arrow build gained its strength due to a combination of mechanics that make it one of the most potent builds in POE 2. Originally, Gas Arrow was a decent skill, but due to the right set of buffs and a lack of nerfs in the last major patch (0.1), it was able to dodge the Nerf Hammer and explode in power. In fact, it's become one of the most viable bow builds in the entire game by nuking almost everything in its path.

The core of the Gas Arrow build is simple: it's all about explosions. At its core, Gas Arrow fires a projectile that generates a toxic green cloud of gas (you could call it a “booger cloud”), which doesn't deal much damage itself. However, the real magic happens when this cloud explodes for substantial fire damage – and this explosion is what we're after.

Igniting Enemies: The Key to Explosive Damage

The explosion from the Gas Arrow cloud doesn't deal much damage by itself. What makes the build truly deadly is igniting the enemies so that the cloud's explosion deals devastating fire damage. There are several ways to ignite enemies in POE 2, and we'll focus on the most accessible and efficient methods:

    Cast a Skill that Ignites Enemies (Flame Wall): While leveling, this is your best option. Flame Wall is a simple, low-cost skill that will help you set enemies ablaze.

    Radiant Grief Lace Hood: This unique item allows you to automatically ignite enemies when you approach them, making it ideal for the Gas Arrow build.

    Scaling Fire Damage & Ignite Chance: For the ultra-endgame version of this build, you can focus on maximizing fire damage and ignite chance. However, this is a more advanced setup and requires significant gear investment.

For most players, the first two options will be more than sufficient for clearing content up to the endgame, and they provide the ignition we need to trigger explosive damage.

A One-Button Build: The Simplicity of Gas Arrow

One of the key selling points of this build is its simplicity. You may be wondering, if this is a one-button build, what are the other skills in the action bar doing? Let's break it down:

    Gas Arrow: This is your primary skill and the one you will use most of the time. You simply hold down the button, and the explosions take care of everything.

    Flammability: This skill is used only for bosses, reducing their fire resistance to make them more susceptible to your fire damage. This ensures your ignites hit harder during boss fights.

    Orb of Storms: This skill is used for boss encounters as well. It grants you rage (boosting attack damage) and mana generation (to avoid running dry of resources during the fight). You cast it just before the boss fight starts.

    Freezing Salvo: This is an optional skill that you can use to increase your damage output while mapping, especially for rares and large packs. It grants 35% additional damage during mapping, but it's not necessary for the endgame version of the build.

In summary, while you'll have a few other skills, your primary focus for clearing maps is simply Gas Arrow. For bosses, you'll use Flammability and Orb of Storms to prepare, then spam the Gas Arrow button.

Support Gems: Boosting Gas Arrow Damage

Now, let's talk about the support gems you'll use to make your Gas Arrow explosions even more deadly. You'll want to focus on conditional multiplier gems, which boost the explosion damage without affecting the projectile damage too much. Here's a list of the support gems you should aim for:

    Rising Tempest: This boosts your damage when using different elements, which is important because this build scales both fire and lightning damage.

    Marshall Tempo: This makes your clearing speed faster, allowing you to clear through maps more efficiently.

    Close Combat: This is useful for getting up close and personal with enemies, ensuring you trigger your ignite effects while dealing more damage.

    Immolate: This gem enhances your fire damage, and if you're not using Radiant Grief to ignite automatically, this gem becomes critical. However, if you're aiming for an ultra-endgame version, you'll want to drop this gem.

    Magnified Effect / Concentrated Effect: These gems are interchangeable depending on the scenario. For mapping, use Magnified Effect to clear faster. For bossing, use Concentrated Effect to increase your damage output.

The Gear: Essential Items for the Gas Arrow Build

Now that we've covered the skills, let's move on to the most important part of the build: the gear. Here's what you'll need to look for at different stages of your progression:

    Radiant Grief: This is your most important item, as it allows you to ignite enemies instantly. It's relatively inexpensive, so grab it early on.

    Bow: Your choice of bow will significantly affect your damage output. Here are some options:

        Widow Hail: Great for adding additional projectiles, which improves your clear speed.

        Death's Harp: The best choice for clearing maps, as it also adds extra projectiles.

        Dual String Bow: If you're on a budget, a solid, regular bow with good stats will work as well.

    Gloves: Focus on flat damage, max life, and evasion. As you progress, consider getting Northpore gloves for extra crit, or Hand of Wisdom and Action for more lightning damage.

    Belt: Look for a belt with max life and resistances. As you progress, switch to Ingenuity Belt for better quiver bonuses, but make sure your other gear is solid first.

    Rings: Aim for rings with flat lightning/fire damage, max life, item rarity, and resistances. These will help you stay alive while dealing more damage.

    Chest: Evasion is crucial for survivability, so look for a chest with a high evasion value. Pair this with the Beastial Skin passive to double your evasion and stack energy shield.

    Boots: Go for movement speed and additional evasion, making sure you can dodge hits and move quickly through maps.

    Amulet: Focus on defensives, such as resistances and max life. Consider anointing it with one of the many useful options available depending on your budget.

Passive Tree and Ascendancy

For the passive tree, focus on increasing your damage, evasion, and mana on kill. This will make your mapping experience smooth and allow you to sustain your mana without worrying about running out.

As for your ascendancy, you'll want to take the following nodes:

    Point Blank: For massive damage boost.

    Endless Munitions: Doubles your projectile count, making your clear speed even faster.

    Tailwind: Increases movement speed and provides a 30% damage reduction, making you nearly invincible.

From there, stack as much damage, crit, and evasion as possible. If you have energy shield, grab the Spectral Ward passive to double your energy shield and evasion.

Mapping and Bossing Tips

When it comes to gameplay, mapping is a breeze with Gas Arrow. Simply hold down the Gas Arrow button and watch as the explosions clear the entire map. You can use Freezing Salvo every 5 seconds for an additional damage bonus if you're feeling fancy.

For bosses, it's a bit more involved, but still easy. Before engaging the boss, use Orb of Storms to gain rage and mana, then drop Flammability to reduce their fire resistance. After that, spam the Gas Arrow button to bring the pain.
