In Path of Exile 2: Return of the Ancients, Burning Build continues to rank among the most powerful setups, owing to its multiple overturned mechanics: immense explosion damage; grenade damage scaling with Skill Gem level rather than weapon; flexible movement; and minimal changes in the latest patch.
While Burning Build’s strength is undeniable, it has a significant drawback: the long explosion time makes timing difficult. Therefore, PORCURRENCY.com, a professional gaming website, introduces a perfect build that addresses this weakness while achieving a similar damage mechanic – No Grenade Mercenary Build.
The core feature of this build is abandoning the traditional mercenary’s reliance on throwables. It achieves both melting bosses while standing still and One-click screen clearing through the synergy of ice elemental freezing and high physical ammo output, resulting in overwhelmingly efficient damage.
Below, this site will comprehensively explain this powerful build from five aspects:

Significant Changes and Equipment
Practical Data and Endgame Performance
I. A Choice More Adaptable to Updates
Based on the in-game balance adjustments in Path of Exile 2 patch 0.5.0, the developers have almost completely nerfed the current mainstream builds.
Poison Pathfinder, which dominated patch 0.4.0, has been significantly weakened; the poison duration of Overwhelming Toxicity talent has been reduced from 35% to less than 50%.
The maximum poison duration of Gas Arrow has been reduced from 4.9 seconds to 3 seconds, and the maximum number of poison-generated pustules has plummeted from 12 to 5, resulting in an almost halved overall damage output.
In addition, the energy shield and life steal mechanics have also undergone extensive numerical adjustments, directly making it difficult for builds such as Blood Mage, which rely on massive life steal for healing, to continue.
In this environment, the rise of No Grenade Mercenary Build is no accident. It avoids the nerfed mechanics of previous versions, relying on the unique ammo type switching and freeze trigger synergy of the crossbow system to achieve low cost in the ancient game and high skill ceiling in the late game.
As the media has analyzed: a good early-game build shouldn’t rely on expensive equipment, but on the readily available ammo mechanics from the story to achieve efficiency. This build perfectly fits this standard.
II. Core Mechanics
The biggest difference between No Grenade Mercenary Build and previous mainstream builds is that this build lacks true normal attacks. Almost all output is performed by loading specific types of ammo. Therefore, its core operation lies in the selection and switching rhythm of ammo types.
Its main output skills revolve around two core ammo types:
1. Permafrost Bolts
Combining damage and crowd control. It has a shotgun-like multi-shot mechanism. When fired at a target at close range, all ammo can hit the same unit, dealing high single-target damage and quickly accumulating freeze stacks.
In boss battles or against high-difficulty rare monsters, Freezing Mark can be used to further accelerate the freezing efficiency, keeping the target frozen for a long time.
2. Fragmentation Rounds
This skill deals massive damage when facing frozen enemies, and the increased damage is converted into frost damage, creating a perfect loop with the freeze accumulation mechanism.
Therefore, the entire skill combo is clear: first, use Permafrost Bolts to inflict the freeze, then immediately use Fragmentation Rounds to detonate the ice and restore health. This is the fundamental reason this build can suppress opponents to the point of near inability to retaliate in boss battles.
Furthermore, the damage potential of this combo can be further increased as your character progresses to Act 3.
Another key maneuver is using Entangle skill to trigger ice wall explosions: with the support of Crystalline Shards gems, stack Impale layers on the frozen target, then frequently trigger piercing damage with Living Lightning summons.
This damage architecture, which combines freezing, stacking piercing, and high-frequency triggering into a three-layered chain, proved incredibly powerful even against the final boss in Patch 0.5.0.
III. Early Game Pace
Having understood No Grenade Mercenary Build’s mechanics, you must also understand how to use it during the ancient game of Path of Exile 2: Return of the Ancients.
The application and equipment requirements differ for each chapter. You’ll need to adjust based on the story and gameplay. Don’t worry, POECURRENCY will plan for you at different stages.
1. Before the First Story Boss
Primarily use Fragmentation Ammo for close-range damage. When confronting clusters of enemies, utilize standard crossbow bolts to keep a safe distance.
Once you enter town, be sure to use keywords like Physical Damage, Health, and Movement Speed in Stat Filters section of the trading post to lock in your core early-game equipment. Movement speed, in particular, is crucial for dodging mechanics in the early game.
2. During Act 1 Progression
Go to the specific lakeside cabin on PoE2 map as soon as possible, activate Alchemy Cauldron, summon the rare monster, and defeat her to obtain a support gem. Use this gem to craft a Double Barrel support gem for Permafrost Bolts.
This means that each of your subsequent shots will become two bullets, effectively doubling the efficiency of freezing enemies.
3. Defeating the Gatekeeper Boss
Defeating Rust King will grant you a level 3 Skill Gem, which can be used to craft Wind Blast and switch your charm to Wyvern Form. Defeating Rotten Druid will guarantee a support gem, which can be used for Permafrost Bolts or Fragmentation Rounds; the difference is minimal.
During this process, you only need to use the above mechanics without making any changes, which is more than enough to deal with Act 1 boss.
However, adjustments are needed in Act 2.
IV. Qualitative Change and Equipment
Act 2 is the starting point for the qualitative change in No Grenade Mercenary Build.
At this stage, POECURRENCY recommends prioritizing projectile damage and dual-wield weapon damage in Passive Skill Tree, and investing in the projectile stun accumulation talent near level 16. This will provide the prerequisite for increased damage from stun triggers in later combat.
Also, in the latter half of Act 2, unlock Galvanic Shards as the main map-clearing skill. With the support of gems like Elemental Armament and Living Lightning, the spark splash effect is enough to achieve a satisfying one-click clear of the entire screen in normal maps.
Regarding equipment, Crossbow is the most crucial.
It is recommended to focus on rare or blue quality weapons with high physical damage and elemental damage affixes at levels 16 and 44. If possible, use POE2 Currency to enchant them. As the main equipment for this build, increasing Crossbow’s damage and level is very important, and will further significantly reduce boss fight time.
In the early game, Currency can only be obtained through monster drops and selling items, which is time-consuming and yields low returns. Even in Act 2, the amount accumulated through gameplay alone is not substantial, not to mention the wide range of uses for Currency.
Therefore, we recommend to buy PoE 2 Currency from POECURRENCY.com. We offer the best prices and fast transaction services, providing an efficient shortcut for players who need a large amount of currency before the mid-game.
Furthermore, the newly introduced Verisium Runeforging system in Path of Exile 2 allows you to add a new defensive type, Runic Ward, to your armor. Prioritizing Runic Ward buffs during the ancient game will significantly improve your survivability.
V. In-Game Data and Endgame Performance
One of the greatest strengths of this No Grenade Mercenary Build is its complete independence from specific Skill Gem levels or legendary items. It merely capitalizes on the intrinsic strengths of the ammo system itself. In actual combat, Mercenary performs exceptionally well against elites and bosses in Act 3 and later:
1. Damage Output
The combination of Frozen + Armor Shatter can inflict excessive pressure on bosses before they enter special phases, frequently freezing them.
Furthermore, when the character acquires Siphon Elements and reduces their aura retention requirements through talents like Ancient Bastion, they can almost simultaneously activate Blessed Auras like Herald of Thunder and Herald of Ice, significantly increasing their clearing speed on normal maps.
2. Survivability
The freeze effect means that most non-immune enemies cannot mount any effective attacks, greatly reducing movement pressure.
Additionally, if the chest armor has Rune Ward affix, it provides a brief layer of absorption when the character’s health is low, allowing for a safe retreat when paired with high movement speed boots.
3. Mobility
WASD movement system is naturally suited to this playstyle.
You can maintain a consistent ammo-switching rhythm while running, instantly casting Permafrost Ammo and Armour Piercing Rounds each time you turn to face an elite enemy, unleashing a high burst of damage before continuing to move, creating a shooting rhythm similar to that in a shooting game.
Many media outlets have also mentioned in their reviews that Mercenary’s Crossbow system, combined with WASD movement, creates a smooth Run-to-Gun loop, which is the most surprising aspect of this class.
VI. Ascendancy Path Selection
In Path of Exile 2 Patch 0.5.0, both Ascendancy paths for Mercenary can currently utilize this build, but with different focuses:
1. Tactician
Suitable for players seeking stable progression. Its key mechanic is halving Spirit retention requirement. After gaining a permanent Spirit source, this effectively provides double Spirit pool compared to a standard build.
You can simultaneously activate multiple Spirits such as Herald of Thunder, Herald of Ice, and Legionnaire Illusion, gaining comprehensive attribute bonuses with extremely low resource costs during the progression of Act 3.
2. Witchhunter
More suitable for players who want to challenge the final boss. Witchhunter’s talents focus more on the ability to finish off powerful enemies. It possesses powerful single-target finishing passives like Culling Strike and Decimating Strike, which naturally align with this build’s style of high burst damage after ice control.
Furthermore, Witchhunter’s unique Sorcery Ward provides extremely high elemental protection even when armor and evasion are lost, offering more tactical flexibility for dealing with the high-frequency elemental damage in high-difficulty maps later in the game.
In short, with the upcoming Path of Exile 2 Return of the Ancients reset and the endgame system overhaul, every player is looking for the most reliable path to progression on May 29th.
Therefore, POECURRENCY believes that whether you want to complete the story as quickly as possible or challenge the new peak boss in Endgame Atlas, you can try the following super-powerful build of constantly freezing and then exploding.
