Among the six currently available classes in Path of Exile 2, the Mercenary stands out as one of the smoothest leveling experiences. Unlike other classes that may struggle against swarms or require constant melee engagement, Mercenaries boast versatile tools to handle nearly any combat scenario.
However, playing a Mercenary effectively demands strategy – certain builds outperform others during the leveling phase. This guide covers essential skills, support gems, item priorities, and passive tree choices to optimize your Mercenary's journey through Path of Exile 2's endgame.
Essential Mercenary Leveling Skills & Support Gems
Mercenary progression starts slow in Path of Exile 2, as many players initially over-rely on basic Crossbow mechanics rather than embracing the class' grenade-focused potential. While Crossbows suffer reload delays, unlocking grenade skills transforms Mercenaries into combat powerhouses.
- Early game focuses on Fragmentation Shot (versatile close-quarters damage) and Permafrost Shot (crowd control through freezing). Boost Fragmentation Shot's effectiveness with Stun-focused Support Gems.
- The mid-game transition introduces explosive capabilities with Gas Grenade (massive poison AOE), Explosive Grenade (timed detonations), and Explosive Shot (combo detonator).
- Supplement with Ripwire Ballista (aggro management) and Glacial Bolt (anti-swarm defense), swapping out earlier skills accordingly.

Crucial Mercenary Passive Skills
Three key passive skills define Mercenary progression:
- Cluster Bombs: Adds projectile count to grenade skills
- Repeating Explosives: Chance for double detonations
- Iron Reflexes: Converts Evasion to Armor, synergizing with Witchhunter Ascendancy
The Witchhunter Ascendancy's Sorcery Ward provides magical defense while halving armor/evasion – making Iron Reflexes' conversion invaluable for maintaining physical damage mitigation.
Prioritize Cluster Bombs first, then detour for Iron Reflexes when reaching the tree's edges near attribute nodes.
Secondary priorities include cooldown reduction, AOE enhancements, and projectile/grenade damage. Crossbow-focused passives become relevant later in the leveling process.
Gear & Stat Optimization
Mercenaries require careful gear curation:
- Crossbow upgrades provide the most significant power spikes
- Balance Dexterity and Strength requirements
- Hybrid Armor/Evasion gear offers optimal defense
- Prioritize damage, resistances, and sustain modifiers
The Bombard Crossbow base type is particularly valuable, adding extra grenade projectiles to skills. Always collect these for potential crafting upgrades.
