Path of Exile 2 Patch 0.5 ("Return of the Ancients", Runes of Aldur league) delivers one of the most impactful Mercenary reworks to date, fundamentally reshaping crossbow scaling, ascendancy identity, banner systems, and passive tree structure.
This update pushes Mercenary builds toward higher mechanical depth while simultaneously simplifying core damage loops through quality-of-life changes such as zero-base mana cost crossbow skills and redesigned rage/banner mechanics.
For players optimizing progression or trading upgrades, efficient gearing paths often intersect with the broader Path of Exile 2 economy, where PoE 2 Currency plays a central role in early mapping power spikes and endgame scaling.

Ascendancy | Change Type | Impact |
Gemling Legionnaire | New defensive + gem scaling system | Adds Virtuous Barrier + hidden gem quality scaling |
Witchhunter | Defensive nerf | 50% reduced armor/evasion penalty (increased squishiness) |
Key Highlights
• Crystalline Potential removed
• New notable: Essence of Virtue
• Grants Virtuous Barrier
• Absorbs attribute "Motes" (STR/DEX/INT)
• Loses motes when hit → dynamic defense system
• Advanced Thaumaturgy rework
• No longer grants a skill
• Now adds hidden universal gem quality effects
• Witchhunter: Obsessive Rituals nerf
• Now 50% less armor/evasion (previously 35%)
Category | Change |
Companion nodes | +19 new passives |
Life sustain | +9 life recoup nodes |
Jewel connectivity | Multiple cluster disconnects |
Hybrid scaling | New Archon of Undeath cluster |
Keystone | New Effect |
Trusted Kinship | +30% companion reservation efficiency |
Ancestral Bond | Totems cost no mana, +75 spirit each, doubled cap |
Vaal Pact | 50% increased leech, disables other recovery |
• Craving Slaughter
• Replaced stacking rage system
• Now: +15 max rage for 20s after Glory skill
• Goring
• No longer reduces max life
• Now grants:
• +3% max life
• +20% life leech effect
Patch 0.5 introduces a foundational mechanical overhaul:
System | Old | New |
Mana Cost | Full cost | 0 base cost |
Cost scaling | Fixed | External modifiers apply |
Fragmentation Rounds | % damage scaling | +2 fragments per quality |
Mirage support | Limited | Now supports channeled skills |
Key Implications
• Enables hybrid cost scaling builds
• Makes support gem economy more flexible
• Greatly increases AoE scaling ceiling for Fragmentation builds
This remains the most stable leveling archetype due to:
• Freeze-based control loop
• High burst shotgun damage
• Smooth scaling into endgame
Skill | Function |
Permafrost Bolts | Freeze + control |
Fragmentation Rounds | Burst shotgun DPS |
Galvanic Shards | AoE clear |
Glacial Bolt | Ice wall scaling |
Act | Key Unlocks | Purpose |
Act 1 | Fragmentation Rounds + Permafrost Bolts | Early freeze burst |
Act 2 | Galvanic Shards + Tactician Ascendancy | Mapping transition |
Act 3 | Glacial Bolt + Biting Frost | Boss scaling spike |
Act 4 | Fork + Double Barrel upgrades | Full screen clear |
• Double Barrel → burst scaling
• Elemental Armament → universal scaling
• Living Lightning → hybrid AoE layering
• Fortress → defensive stability
Build | Role | Strength |
Gemling Legionnaire Quality Stacker | Scaling DPS | Endgame scaling ceiling |
Witchhunter Banner Rage Build | Burst + sustain | Consistent boss damage |
Companion Mercenary | Hybrid summoner | Passive map control |
Mirage Archer Plasma Blast | Single-target DPS | Highest boss melt potential |
Fragmentation Grenade Build | League starter | Explosive AoE clearing |
• Hidden gem quality scaling via Advanced Thaumaturgy
• Barrier system via Virtuous Barrier
• Attribute mote cycling defense
Slot | Priority Stats |
Crossbow | Physical DPS + gem quality |
Armor | Life + defense + gem scaling |
Rings | Resist + attack speed |
Boots | Movement speed |
• Banner rotation every ~6–7 seconds
• Permanent rage uptime via Craving Slaughter
• Fragmentation Rounds
• Snipe
• Plasma Blast
• Banner trio (Defiance, Dread, War)
• Significant defensive penalty from Obsessive Rituals
• Requires stronger gear investment
• 19 new companion passives
• Trusted Kinship rework removes defensive penalty
• Spirit stacking gear
• Companion gem level scaling (40–84% increased damage)
This build effectively shifts damage responsibility to summons while the player maintains utility pressure via crossbows and banners.
• Mirage Archer now supports channeled skills
• Plasma Blast duplication doubles beam output
• Extremely high sustained single-target DPS
• Strong synergy with gem quality scaling systems
As Mercenary builds scale heavily with weapon quality, gem levels, and crafted modifiers, progression efficiency often depends on early access to key gear upgrades.
Many players accelerate this process using buy Path of Exile 2 Currency strategies or trading routes within the in-game economy, especially during early league transitions where crossbow bases and support gems fluctuate heavily in value.
Patch 0.5 transforms Mercenary into a highly modular archetype built around:
• Crossbow system flexibility (0 mana cost foundation)
• Rage/banner synergy reworks
• Gem quality scaling mechanics
• Companion and mirage support expansion
• Stronger but more complex defensive tradeoffs
The result is a class with significantly higher ceiling potential, but also more demanding optimization paths across leveling, gearing, and endgame scaling.
