Among the various classes in Endgame phase of Path of Exile 2 Patch 0.5 Return of the Ancients, Gemling Legionnaire has consistently ranked among the top in terms of strength and feel, mainly due to its numerous powerful builds available to players.
There is one less mainstream build that achieves extremely high damage output and exceptional mobility by stacking massive amounts of Mana and relying on specific equipment: Mana Stacker Temporalis Build.
I will now detail this build from multiple perspectives, including gameplay mechanics, equipment, and Passive Skill configuration.

Core Mechanics
The core mechanic of Mana Stacker Temporalis Build in Path of Exile 2 Patch 0.5 lies in the player's ability to cleverly utilize Gemling Legionnaire skills and Passive Skills to convert Mana into damage and defense.
Damage Conversion
Converting Mana into damage primarily relies on Archmage skill. It is a buff skill whose core effect is: based on your maximum Mana value, apply additional Lightning Damage to spells. Therefore, this skill allows players to convert Mana into lightning damage.
Furthermore, to maximize the benefits of Archmage, you can link it with support gems like Lightning Mastery Gem to further increase lightning damage.
Defense Conversion
Simultaneously, players can also use Passive Skills to convert Mana into defense, enhancing their survivability.
This is primarily achieved through Mind Over Matter. This is a Keystone Passive on Passive Skill Tree, and its effect is: when you take damage, a portion of the damage will be deducted from Mana first, instead of Life. This means Mana pool becomes the character's second health pool.
Additionally, you'll need a Keystone Passive Eldritch Battery. It converts all your Energy Shields into additional Mana. This effectively alleviates Mana pressure.
By combining these two Energy Shields, you can build an extremely large effective health pool, which is why you can survive in high-difficulty maps even with low elemental resistance.
Damage Boost Core
To maximize damage, this build cleverly utilizes Keystone Passive Pain Attunement and Low Life mechanic from PoE 2 Patch 0.5.
Pain Attunement grants a 30% bonus to critical strike damage when character is in Low Life.
Therefore, players can reliably trigger this massive damage boost by actively sacrificing some life through specific support gems (such as Atziri's Communion or Her Declaration) to force themselves into Low Life.
Mana Sustain
This build is highly reliant on Mana, making it easy to run out of mana in combat.
To avoid this, you need a crucial mana-regenerating skill - Mana Remnant.
It generates Mana Orbs when the player lands a critical strike or kills. Picking up Mana Orbs not only restores a significant amount of mana but also grants additional shields or damage.
Gear Configuration
In PoE 2 Patch 0.5, gear is a crucial component of builds, and Mana Stacker Temporalis Build is no exception.
The gear for this build is generally quite expensive; you'll need sufficient Path of Exile 2 Currency to acquire it.
Core Gear: Temporalis
Temporalis is one of the core elements of this build. It possesses a special affix that reduces cooldowns by up to 2 seconds - virtually allowing most skills to be cast instantly.
This affix is also the reason for the build's high mobility. Gemling Legionnaire's Blink ability originally had a long cooldown, but with Temporalis, the cooldown is reduced to nearly 0.1 seconds, allowing players to virtually teleport infinitely.
However, matching its power comes a significant challenge. Players must defeat boss Zarokh, the Temporal, without taking any damage while equipped with The Last Flame.
Other Equipment
Besides the core equipment, you can also use the following equipment to complete this build:
First, Runeseeker's Call. Its greatest value lies in its ability to increase the effect of socketed Runes by 200% and provide 5 hidden Rune slots.
Second, Mnemonic Ring. This ring not only effectively increases casting speed and Mana regeneration but also provides elemental resistance.
Third, Mageblood. It is one of the most well-known universal belts in PoE 2 Patch 0.5. It not only automatically uses Flasks but also provides a permanent boost to casting speed, resistance, and movement speed. This further enhances map clearing efficiency.
Fourth, regarding Gloves and Boots, players only need to choose equipment with key affixes: players need to wear Gloves with penetration affixes, which effectively increases the character's damage; for Boots, players need to wear equipment with movement speed bonuses.
However, due to the effect of Temporalis, movement speed is no longer important, so boots are not a priority.
Jewels and Ascendancy Skills
Besides the aforementioned mechanics and equipment, players can further refine their build through some core Jewels and Ascendancy Skills.
For Jewels, Split Personality Ruby is recommended. This is a very well-known Jewel in PoE 2 Patch 0.5, granting players a significant amount of additional attribute points.
In addition, players need to stack Jewels that provide effects such as mana regeneration on kill, critical strike damage, and spell critical strike chance.
For Ascendancy Skills, Enhanced Effectiveness, unique to Gemling Legionnaire, is recommended. It doubles the bonuses provided by the player's Strength, Dexterity, and Intelligence.
This concludes the detailed introduction to the less common Gemling Legionnaire build in PoE 2 Patch 0.5 Return of the Ancients - Mana Stacker Temporalis Build.
It's worth noting that this build may change with patch updates, so players need to pay close attention to patch update information. We recommend players follow EZG Facebook; we'll provide the latest game news and host giveaways from time to time. You can also @friends to participate.
In short, if you're a Gemling Legionnaire player and tired of usual builds, give this one a try.
