The Two-Faced Constructor is a DLC boss in AI Limit: Eirene's Furnace of War that leans heavily on electricity-based attacks at varying ranges. It isn't the fastest enemy you'll face, but its ability to constantly shift between long-range lightning barrages and close-quarters slams makes the fight disorienting if you don't know what to watch for. Most of its moves have a visible wind-up, which means the fight rewards patience and pattern recognition more than raw aggression.
Quick answer: Equip the Holy Ritual (a one-handed long blade with innate electricity damage), stock Mud Balls and healing items, then focus on parrying the Constructor's heavy attacks — particularly the slam and Windmill Lightning — to interrupt its combos and create damage windows.
Two-Faced Constructor Attack Patterns
The Constructor cycles through nine distinct attacks. Learning the visual tells for each one is the single most important thing you can do before worrying about gear or strategy. The boss will mix these freely, and its range changes constantly because it can close the distance at will.
| Attack | Tell / Wind-Up | How to Avoid |
|---|---|---|
| Thunderbolt Barrage | Five small thunderbolts charge in a horizontal line in the boss's hands | Dodge laterally the moment you see the bolts form; they launch quickly once charged |
| Dual Bolts | Boss closes distance fast; hands rise into the air | Quick sidestep dodge as the hands go up — the bolts fire at close range |
| Slam and Swing | One head lifts the other overhead | Back off immediately; after the slam, the two heads swing at each other in a wide arc |
| Wind Push | Sudden gust with minimal warning | Creates forced distance — use the space to heal or reposition rather than trying to dodge through it |
| Double Slam Combo | Boss rises into the air | The ground impact hits twice, followed by a thunderclap; dodge the first impact, then dodge again for the second |
| Orb Lightning | A single orb of lightning forms and launches toward you | Easiest attack to read — sidestep or dodge in any direction |
| Thunderbolt Combo | Both faces create one massive thunderbolt and slam it down, then clap hands | Move away early if you can't interrupt; the clap releases energy followed by a brutal uppercut |
| Wheelbarrow | The two faces hold hands and form a wheel shape | The boss flips sides on the battlefield — reposition quickly to avoid being caught mid-roll |
| Windmill Lightning | Boss spins in the air while gathering electricity | Creates a large AoE on release; back away or interrupt before the spin completes |
Recommended Loadout
The Holy Ritual is one of the strongest weapon choices for this fight. It's a one-handed long blade that carries innate electricity damage, giving you solid DPS without needing to buff your weapon mid-fight. A long blade also provides enough reach to punish the Constructor during its recovery frames without standing dangerously close.
That said, weapon comfort matters more than optimization. If you've been running a spear or greatsword through the DLC and know its timing well, stick with it. Swapping to an unfamiliar weapon for a marginal damage advantage usually costs more than it gains.
For consumables, bring Mud Balls for health recovery along with any throwables you have stockpiled. The fight can drag if you play too passively, and having a reliable healing option lets you stay aggressive during the windows that matter.
Core Strategy — Parry Timing and Interrupts
Quick movement and fast decision-making define this fight more than any single gear choice. You need to constantly read whether the Constructor is setting up a ranged attack (where you dodge) or a melee-range move (where you parry). The two require opposite responses, and the boss switches between them without much warning.
The most important mechanic to exploit is that several of the Constructor's heavy attacks can be interrupted. Right before the slam and the Windmill Lightning, there's a window where landing hits will break the boss's flow and cancel the attack entirely. If you can consistently identify these moments, you cut out the two most punishing moves in the fight.
For attacks you can't interrupt, parrying is your best tool. The Constructor's heavy swings have long, readable animations that give you enough time to activate a parry. Successful parries deal significant posture damage and open the boss up for follow-up combos.
Positioning and Movement Tips
Despite not being the fastest boss in AI Limit, the Two-Faced Constructor's movement is deceptive. It can close gaps quickly with Dual Bolts or the Wheelbarrow flip, and the Wind Push forcibly repositions you. Staying at mid-range — close enough to punish recovery frames but far enough to react to lightning attacks — is the sweet spot.
When the boss uses ranged lightning moves like Thunderbolt Barrage or Orb Lightning, lateral movement handles them cleanly. Don't waste dodge stamina on attacks you can simply sidestep. Save your dodges for the close-range slams and the AoE finishers where precise i-frames matter.
If you get pushed away by the Wind Push, don't rush back in immediately. The Constructor often follows the push with a ranged attack. Wait for that attack to resolve, then close the gap during its recovery.
Electricity Resistance and Gear
Since the Constructor deals almost exclusively electricity damage, wearing your highest Electricity resistance armor makes a noticeable difference. If you've been progressing through AI Limit's base game, the Clergy set offers the best overall Electricity defense among available armor sets. For the DLC specifically, check whatever new armor you've picked up in Eirene's Furnace of War and compare the Electricity resistance values.
Seals that boost Electricity defense are also worth equipping. Even a small reduction in damage taken per hit adds up over a long fight, especially when multi-hit combos like the Double Slam or Thunderbolt Combo can chunk your health bar in seconds.
When You're Struggling
If the fight feels impossible, the issue is almost always one of two things: you're trying to heal at unsafe moments, or you're not recognizing the interrupt windows on the slam and Windmill Lightning. Focus on those two adjustments before changing your build.
Heal only after confirmed safe moments — after dodging the Orb Lightning, after the Wind Push creates distance, or after successfully interrupting a heavy attack. Healing during the Thunderbolt Combo's clap phase or mid-Wheelbarrow will get you killed.
The fight rewards patience. The Constructor's wind-ups are generous by AI Limit standards, and almost every attack leaves a punish window afterward. If you stop trying to force damage and instead wait for those openings, the boss goes down steadily without requiring perfect play.
