Seized Construct Boss Guide — Destroying the Corrupted Sage Mech

The Seized Construct is the boss of the Spirit Temple — a massive ancient Zonai construct that has been corrupted and taken over by Ganondorf's Gloom. The fight is mechanically unique: you are operating Mineru's Construct body and must fight construct-to-construct, exploiting weaknesses in the Seized Construct's limbs using the same arm-type mechanics you mastered during the temple. Understanding arm interactions is the entire fight.

Recommended Preparation

Unlike other bosses, this fight uses Mineru's Construct body as your vehicle. Your personal gear affects survivability if you're dismounted, but the fight is won or lost based on your construct arm inventory.

• Construct Arms loadout (4 slots): Bring a balanced set — at minimum two arm types covering the three core mechanics (Cannon, Flame Emitter, Shock Emitter). The Seized Construct uses all three limb types.
• Arrows (30+) — for Phase 2 long-range targeting when construct movement is restricted
• Gloom-resistant food — if knocked off Mineru, Gloom on the sanctum floor deals rapid damage. Bring 3–4 Sundelion meals (Sunny Fried Wild Greens, etc.) to counteract Gloom-afflicted hearts
• Health food (large restores) — falls from Mineru cost hearts. Have recovery meals for ground phases
• Strong personal weapon — needed if dismounted during Phase 2; Mineru's construct cannot always protect you

Understanding Mineru's Construct Arms

You control Mineru's Construct with interchangeable arms. Each arm type has specific properties:

| Arm Type | Attack | Best Against | |----------|--------|--------------| | Cannon | Explosive projectile burst | Seized Construct's armored leg segments | | Flame Emitter | Sustained fire stream | Ice-coated limbs, mid-range pressure | | Shock Emitter | Electrical arc burst | Wet or conductive segments, stagger | | Construct Arm (basic) | Melee strike | Direct close-range damage after limb breaks |

Key rule: Matching the correct arm type to the Seized Construct's exposed limb vulnerability deals bonus damage and triggers the limb break faster. Using the wrong arm type still deals damage but requires 2–3× more hits for the same result.

The Arena

The Spirit Temple sanctum is a large rectangular Depths chamber. The floor is covered in Gloom — do not touch it on foot. Mineru's Construct legs are immune to Gloom damage; you are not. Stay mounted throughout the fight.

The Seized Construct fills much of the arena. It is larger than Mineru's body — expect its attacks to have wide reach. Keep Mineru's Construct in constant motion to avoid telegraphed slam attacks.

Phase 1 — Four-Limb Combat

The Seized Construct starts with four active limbs: two arms and two leg segments. Each limb has a glowing vulnerability point that pulses when it is the current priority target.

Phase 1 Attack Patterns

Arm sweep: The Seized Construct swings one massive arm horizontally across the arena. The sweep covers roughly 60% of the arena width. Dodge by moving to the opposite side of the arm, or use Mineru's jump to leap over low sweeps.

Double slam: Both arms raise and come down simultaneously at your position. Mineru's jump clears this — time the jump to the moment both arms reach their apex. Landing between the arms during the slam is the ideal positioning for a counter-attack.

Leg stomp cascade: The Seized Construct lifts one leg and slams it down repeatedly in a walking pattern. Keep moving perpendicular to the leg's trajectory. The stomp creates Gloom splash on impact — a brief area hazard around each impact point.

Gloom pulse: The Seized Construct releases a circular Gloom shockwave from its core. The wave travels outward at medium speed. Jump over it or back up rapidly to avoid the leading edge. Contact deals ~1.5 hearts and afflicts Gloom damage.

Targeting and Destroying Limbs

Each limb has a glowing weak point that indicates its active vulnerability:

• Arms: Glow orange-red at the shoulder joint → target with Cannon arm (explosive impact shatters the joint)
• Leg segments: Glow yellow-white → target with Shock Emitter (electrical arc disrupts the construct's movement control)

Procedure for each limb:

1. Identify the glowing vulnerability point on the target limb
2. Select the matching Mineru arm type
3. Fire 3–5 shots into the vulnerability point at close-medium range
4. The limb cracks → fires → breaks off
5. During the break animation, the Seized Construct staggers for 3–4 seconds — use this window for bonus melee damage with basic Construct Arms

After each limb breaks: The Seized Construct recalibrates and activates the next limb's vulnerability. Work through all four in sequence — the order adapts to your positioning, not a fixed rotation.

Efficient approach: Do not overcommit to one limb. If the current target limb is positioned awkwardly (far side, behind the body), bait an attack to reposition the construct closer, then re-engage. Chasing the construct across the arena wastes time.

Phase 1 — Stagger Bonus Windows

After every second limb break, the Seized Construct performs a full stagger — it collapses forward or sideways and its core glows briefly. During this stagger:

• The core is reachable by Mineru's basic Construct Arms
• 2–3 melee strikes on the core deal significant bonus damage
• The stagger lasts approximately 5 seconds — move fast

Phase 2 — Aerial Reconstruction

At approximately 50% health (after all four limbs are broken or severely damaged), the Seized Construct collapses, then rapidly rebuilds itself into a floating aerial form. The reconstructed body is smaller and faster than Phase 1, with repaired Gloom-cannon limbs replacing the broken segments.

Phase 2 New Attack Patterns

Gloom cannon barrage: The Seized Construct's new arm form fires concentrated Gloom projectile volleys at Mineru's position. These track briefly before locking onto the impact point. Dodge sideways — the tracking radius is limited and straightforward lateral movement avoids most shots.

Aerial spin: The Seized Construct spins its arm array at high speed, generating a ring of Gloom energy that expands outward. Jump or retreat to the arena edge before the ring reaches Mineru's position.

Descent slam: Phase 2 ends several attack sequences with a downward slam — the construct drops its entire mass onto Mineru. The shadow precedes the slam by ~2 seconds. Sprint away from the shadow and prepare for the rebound opening.

Phase 2 — Targeting the Core

In Phase 2, limbs are no longer the priority. The Seized Construct's core is now directly exposed at its center — the Gloom-crystal body is visible and targetable.

Ground-level targeting:

1. Position Mineru directly below the hovering construct during its attack sequences
2. Fire Cannon arm shots upward into the core during the brief pauses between attack volleys
3. 3–4 direct core hits stagger the construct and bring it momentarily lower

Arrow targeting (efficient Phase 2 method): Dismounting briefly to use arrow aim is viable in Phase 2 if the Gloom floor is managed. However, staying mounted and using Cannon arm projectiles is safer and nearly as effective.

Phase 2 exposure windows:

• After the descent slam, the construct lingers at low altitude for 2–3 seconds — this is the best close-range Cannon arm window
• After the aerial spin attack completes, the spin arms retract briefly — fire into the exposed core during retraction
• After a Gloom barrage sequence, the construct pauses to reload — fire Shock Emitter shots for stagger bonus during this pause

Phase 2 Ending the Fight

Once the core has taken sufficient damage from Phase 2 targeting, the Seized Construct begins a final collapse sequence. Continue firing until the health bar depletes — do not let up. The construct does not have a Phase 3.

Final damage tip: If you have Shock Emitter remaining, the combined cannon-and-shock approach deals maximum damage per second during the final exposure windows. Use Cannon on the core, follow immediately with Shock Emitter burst — the double-hit stagger chains into another opening.

Seized Construct Lore

The Seized Construct was originally a guardian-class Zonai war machine, built during the ancient Zonai civilization's height to protect the Spirit Temple's sacred mechanisms. When Ganondorf's Gloom spread through the Depths after his awakening beneath Hyrule Castle, it found the Seized Construct in a dormant maintenance state within the Spirit Temple. Gloom energy cannot control organic life directly, but Zonai construct architecture — being essentially a mechanical system with no will of its own — is vulnerable to Gloom corruption acting as a signal override. The Construct's original Zonai command protocols were overwritten by Gloom, turning it into an aggressive temple guardian hostile to any approach. Mineru — the original designer of this construct class — recognizes the underlying architecture even through the corruption, which is why her Construct body's arms are specifically effective: they operate on the same Zonai frequency as the Seized Construct's limb joints, allowing precision targeting that other weapons cannot achieve.
