How many collectibles are in the Terra Dome in Pragmata?

The Terra Dome contains 47 collectibles across 5 sub-areas: Terra Dome Entrance (10), Eco Modeling Lab (13), GeoScience Lab, Soil Research (13), and the Terrarium (2 items, both from the Red Zone). Safe Boxes 8 and 9 plus Pure Lunum 3 require the Cleansing ability from Sector 5 to reach. Nothing is permanently missable.

How do I beat the Garden Keeper boss in Pragmata?

The Garden Keeper has 3 weak points: head (least damage), underside (middling), tail (most damage). Prioritise the tail whenever accessible — especially during the Tail Shock Explosion when the tail stays planted in the ground. Dodge the Wide Tail Spin LATE, not early. At below 50% HP, the boss mounts arena walls and gains Lightning Strikes and Aerial Tail Lasers — use Code Generator and Sticky Bombs for the expanded hacking matrix, and redirect homing missiles back at the boss with Diana.

What are Gen Chips in Pragmata's Terra Dome?

Gen Chips are collectible items in the Terra Dome that fuel tree-printing terminals. When inserted into a terminal, Diana prints a tree branch or platform you can jump across to progress. There are 4 Gen Chips in the sector, spread across the Eco Modeling Lab and related areas. Collecting all four is required to activate both Lim Regulators and unlock the path to the Garden Keeper.

Where is the only Storage Expander in the Terra Dome?

The Terra Dome's only Storage Expander is found in the Terrarium Red Zone. Complete the Red Zone challenge to receive both the Storage Expander and a Pure Lunum as rewards. This is the only Storage Expander in the entire sector, so do not skip this Red Zone.

Before You Enter

The Terra Dome is a dramatic change of setting from the Mass Production Array: a dense artificial forest environment that recreates Earth's flora using Lunafilament. The sector introduces two new enemy types and a unique puzzle mechanic — Gen Chips — that gates progression throughout.

★ New Mechanic — Gen Chips

Gen Chips are collectible items scattered through the sector. When inserted into tree-printing terminals, Diana uses them to generate branch platforms that let Hugh traverse gaps or reach new areas. There are 4 Gen Chips in the sector — finding them is tied to unlocking both Lim Regulators, which is the sector's main objective. Always check side rooms and platforms when the path seems blocked.

Shelter prep · Spend your Shelter License Key #2 rewards first. Unlock the Associate Board at Cabin's Stamp Club. Upgrade Diana's Hacking to Tier 2 if possible — the SectorGuard rematch mid-sector is easier with improved hacking speed. Bring the Decoy Generator and Code Generator; both are valuable throughout this sector and for the Garden Keeper boss.

New enemies · Lancer: agile full-sized bot that closes range fast, first seen in the outdoor entry area. Invisible enemies: appear in Soil Research — impossible to see until they attack. Dodge at the last second when they grab — that is when they fully reveal themselves and become hackable.

Holo-Walls · The Terra Dome contains more hidden Holo-Walls than any previous sector. If a room looks too empty, scan the walls — many Safe Boxes are behind panels that look identical to solid walls. Use Diana's Object Scan after every combat encounter.

// Sub-Area 1 · 10 Collectibles

Terra Dome Entrance

1

After arriving by tram and crossing the bridge, you encounter a Lancer — the new enemy type for this sector. They're fast and aggressive; hack quickly to expose the core, then use the Grip Gun or Charge Piercer. More Lancers appear throughout the sector.

2

Before entering the main building, look left and jump to the box suspended by a crane. From the box, jump to the white platform, then right onto the grassy ledge — Safe Box 1 is there. This is the easiest collectible in the sector to miss because it's outdoors before the "real" sector begins.

3

Inside the building, IDUS triggers and roots overgrow the facility. The path from the main elevator splits into two routes (A and B). Both must be completed — take whichever first. Safe Boxes 2 and 3 are at the end of each branch; Safe Box 4 is between the two exits.

4

Find Escape Hatch 1 in the room where the cutscene with shrinking branches plays (before IDUS interrupts). Take the left route from the main elevator first to find it.

REM 1 (Flowers): Ride the elevator up from near the Soil Research entrance. Mod 2 (Precision Shot) is on a ledge at the top. Drop back down to find REM 1 (Flowers) directly beneath the Mod. Drop further left to reach Safe Box 5. All three items use the same elevator — don't miss the drops back down.

S2

// Sub-Area 2 · 13 Collectibles (Densest)

Eco Modeling Lab

1

The Eco Modeling Lab introduces the Gen Chip system. The first terminal requires one Gen Chip to grow a tree platform. Find it in the lower section just below the first terminal. After inserting it, a branch grows — jump across to continue.

2

Mini Cabin 1 is in the room with the tree-growing terminal — look up at the tree branches above the terminal on the right side. Shoot it before inserting the Gen Chip (the branches change after activation).

3

After creating the first tree platform: do not go left through the door immediately. Instead, go right — there's a Holo-Wall hiding Safe Box 6. This is the most frequently missed item in the sub-area.

4

Find Escape Hatch 2 in the room where you grow multiple branches to cross a gap. Right next to it is the entrance to the Terrarium Red Zone — clear it for the sector's only Storage Expander + Pure Lunum 2 (see Terrarium section).

5

The second set of terminals requires 3 Gen Chips. One is on a raised platform guarded by an enemy. Another is on the lower level down a passage. The last is inside an interior area. After activating both Lim Regulators, you return to the central area and take the elevator upward.

6

You then face a SectorGuard Rematch — functionally the same fight as Sector 1, but now accompanied by two Lancers. Eliminate the Lancers first to make the fight manageable. Use Confuse and Multihack hacking nodes if you have them unlocked.

Backtrack items here: Several Safe Boxes in the Eco Modeling Lab area are blocked by dead filament. Cleansing required — Sector 5

S3

// Sub-Area 3 · Safe Boxes + REMs

GeoScience Lab

1

Access via the elevator from the Eco Modeling Lab. As the elevator descends, swing right immediately — there is a hidden room behind a Holo-Wall containing a Safe Box. Many rooms in this sub-area look empty but conceal Safe Boxes this way.

2

In the soil research area: look for an orange pipe and head behind it to find items. Continue through the area clearing enemies and finding the scattered Safe Boxes behind Holo-Walls and inside side rooms. Always scan walls after combat encounters end.

3

Find the Swing REM — past a Lunafilament barrier (Lim Eraser), through a hacked door, at the end of a path on the left side. Back at the Shelter, give it to Diana at the Replicator — a swing appears in the Shelter and she reacts to it.

4

Activate Escape Hatch 4 at the top of the elevator, in front of the locked door. This is the GeoScience Lab Station fast-travel point — use it to return to the Shelter for upgrades before continuing to Soil Research.

Holo-Wall density: GeoScience Lab has the highest concentration of Holo-Walls in the sector. If Diana's Object Scan shows there should be more items nearby but you can't find them, check every wall surface — especially at T-junctions and at the end of short corridors.

S4

// Sub-Area 4 · 13 Collectibles

Soil Research

New enemy — Invisible: Soil Research introduces invisible enemies. You cannot see them until they initiate an attack. Dodge at the last second when they go for a grab — that is the exact moment they reveal themselves and become hackable. Dodging too early will miss the reveal window. Listen for audio cues: their movement creates faint sounds.

1

Enter from the door labeled Soil Research. The path splits immediately — take the right fork first. Safe Box 11 is at the dead end of the right path.

2

On the beach section: after the cutscene, turn right and use the Lim Eraser on the filament mass, then drop down the hatch below. Inside is a broken Cabin holding Training Data 2. From the surface, use the rocks to reach the high metal platform — follow the Lunafilament string down to a lower cave ledge for another Safe Box.

3

After the invisible enemy fight area, take the elevator up. Once on the balcony, look left into the trees — Mini Cabin 2 is sitting in the tree canopy. Shoot it from the balcony.

4

Hack the four-lock door to unlock it (four separate terminals in the area). Behind it is Escape Hatch 5. After the next elevator descent, immediately check right for a Holo-Wall hiding Safe Box 14.

5

Deactivate the jammer in the area to reveal Safe Box 15. Continue through to reach the Terrarium section where the final boss awaits.

Cleansing backtrack items: Safe Box 8, Safe Box 9, and Pure Lunum 3 are behind dead (red) filament barriers. Cleansing required — Sector 5. These three items are the reason you'll need to return to Terra Dome after Sector 5.

S5

// Sub-Area 5 · 2 Collectibles (Red Zone) · Boss Arena

Terrarium

The Terrarium is the final sub-area and the smallest — it contains only 2 collectibles, and both are gated behind the Terrarium Red Zone.

⚠ Terrarium Red Zone — Do Not Skip

The Red Zone is located near the Cultivation Lab Station Escape Hatch. Complete the challenge to receive:

▸Storage Expander — the only Storage Expander in all of Terra Dome. Directly increases Diana's Hacking Gauge capacity.
▸Pure Lunum 6 — rare upgrade material needed for high-tier weapon upgrades.

Before the boss: After the Red Zone, find the Cultivation Lab Station Escape Hatch. Return to the Shelter to fully stock up before proceeding. The boss arena is accessed by dropping through a hole in the ground — once you drop in, the fight begins immediately. Do not drop in accidentally.

// End of Sector 3

Boss: Garden Keeper (on-screen: "Large Bot")

A fast, scorpion-shaped mech with huge range. Unlike the slow Creator, the Garden Keeper closes distance in one leap and punishes impatient players hard. The fight rewards patience and precise dodge timing above all else.

Boss Strategy

Need the dedicated fight page instead of the route summary? Open the Garden Keeper boss guide for tail priority, dodge timing, and late-phase pressure notes.

Recommended Loadout

▸Shockwave Gun — close burst when tail or head is exposed

▸Code Generator — reduces Phase 2 hacking matrix complexity

▸Sticky Bombs — additional hacking matrix relief in Phase 2

▸Decoy Generator — redirect boss attention during hacking

Pick up extra Shockwave Gun and Code Generator ammo scattered around the arena before triggering the fight.

Weak Points

Weak Point	Damage	Best Window
Tail	Most damage	Tail Shock Explosion — tail stays planted for several seconds. Dump everything into it.
Underside / Chest	Middling	When boss is stunned or after dodge. Harder angle.
Head	Least damage	Always exposed after hack. Easy to hit.

Phase Breakdown

Phase 1 — 100% → 50% HP

▸Leaping Pincer Swipe: Most common attack. Chains into a second swipe or Arm Slam. Stay mobile after the first hit.

▸Wide Tail Spin: Dodge LATE — not when the animation starts. Wait until the tail is nearly on you. Early dodges still connect.

▸Tail Shock Explosion: Boss stabs tail into the ground and it stays planted. This is your primary damage window — hit the tail continuously until it pulls out.

▸Shock Mines: Boss plants mines across the arena. Contact freezes Hugh and leads into a Trapped Tail Grab — escape via Diana's hacking minigame. Avoid standing in them; hack mines when the boss is on top of one to stun it.

Phase 2 — Below 50% HP

▸Lightning Strikes: Boss stands still and raises its tail, raining strikes across the arena for several seconds. Keep moving.

▸Aerial Tail Lasers (Wall Phase): Boss mounts the arena walls and fires a prong laser that spreads outward — it cannot be cancelled. Dodge the spread until the attack ends on its own. The tail is hard to reach from this angle — target the belly or head instead.

▸Homing Missiles (Wall Phase): During the wall phase, use Diana to redirect missiles back at the Garden Keeper. This damages both HP and the heat-up gauge.

▸Expanded Hacking Matrix: The matrix grows and fills with impassable and error nodes. Use Code Generator + Sticky Bombs to manage complexity. Overdrive Protocol also clears a full panel if the gauge is ready.

Reward: Defeating the Garden Keeper drops Shelter License Key #3. Return to the Shelter to unlock Tier 3 upgrades at the Firmware Updater and Unit Printer, and the Specialist Board at Cabin's Stamp Club. The next sector — Lunum Mines — is now accessible on the tram map.

// Hidden Collectibles

Mini Cabin Figures — All 3 Locations

Shoot to collect. No Object Scan detection. Listen for "ta-da" sound.

1

Eco Modeling Lab — tree branch above the Gen Chip terminal

In the room with the terminal that grows the first tree platform. Before inserting the Gen Chip, look up at the tree branches on the right side of the room — the Mini Cabin is perched on one of them. Shoot it from the ground.

2

Soil Research — tree to the left from upper balcony

After defeating the invisible enemy, take the elevator up to the balcony. Run along the balcony and look left into the tree canopy — the Mini Cabin is in the branches. Shoot it from the balcony ledge; you have enough range.

3

Soil Research / GeoScience area — on a vine in outdoor section

In an outdoor area near a locked door, a vine climbs the wall across from you. Reach it via the upper walkway — the Mini Cabin is hanging on the vine. You'll pass this area naturally during story progression; look at the vines when you cross the gap.

Terra Dome FAQ

How many collectibles are in the Terra Dome?

Terra Dome contains 47 collectibles — the largest haul in the early game. They're spread across 5 sub-areas: Entrance (10), Eco Modeling Lab (13), GeoScience Lab, Soil Research (13), and Terrarium (2, both from the Red Zone). Safe Boxes 8 & 9 plus Pure Lunum 3 require the Cleansing ability from Sector 5.

What are Gen Chips and how do I use them?

Gen Chips are items scattered through the Terra Dome. When collected, they can be inserted into tree-printing terminals — Diana uses them to grow branch platforms that let Hugh cross gaps or reach new areas. There are 4 Gen Chips in the sector; collecting and using all four is required to activate both Lim Regulators and unlock the path to the Garden Keeper.

Where is the Storage Expander in Terra Dome?

The Terra Dome's only Storage Expander is inside the Terrarium Red Zone, near the Cultivation Lab Station Escape Hatch. Complete the Red Zone challenge to receive both the Storage Expander and Pure Lunum 6 as rewards. Do not skip this Red Zone.

How do I fight invisible enemies in Soil Research?

Invisible enemies cannot be seen until they attack. Dodge at the last second when they initiate a grab — this is the exact moment they fully reveal themselves and become hackable. Dodging too early misses the reveal window. Listen for audio cues: their movement generates faint sounds before the attack connects.

How do I beat the Garden Keeper?

Target the tail — it deals the most damage of the 3 weak points. The best opportunity is during the Tail Shock Explosion when the tail stays planted in the ground. For the Wide Tail Spin: dodge late, not when the animation starts. Below 50% HP, the boss mounts arena walls and the hacking matrix expands — use Code Generator + Sticky Bombs for the matrix, and redirect homing missiles back at the boss with Diana.

Is there a mid-sector boss in the Terra Dome?

Yes. In the Eco Modeling Lab, after collecting Gen Chips for the second regulator, you face an enhanced SectorGuard — functionally the same fight as Sector 1, but now accompanied by two Lancers. Eliminate the Lancers first using Confuse or Multihack nodes, then handle the SectorGuard the same way as before.
