Nautilon modules

What can a Nautilon upgrade module raise? The submarine has two families, from C to S: the Humboldt Drive and the Nautilon Cannon, and an S-Class Humboldt Drive upgrade raises all three of its stats.

Each stat reads as the module's card prints it. The land exocraft share a set of their own, with a page each: the Roamer, Nomad, Pilgrim, and Colossus.

Every Nautilon module

The quest Dreams of the Deep gives the Nautilon Chamber, where the submarine is built, and the High-Power Sonar, which is also a blueprint of the Space Anomaly.

Module	What it does	Built from
Humboldt Drive	A thermally-efficient, inversion-proof reactor engine capable of powering the Nautilon even at extreme depths.
Osmotic Generator	Installed into the drive system aboard the Nautilon Submarine.	Chromatic Metal ×150, Living Pearl ×6, Solar Mirror ×2
Nautilon Cannon	A mounted cannon specifically designed for the Nautilon Submarine.	Chlorine ×100, Crystal Sulphide ×6, Living Pearl ×2
Tethys Beam	A mounted laser system specifically designed for the Nautilon Submarine.	Magnetised Ferrite ×50, Chlorine ×100, Living Pearl ×10
Dredging Laser	Adds Terrain Manipulation capability to the laser systems of the Nautilon Submarine.	Magnetised Ferrite ×80, Lithium ×90, Crystal Sulphide ×4
High-Power Sonar	A high-detail sonar device, capable of upgrading the scanner technology aboard a Nautilon-class submarine to Analysis Visor levels, pinning to the HUD all information typically revealed by the Analysis Visor.	Solar Mirror ×1, Crystal Sulphide ×3, Ferrite Dust ×50

Every nautilon module the game lists, apart from upgrade modules.

Supercharged slots

The Nautilon has three supercharged slots, and they stand in the same places for every player: slot 5 of the top row, slot 2 of the middle row, slot 8 of the bottom row, counting from the left. There is nothing to roll. None of the three is adjacent to another, and the Nautilon has only two kinds of upgrade module: give one slot to the Humboldt Drive and one to the Nautilon Cannon, set the rest of each kind and its own technology around it, adjacent, and give the third slot to one more module of the kind you use most. Standing apart, that module loses the adjacency bonus of its own kind but keeps the supercharge, which is worth more.

Upgrade modules

One table per family: each class, how many stats one install raises, and the limits of each stat. Below each table a second one shows what one install rolls: how many stats it raises, how often it comes near the best its kind can add to the stat it names, and how often each stat is raised; a third shows how often a raised stat lands in the top tenth of its limits.

Humboldt Drive

Module	Stats raised	Fuel Usage	Top Speed	Acceleration
C-Class	1	-1% to -11%	+2% to +4%	+10% to +15%
B-Class	1 to 2	-11% to -15%	+4% to +6%	+15% to +20%
A-Class	2 to 3	-15% to -25%	+6% to +8%	+20% to +25%
S-Class	3	-15% to -31%	+8%	+25% to +30%

Humboldt Drive upgrade modules, their limits as the game's card prints them. Stats raised is how many stats one install shows on its card.

Module	Stats raised	Near best Top Speed	Fuel Usage	Top Speed	Acceleration
C-Class	1	3.6%	33.4%	33.4%	33.2%
B-Class	1: 90% 2: 10%	6%	36.7%	36.7%	36.6%
A-Class	2: 84% 3: 16%	21.2%	72.1%	72%	72%
S-Class	3	—	100%	100%	100%

What one install of each Humboldt Drive upgrade module rolls, exact over every install. Stats raised: how often its card shows each number of stats. Near best: how often it adds at least nine tenths of the most Top Speed any install of its kind adds, a dash where Top Speed has one value. Each stat: how often an install raises it.

Module	Fuel Usage	Top Speed	Acceleration
C-Class	5%	5.3%	5.6%
B-Class	5%	5.2%	5.5%
A-Class	5.2%	5.2%	5.3%
S-Class	5.2%	—	5.2%

How often a raised stat of each Humboldt Drive upgrade module lands in the top tenth of its limits, a dash where the module has no such stat or the stat has one value.

Nautilon Cannon

Module	Stats raised	Damage	Rate of Fire
C-Class	1	+1% to +3%	+1% to +3%
B-Class	1 to 2	+3% to +6%	+3% to +6%
A-Class	1 to 2	+6% to +9%	+6% to +7%
S-Class	2	+9% to +12%	+7% to +11%

Nautilon Cannon upgrade modules, their limits as the game's card prints them. Stats raised is how many stats one install shows on its card.

Module	Stats raised	Near best Damage	Damage	Rate of Fire
C-Class	1	5.2%	50%	50%
B-Class	1: 90% 2: 10%	5.8%	55.1%	54.8%
A-Class	1: 84% 2: 16%	9.5%	58.1%	57.9%
S-Class	2	22.6%	100%	100%

What one install of each Nautilon Cannon upgrade module rolls, exact over every install. Stats raised: how often its card shows each number of stats. Near best: how often it adds at least nine tenths of the most Damage any install of its kind adds, a dash where Damage has one value. Each stat: how often an install raises it.

Module	Damage	Rate of Fire
C-Class	5%	2.5%
B-Class	5%	2.5%
A-Class	5%	2.5%
S-Class	5.2%	2.6%

How often a raised stat of each Nautilon Cannon upgrade module lands in the top tenth of its limits, a dash where the module has no such stat or the stat has one value.

The last exocraft walks on legs, and the Minotaur has a set of its own.
