Expedition Fleet Composition & Support Mechanics

This page explains how fleet composition affects Expedition results in a player-friendly way.

All bonuses use diminishing returns and have maximum caps.

1. Return Type Specialist Ships (Max +10%)

Certain support ships increase the chance of specific reward types.

Only one specialist ship type applies per reward roll. If multiple specialist ships are present, only the one matching the rolled reward type is used.

Reward Type	Specialist Ship	Effect
Relics	Orbital Refinery	Increases relic discovery rate (up to +10%)
Monuments	Advanced Recycler	Increases monument discovery rate (up to +10%)
Nano	Planetary Harvester	Increases nano discovery rate (up to +10%)
Tech Boosts	Frigate	Increases tech boost discovery rate (up to +10%)

How it scales:

Sending more of the matching ship increases the bonus.
The bonus grows quickly at first.
After large numbers, gains become smaller (diminishing returns).
The maximum possible bonus is +10%, even with 1000 ships.

This encourages balanced fleets instead of extreme stacking.

2. Probe – Find Chance Bonus (Max +10%)

Probes increase the overall chance of finding anything during an expedition (events, resources, ships).

More Probes = higher chance.
Gains slow down at high numbers.
Maximum bonus: +10%.

Probes affect whether you find something at all, not what type.

3. Exploration Ship – Quantity & Quality Bonus (Max +100%)

Exploration Ships improve:

The amount of resources or ships found.
The quality tier of rewards.

This bonus increases logarithmically:

Early ships give strong improvements.
Each additional ship adds less than the previous one.
Maximum bonus: +100%.

Example progression:

1 ship → noticeable improvement
10 ships → strong improvement
100 ships → very high improvement
1000 ships → reaches cap

Exploration Ships affect both quantity and reward quality.

4. Combat Ship Discovery Logic

Combat ships influence which ships can be discovered.

Sending lower-tier combat ships limits discoveries to similar tiers.
Sending higher-tier ships unlocks higher-tier discoveries.

Examples:

Sending Kamikaze allows discovery of Kamikaze or Fighter-class ships.
Sending Battleship enables finding Destroyers or Frigates.

5. Overall Fleet Size Impact

Larger fleets:

Discover more total resources.
Recover more ships.

Fleet size improves volume, but does not bypass caps.

6. Cargo Requirement

Cargo ships are required to bring back discovered rewards.

If you do not send enough cargo capacity:

Excess resources are lost.
Excess recovered ships cannot return.

Always ensure sufficient cargo space.

7. Stacking Rules Summary

• Probe bonus increases overall find chance (max +10%). • Specialist ship bonus increases specific reward type chance (max +10%). • Exploration Ships increase quantity and quality (max +100%). • Only one specialist ship applies per reward roll. • All categories stack together. • Cargo limits what you can bring back.

Strategy Tip

A balanced expedition fleet often includes:

Probes (to increase chance of discovery)
Exploration Ships (to improve reward quality & amount)
One focused specialist ship (based on desired reward)
Combat ships (to unlock discovery tiers)
Sufficient cargo ships

Building fleets with a clear objective will consistently outperform random compositions.
