Calibration Spike
uncommon Flagship Artifact
A precision instrument used to calibrate targeting arrays. Whoever owned this one calibrated it so many times the grip is worn smooth — but the tip remains factory-perfect.
Passive bonuses
- +6% Fleet Accuracy
- +5% Cooldown Reduction Scan
How to get
Craft Reward, Expedition Cache
Worn Navigation Chart
common Flagship Artifact
A paper star chart — an anachronism even when it was made. The margins are covered in handwritten notes about currents, safe stops, and warnings: 'DO NOT go through here in summer.'
Passive bonuses
- +4% Expedition Speed

Salvage, Expedition Cache
Which Artifact Should You Equip?
Calibration Spike is the higher-rarity relic, so it carries the stronger ceiling for the Flagship slot and is the long-term target. That said, if you are already running the No Set set, the set bonus can outweigh raw rarity — favour the artifact that completes a set you already own.
