Slots are the real limit on relics
Relics look generous until you meet the slots. Every Nightfarer gets three relic slots, and those slots are colour-coded, so owning a powerful relic is useless if nobody can wear its colour.
Read your slots before you plan a build. Colour availability decides which relics are actually options.
The four colours
Relics come tied to one of four colours, each linked to a scene type. Alongside colour, relics carry a rarity tier that sets how many effects they roll.
When you are choosing between two relics, colour fit comes first. A perfectly rolled relic you cannot equip is worth nothing to that Nightfarer.
Different Nightfarers, different combinations
Each Nightfarer has a different mix of slot colours. That is why two players can hold the same relic pool and build completely different loadouts.
It also means a Nightfarer you rarely use may have exactly the slot colours a relic you want needs.
Planning around limited room
With three slots, each choice costs you something. Decide what role each slot plays: one for damage, one for survivability, one for whatever your team lacks.
Revisit the loadout when your relic pool changes. A build that was best last week can be beaten by a relic you picked up since.
Check before you grind
If you are farming for a specific relic, confirm that the Nightfarer you intend to use can equip its colour first. It is a common waste to collect something unusable.
Fill every colour first
Vessels are colour-coded relic slots. A complete set of on-colour relics beats one off-colour rare, because the set actually triggers your plan.
Check limits before committing
Know your vessel count before you build a run around a relic. Chasing a power you cannot equip wastes the whole expedition.
