Unique artifacts are equipment pieces that grant immense power to their bearer. Their effects are diverse and distinct, as they were crafted specifically for their wielder. Currently, there are 4 unique artifacts in existence:

Salonox's Ring of the Divine Mind

An artifact as ancient as time itself, said to have been forged in the breath of creation by Salonox, the god of boundless thought. Lost across the veils of countless realities, it calls only to those whose fate is written in the stars. The one who bears it is whispered to wield a mind vast as the cosmos, able to unravel the fabric of existence and peer beyond the limits of mortal comprehension.

Ring of the Shadow Monarch

Forged in the depths where light perishes, this ring holds the essence of the shadow god Noctharon. Its bearer gains the right to command the battlefield with absolute authority—bending time, ruling over souls, and mastering death itself. When night falls, the ring reveals its true form, and even the darkness bows before its king.

Apply: Authority of the Ruler: grants bonus XP and gold based on how quickly an enemy is defeated, with a maximum of 5x gold and 2x XP if the enemy is defeated by the end of the second turn; on the third turn the bonus is reduced, and from the fourth turn onward the skill is replaced by Monarch's Dominion.
At night, the turn limit for Authority of the Ruler is removed, allowing the bonuses to remain active throughout the entire battle.
Shadow Absorption: a passive effect that gives a 20% chance of extra rewards upon completing missions, including bonus XP, gold, and an additional item; this chance increases to 50% at night, with a higher likelihood of rare items.
Monarch's Dominion: activates on the fourth turn during the day, or from the start of battle at night, granting 1 authority point per turn up to 10; each point provides +10% damage and +20% defense, with partial resistance to negative effects starting at level 6.
At night, Monarch's Dominion points accumulate from the first turn and can coexist with Authority of the Ruler bonuses, making the user extremely powerful.

Sickle of Crimson Reckoning

Forged by Karynthia, the Forgotten Goddess of Blood Debts, this cursed scythe doesn't steal life, it binds it. Each wound it inflicts chains the victim to an invisible contract with fate, where survival itself becomes a currency that must be endlessly repaid.

Apply: Crimson Life Bond: every hit binds a Life Contract to you, up to 200% of max HP. It blocks all direct healing, but grants scaling damage and bonus damage per hit while active.
Art of Judgement: attacks build up Crimson Debt on the enemy; at 100% debt the target suffers a massive burst of damage, part of which is converted into more Life Contract. If the enemy is defeated while indebted, the remaining debt is absorbed as healing.
Mask of Crimson Death: while the Life Contract is active, +60% elemental damage, +40% action speed, and 30% of the enemy's defense is ignored.
Crimson Execution: once every 3 turns, consume the entire Life Contract to deal massive defense-ignoring damage and heal yourself proportionally to the debt consumed. The only source of direct healing.
Accumulated Sin: every 25% of Life Contract grants +10% damage, +5% double attack chance and +5% universal defense, up to +80% damage, +40% double attack chance and +40% defense at 200%.
Presence of the Fatui: at the start of battle, gain 50% Life Contract and inflict initial Crimson Debt on the enemy.
