Noted that the equipment screen now lists which Spirit Stone effects are active
11Spirit Stone Categories are the effect families that Spirit Stones are organised into in Beast of Reincarnation. Each stone belongs to one of five categories, and players slot stones from across the categories into Emma's armour to compose a parry-driven build.2233The Five Categories4455Every stone carries exactly one stat boost, drawn from the list below, alongside its own individual effect. The stat boost is what the categories name; the effect is what actually separates two stones in the same category. A handful of stones raise maximum FP instead, which sits outside the five.6677CategoryEffect FocusBuild DirectionHPMaximum health, healing on trigger, and survival cushion.Sustain builds that lean on long fights rather than fast resolutions.AttackRaw outgoing damage, particularly on the parry-driven punish window.Damage-forward builds that convert each parry into a meaningful chunk of HP off the enemy.DefenseIncoming damage mitigation and resilience against the harder hits in late-arc encounters.Tank-leaning builds that turn parries into safety windows rather than damage spikes.Skill PowerImproves the strength of Emma's combat skills and the impact of Bloom Arts fired through Koo's Command System.Hybrid builds that use the parry rhythm to amplify both sword work and Koo's plant abilities at once.Critical RateHigher chance for outgoing strikes to land as critical hits.Burst builds that stack parries into a damage-spike window, often paired with faster katanas.88Slot Economy991010Spirit Stones are slotted into armour rather than into the katana. The number of available slots scales with the armour piece.11111212Standard armour. Slot counts belong to the armor set, not to a tier. Each of the fourteen sets carries its own number, listed alongside its defense and elemental resistance.Upgraded armour. Up to six Spirit Stone slots, available through later-arc upgrades.13131414Slot count is the practical cap on how many categories a build can lean on at once. A four-slot loadout is forced to specialise; a six-slot loadout can hold a primary category plus two or three supporting categories without diluting the primary effect.15151616Effect Triggers17171818The more useful way to sort the catalogue is by what sets a stone off, because that is what has to line up with a build. Parry is one trigger among many rather than the universal one.19192020TriggerExamplesWhat FiresStart of battleFortification, Onslaught, Entanglement StoneOpens the fight with a Fortitude or Vigor buff, or with the Entanglement Gauge and Koo's FP already part-filledParry, dodge, riposteEntangled Parry, Entangled Dodge, Entangled RiposteA percentage chance to return 0.2 of the Entanglement Gauge and a point of FPExecution or assassinationEntangled Assassination, Final Infusion, Final BreathReturns gauge and FP, or a slice of Emma's maximum HPKilling anythingEntangled ConquestReturns gauge and FP on any combat killLow healthWell of Fortitude, Well of Vigor, Mortal Awakening, Double-Edged SwordTrades safety for output, or hands back defense once Emma drops below halfRanged workSharpshooter, Homing Shots, Empowered Headshots, Faster Reloads, Fire RateAdds tracking, headshot damage, reload speed or crossbow fire rateStatus deathsLast Lightning, Infernal EndShocked or burning enemies discharge on death, hitting everything within several metresBloom ArtsFlorescent Recovery, Transcendent BloomHeals over time on activation, or adds damage and stagger while Koo's bar is fullStanding conditionsMomentum, Dark Approach, Critical Mind, Stone Mind, Iron WallPassive multipliers that apply while Emma is at full health, unseen, healing, or simply always21-Stones level up, and most of them scale in five ranks, so the same stone is a different proposition at rank 1 and rank 5.

Upgraded Blighted variants of stones also exist with higher numbers than the base version. Since the August 24 patch the equipment screen lists which Spirit Stone effects are currently active, so a loadout that leans on two or three categories at once can be checked directly rather than inferred from the stone names.22222323Category Pairings24242525PairingIdentityAttack + Critical RateBurst aggressor.

High-tier stones drop from elite enemies, which is why the Chapter 8 experience farm doubles as a stone farm. They can also be duplicated at the Cleanse Walker workbench once enough electronic brains have been collected to raise the Calculations research. Acquisition runs as a parallel discovery loop to Charms and Katanas, with each system rewarding off-path investigation rather than purchase or craft.29293030Counting the Catalogue31313232Both of the independent guide catalogues list around thirty-five named stones, and their rosters differ slightly at the margins, so no exact total is stated here. The category structure and the trigger groupings above hold regardless of where the final count lands.
