Character and Weapon Enhancement Material
A fossilized bone fragment sometimes found after defeating Geovishaps. Geovishaps all dream of growing into great dragons one day. They see these fossils as dragon bones and greatly cherish them, perhaps because they too hope to attain the dragons' longevity and power.
Used by the supported upgrade goals listed below. Requirements depend on the selected current and target levels.
Catalyst★★★★Ballad of the Boundless Blue is a 4-star Catalyst with Energy Recharge as its secondary stat. Normal or Charged Attack hits grant bonuses to both Normal and Charged Attack damage for six seconds, stacking up to three times.
Polearm★★★Black Tassel is a 3-star polearm whose main practical distinction is its HP secondary stat. Its passive increases damage against slimes, so consider it when HP is useful to the wielder or when fighting slimes; the enemy-specific bonus should not be mistaken for a general damage increase.
Bow★★★★Compound Bow is a four-star bow with Physical DMG Bonus as its secondary stat. Normal and Charged Attack hits build temporary ATK and Normal ATK SPD stacks, making it most relevant to a bow user who deals sustained physical Normal Attack damage. Consider its attack-speed benefit separately from the physical stat: the passive does not grant physical damage directly.
Sword★★★★Iron Sting is a 4-star sword with Elemental Mastery and a damage bonus triggered by dealing Elemental DMG. The bonus lasts 6 seconds, stacks twice, and can trigger once per second. Consider it when the wielder deals Elemental DMG and can benefit from both its secondary stat and the all-damage bonus.
Bow★★★★Jade Vista is a four-star Bow with CRIT Rate as its secondary stat. Its passive counts the other party members by elemental type: matching-element members grant the wielder Elemental Mastery, while different-element members grant ATK. Consider it when the wielder can use those stats and the party composition reliably supplies useful stacks.
Polearm★★★★Lithic Spear is a 4-star polearm with an ATK secondary stat. Its passive rewards a Liyue-heavy party: each Liyue character in the party grants the wielder ATK and CRIT Rate, up to four stacks. Consider it when your party composition already meets that condition and the wielder benefits from both stats.
Claymore★★★★Luxurious Sea-Lord is a 4-star claymore with ATK and a passive that boosts Elemental Burst damage. A Burst hit also summons an area-damage tuna effect, once every 15 seconds. Consider it for an ATK-scaling claymore user whose Burst hits opponents and contributes meaningfully to damage.
Catalyst★★★★Mappa Mare is a 4-star catalyst with Elemental Mastery and a stackable Elemental DMG Bonus that activates when an Elemental Reaction is triggered. It suits an elemental damage dealer who can trigger reactions often enough to use its timed stacks.
Catalyst★★★★★Memory of Dust is a 5-star catalyst with ATK and a passive that builds ATK through hits, while increasing Shield Strength. Its ATK effect is doubled while the wielder is protected by a shield. Consider it for an ATK-focused catalyst user when shield uptime is available and the character can land repeated hits.
Claymore★★★★Prototype Archaic is a four-star claymore with ATK as its secondary stat. A hit from a Normal or Charged Attack has a chance to trigger additional ATK-based damage in a small area, subject to a 15-second limit.
Polearm★★★★Prototype Starglitter pairs Energy Recharge with a bonus to Normal and Charged Attack DMG after the wielder uses an Elemental Skill. Its passive is limited to those attack types and lasts 12 seconds.
Claymore★★★★Serpent Spine is a four-star claymore with CRIT Rate and a stacking damage bonus that also increases damage taken. Consider it for an on-field wielder who can build stacks before fighting and avoid being hit, since taking damage removes a stack.
Sword★★★★Silver Light is a four-star sword with ATK and an Elemental Mastery buff after Elemental Skill use. Consider it for a wielder who can use Elemental Mastery and whose Skill cadence lets them gain up to two independently timed stacks.
Claymore★★★Skyrider Greatsword is a three-star claymore with Physical DMG Bonus and a stacking ATK increase on Normal or Charged Attack hits. Consider it for an on-field user who attacks repeatedly and can maintain the short stack duration.
Sword★★★Skyrider Sword is a three-star sword with Energy Recharge as its secondary stat. Using an Elemental Burst grants a temporary ATK and Movement SPD increase.
Polearm★★★★★Vortex Vanquisher combines ATK scaling with a shield-oriented passive. Consider it for a polearm wielder who lands repeated hits and stays protected by a shield; its attack bonus doubles while shielded.
