Splashers is a Duration-scaling weapon obtained through the weapon evolution line. Damage output scales with the Duration stat — higher Duration means higher damage per hit. It also has the ability to glimmer the "Dual Whirlwind" tech, which triggers an additional whirlwind attack when the glimmer condition is met. Forbidden Tome (封魔の書) is the evolution material.

• Damage scales with the Duration stat — more Duration means more damage per activation
• Higher Duration produces proportionally higher attack output
• Can glimmer the "Dual Whirlwind" tech — additional whirlwind-type attacks fire when the glimmer triggers
• Glimmer activation expands the effective damage coverage with a second rotational strike
• Forbidden Tome (封魔の書) is the paired passive and evolution material

Hold Forbidden Tome, level Splashers to MAX, then open a treasure chest after 10:00 (evolved form name to be confirmed).

Forbidden Tome is a Duration-related passive that also raises the weapon's scaling source while held as the evolution material — securing it serves both purposes simultaneously.

• Duration scaling makes Spellbinder the primary damage passive — a direct investment with no stat conversion
• Dual Whirlwind glimmer adds supplemental area coverage when triggered, rewarding dense enemy engagement
• Duration investment simultaneously extends effect durations across the full loadout
• Forbidden Tome raises Duration while serving as the evolution material — no opportunity cost for holding it

• Obtained via the weapon evolution line — exact acquisition timing depends on run progression
• Low-Duration builds see weak damage scaling; the weapon underperforms without Duration investment
• Dual Whirlwind glimmer trigger conditions and probability are not fully confirmed — glimmer consistency is uncertain
• Evolved form details are unconfirmed — late-game build planning has some uncertainty

Characters with naturally high Duration bonuses or builds oriented around Duration investment fit best. The Dual Whirlwind glimmer suggests spin and rotational attack styles are the natural complement — builds that stay inside enemy clusters to maximize the additional whirlwind coverage benefit most.

Build priority is Duration: secure Spellbinder and Forbidden Tome early. Each point of Duration directly multiplies per-hit damage — the weapon's full output scales linearly with the Duration total. Forbidden Tome simultaneously satisfies the evolution condition and raises Duration, making it the most efficient first acquisition.

When Dual Whirlwind glimmer activates, position in dense enemy clusters to maximize the additional whirlwind hit. The supplemental rotational strike covers a wider radius — staying inside groups of enemies ensures the bonus coverage hits as many targets as possible.

Area investment expands both the primary attack and the Dual Whirlwind glimmer's coverage zone. Candelabrador complements Duration investment without competing for the same passive priority.

Q. What triggers the Dual Whirlwind glimmer? A. Dual Whirlwind is a glimmer tech — a special state that fires the additional tech when specific in-run conditions are met with Splashers equipped. Exact trigger probability and conditions are not fully confirmed in public sources.

Q. How much Duration should I stack? A. More Duration always means higher damage — there is no diminishing returns cap. Prioritize Spellbinder and continue stacking as long as passive slots allow.

Q. What is Forbidden Tome (封魔の書)? A. Forbidden Tome is a Duration-related passive item that also functions as Splashers' evolution material. Holding it raises Duration and directly contributes to the weapon's damage scaling while simultaneously satisfying the evolution requirement.
