A DLC weapon that fires a single arrow in a straight line in the direction the character is facing. It carries a native critical damage chance — critical hits can occur independently of Luck stat values.

The defining mechanic is Amount stat inversion: most weapons use Amount to increase how many projectiles fire simultaneously, but Flash Arrow converts Amount into a damage multiplier instead. Raising Amount via Duplicator or arcanas does not add more arrows — it increases the damage of each arrow fired. This distinction fundamentally shapes how the weapon should be built.

Unlocked by surviving 15 minutes with Kiisa Muort (DLC character). Bracer as the evolution material raises movement speed — improving the mobility used to change the arrow's firing direction in combat.

Max Flash Arrow (Lv 8), carry Bracer, and open an elite-drop chest after 10:00 to evolve. The post-evolution weapon name is currently unconfirmed.

• Amount converts to damage multiplier: each point of Amount raises per-arrow damage rather than adding arrows, making Amount increases disproportionately effective for single-hit damage output
• Native critical hit chance produces burst spikes independent of Luck investment
• Straight-line trajectory delivers full concentrated damage to any enemy in the direct line of fire
• Bracer's speed increase improves mobility for rapid direction changes in combat

• Requires DLC for Kiisa Muort
• 15-minute survival with Kiisa Muort is a heavy unlock requirement
• Amount does not add projectile count — multi-hit spread benefits are not available
• Straight-line only — enemies approaching from the sides or behind are not covered
• Evolution destination currently unknown

• Kiisa Muort: the DLC unlock character; other characters can use it effectively after unlocking
• High-Might characters: Might multiplies with Amount's damage multiplier for compounding per-arrow damage
• High-movement-speed characters: combined with Bracer for rapid direction-change combat

• Bracer: mandatory for evolution; speed increase improves directional flexibility (top priority)
• Duplicator: Amount increase converts directly to per-arrow damage multiplier — the highest-leverage stat increase available for Flash Arrow
• Spinach: +10% Might; multiplies with Amount's damage modifier for compounding single-arrow burst damage
• Clover: Luck increase raises native critical hit frequency, boosting DPS

• IX Divine Bloodline: crit compounding on the native critical chance produces very high burst spikes per arrow
• XIV Jail of Crystal: additional straight-line hits complement the facing-direction firing pattern

• Early (0–10 min): Level Flash Arrow and secure Bracer early for both evolution and speed. Pick up Duplicator immediately if found — Amount's damage multiplier effect is larger here than on most other weapons because it raises per-arrow damage rather than spreading shots.
• Mid (10–20 min): Carry Bracer and push to Lv8 for evolution. Stack Spinach and Duplicator: Spinach's Might bonus multiplies with Amount's damage modifier, creating compounding growth in single-arrow burst damage.
• Late (20+ min): With high Amount as a damage multiplier and Spinach stacked, each arrow's individual damage is very high. Clover and Divine Bloodline convert the native crit chance into frequent extremely high burst hits.

Q: How do I unlock Flash Arrow?
A: Survive 15 minutes with Kiisa Muort. Owning the required DLC is necessary.

Q: Why doesn't raising Amount add more arrows?
A: Flash Arrow's Amount stat is inverted — it functions as a damage multiplier for each arrow rather than increasing simultaneous projectile count. This is a Flash Arrow-specific mechanic distinct from most other weapons, and it means Duplicator provides a larger per-use damage increase here than on conventional projectile weapons.

Q: What does the native critical chance mean?
A: Flash Arrow has a built-in crit probability that fires independently of the Luck stat. Even without Clover or luck-boosting arcanas, crits occur regularly. Combined with high Amount as a damage multiplier, each crit produces a very large burst spike per arrow.
