Throws axes that pass through enemies, damaging every enemy along the flight path. A single axe piercing a dense line of enemies hits each one, making Bullova highly efficient against enemies aligned in the projectile's path. Additionally, specific movement inputs can trigger the "Hell's Fury" technique — a special attack pattern beyond the standard throw.

Unlocked by finding Bullova and fully evolving it (an exploration-based unlock that requires locating the weapon in a stage and completing its evolution). Evolution requires Skull O'Maniac — an item that buffs all enemies on screen (+10% to speed, HP, count, and attack frequency). The enemy buff is active while Skull O'Maniac is held, so fast-tracking to evolution minimizes the penalty period.

Max Bullova (Lv 8), carry Skull O'Maniac (enemy-buffing item), and open an elite-drop chest after 10:00 to evolve into Falconwind.

Falconwind Effect

After evolution adds the "Reverse Delta" technique — a more advanced special attack pattern on top of the Hell's Fury available pre-evolution. The expanded technique set broadens the weapon's attack flexibility significantly.

• Piercing attack damages every enemy in the axe's path — strong against lined-up clusters
• Hell's Fury technique unlocks a powerful non-standard attack pattern
• Post-evolution Reverse Delta adds another high-level technique
• Piercing nature is consistently efficient in high-density enemy corridors

• Skull O'Maniac buffs all enemies while held — holding it too long makes the run substantially harder
• The longer Skull O'Maniac is carried before evolution, the stronger enemies become
• Special techniques (Hell's Fury, Reverse Delta) require learning specific input patterns
• Piercing advantage is reduced against scattered enemies not aligned with the throw path

• Characters with movement speed bonuses: faster movement improves ability to align throws through enemy clusters
• Imelda: +10% Growth reaches max level faster, reducing the Skull O'Maniac penalty window
• Gennaro: extra projectile count puts more axes on screen simultaneously

• Skull O'Maniac: mandatory for evolution — evolve as fast as possible to minimize the enemy-buff period
• Spinach: +10% Might raises piercing damage (top priority)
• Candelabrador: wider area extends axe flight distance and hit radius
• Duplicator: extra projectile count increases simultaneous axe count

• IX Divine Bloodline: crit compounding on multi-enemy piercing hits
• IV Soul Eater: movement speed bonus enables precise positioning to thread axes through enemy lines

• Early (0–10 min): Level Bullova and secure Spinach early. Focus movement to align throws through the densest enemy lines — every additional enemy the axe pierces multiplies its value.
• Mid (10–20 min): Acquire Skull O'Maniac and immediately push to max level — hit Lv MAX and open a chest as quickly as possible to convert to Falconwind before the enemy buffs compound further.
• Late (20+ min): Falconwind's Reverse Delta expands the technique set. Practice the input patterns for both Hell's Fury and Reverse Delta to access the full attack repertoire.

Q: How do I unlock Bullova?
A: Find Bullova in a stage and fully evolve it. It's an exploration unlock — the weapon must be discovered within a run rather than selected from a standard level-up menu.

Q: What does Skull O'Maniac do while I hold it?
A: All enemies gain +10% to speed, HP, count, and attack frequency for as long as it's in your inventory. Reach Bullova's max level and evolve it as fast as possible — every extra minute with Skull O'Maniac makes the run harder.

Q: How do I activate Hell's Fury and Reverse Delta?
A: Both are triggered by specific movement patterns or input sequences — hidden techniques within the game. Learning the exact activation conditions significantly broadens the weapon's attack flexibility.
