Modes

Normal Mode

• Primary: rapid hitscan slashes (Damage: 4–6 per hit)
• Secondary (charged): piercing wide slash that spawns a multi-hit AoE on impact (Damage: ~170 per hit ×7)
• Slash shapes: Thin & Long (vertical) and Thin & Wide (horizontal)
• Black Flash: small chance to trigger huge damage (×2.5), hitstop and style bonuses; chains between 1–36 extra attacks

Positive Mode

• The cube turns yellow; Black Flash is disabled.
• Damage multiplier (default ×16) and healing on hit (Primary/Secondary configurable).
• Rapid-fire slashes when scrolling the wheel (alternative to switching shapes).
• Reverse Cursed Technique (RCT): in Positive Mode, Middle Mouse instantly heals to 200 HP and spawns a yellow sphere that halves enemies' health periodically while active.

Domain Expansion

• Hold Middle Mouse to charge a Domain; release to deploy a black sphere that follows you.
• Enemies inside take continuous primary and secondary damage; domain duration and radius are configurable.
• Domain ticks have a configurable chance to trigger a Black Flash.
