The Ominous Bottle (III) grants the Bad Omen III effect for 100 minutes (1:40:00) when consumed. This item is a rare drop from raid captains outside of raids and corresponds to a higher difficulty level for events triggered by the effect. With Bad Omen III, entering a village initiates a raid with even stronger waves and tougher enemies, providing greater challenges and rewards. If near a non-ominous trial spawner, the effect transforms into Trial Omen III, activating a more difficult custom event. This bottle is a powerful tool for players seeking to engage in high-level raid combat or advanced custom gameplay scenarios.
