The Ominous Bottle (II) grants the Bad Omen II effect for 100 minutes (1:40:00) when consumed. It is a rare drop from raid captains outside of raids. The higher level of the effect increases the difficulty and rewards of the triggered event. When under Bad Omen II, entering a village starts a raid with stronger waves of enemies due to the higher level. Near a non-ominous trial spawner, it transforms into Trial Omen II, triggering a more challenging custom event. This item provides a strategic way to engage with advanced raid mechanics or specialized custom scenarios.
