This is one of the trickier items to find, as it can only be obtained from a specific mob. If you're hoping for the best loot Trial Chambers has to offer, read on to learn how to get and use an Ominous Bottle in Minecraft.
You can obtain an Ominous Bottle in Minecraft by defeating a raider holding an ominous banner, also known as the raider captain. This means you'll need to find a group of roaming raiders outside of a village raid or track down a raider outpost.
Raiders roam in patrol groups of one to five. Their patrol occurs every five and a half days at any time of day, after which the group spawns approximately 28 to 48 blocks away from you. This is usually the easiest way to get an Ominous Bottle, as you only have to deal with a small group of Raiders instead of an entire outpost.
