How to Guarantee Heavy Core?

Heavy Cores are a valuable item in Minecraft, used to craft the powerful Mace weapon. Kill a Pillager Captain (found in Pillager Outposts, Patrols, and Woodland Mansions). 

Here’s how to get them:

1. Start an Ominous Trial:

• Find an Ominous Bottle: Kill a Pillager Captain (found in Pillager Outposts, Patrols, and Woodland Mansions). They have a chance to drop an Ominous Bottle.
• Locate a Trial Chamber: These are underground structures found between Y levels -20 and -40. You can find them by exploring or by buying a Trial Chamber map from a Cartographer villager.
• Drink the Ominous Bottle: Once inside the Trial Chamber, drink the Ominous Bottle to initiate the Ominous Trial. This will trigger waves of powerful enemies.

2. Defeat the Ominous Spawners:

• Fight off waves of mobs: The Trial Chamber will spawn waves of increasingly difficult enemies. Defeat them to progress.
• Obtain the Ominous Vault Key: After defeating enough waves, an Ominous Vault Key will drop.

3. Open the Ominous Vault:

• Find the Ominous Vault: The Ominous Vault is a small structure within the Trial Chamber.
• Insert the Key: Use the Ominous Vault Key on the vault to open it.

4. Claim your loot (hopefully a Heavy Core!):

• Check the Vault’s contents: The vault contains a random selection of valuable loot.
• Heavy Core drop chance: There’s a 7.5% chance for a Heavy Core to be among the loot.

Tips for increasing your chances:

• Repeat Ominous Trials: Since the Heavy Core drop rate is low, you’ll likely need to complete multiple trials.
• Look for visual cues: Some players report seeing the Heavy Core inside the vault before opening it. Try observing the vault from different angles before inserting the key.

Important Notes:

• Heavy Cores were introduced in Minecraft 1.21. Make sure you’re playing on a version that includes this update.
• Ominous Trials can be quite challenging. Make sure you’re well-equipped with strong armor and weapons before attempting one.
