In Hypixel Skyblock, Blaze Ashes are a valuable crafting material primarily obtained by defeating Blaze mobs in the Blazing Fortress. You can use Blaze Ashes to create Blaze Powder, which is useful for various purposes in the game. Here’s how to get Blaze Ashes:

1. Go to the Blazing Fortress: Blaze mobs spawn in the Blazing Fortress, which is accessible from the Spider’s Den. To reach the Blazing Fortress, you will need to progress through the different zones in Skyblock and unlock the portal to this area.
2. Prepare for Combat: Blaze mobs are hostile and can be challenging to defeat. Ensure you have appropriate gear, weapons, and armor to handle combat in the Blazing Fortress. It’s recommended to have strong weapons and good armor to protect yourself.
3. Hunt for Blaze Mobs: Once you’re in the Blazing Fortress, look for Blaze mobs. They are flying, fire-based creatures that are often found floating around the fortress.
4. Defeat Blaze Mobs: Engage Blaze mobs in combat and defeat them. When you defeat a Blaze, it will drop Blaze Rods and occasionally Blaze Ashes.
5. Collect Blaze Ashes: Collect the Blaze Ashes that drop as loot from defeated Blaze mobs. Blaze Ashes are relatively rare drops, so you may need to defeat several Blaze mobs to gather a significant amount.
6. Use Blaze Powder: You can use Blaze Ashes to craft Blaze Powder at a crafting table. Blaze Powder is a versatile material used in various crafting recipes, including those for brewing potions, enchanting, and more.
7. Repeat as Needed: If you require more Blaze Ashes, continue hunting Blaze mobs in the Blazing Fortress and defeating them to collect additional ashes.

Please keep in mind that the Blazing Fortress can be a challenging area, and it’s essential to be well-prepared before entering. Additionally, the drop rates for Blaze Ashes may vary, so it may take some time and effort to collect a significant quantity.
