🏹 Ender Bow

📦 Obtaining

Option 1 - Crafting table:

Option 2 - Drop Crafting:

Drop the following items on the ground:

• 1 Bow
• 4 Ender Pearls

The Ender Bow recipe will also automatically unlock when you obtain the required materials.

🎯 Usage

• Hold right-click, just like a normal bow.
• You'll follow the arrow until it lands.

🚀 Jet Packs

The Jet Pack comes in five tiers, each providing increased fuel capacity, speed, and maximum altitude.

Each tier also has its own custom color, making it easy to distinguish between them.

💡 The altitude limit is measured as the height above the ground directly below the player(*). Once the maximum altitude is reached, the Jet Pack will no longer provide upward thrust and you will hover around the max altitude.

*Leaves are not counted as ground.

Give:

🕹️ Usage

• Equip the Jet Pack in your chestplate slot.
• Sneak to activate it.
• Stop sneaking to descend with Slow Falling.

Tip: if Slow Falling is too slow for you, consider switching to your normal chestplate to descend faster and switch back just before hitting the ground (-> no fall damage, but normal fall speed!)

👤 Morph System

⚠️ Experimental: The Morph System is still experimental and may not work perfectly with every mob (especially big mobs like the Iron Golem).

🪄 Morph into a Mob

Replace <MobName> with the name of the mob you want to morph into.

🔙 Unmorph

👻 Ghost Blocks

Ghost Blocks appear as normal blocks, but you can phase through them.

📦 Obtaining

Replace <BlockName> with the block you want to get the Ghost Block spawn egg for.

🧱 Usage

Just spawn it wherever you want

🗑️ Removal

Remove one Ghost Block (the nearest one):

Remove all Ghost Blocks in a 10×10×10 area:

Remove all Ghost Blocks in the world(*):

*In all the loaded chunks of the world

⚙️ Utility Functions

Cool Functions also provides various utility functions that can be accessed directly through Minecraft's /function command.

🧹 ClearLag

ClearLag allows you to manually remove dropped items from the world. This can help performance when there's a lot of items on the ground.

🗑️ Clear All Ground Items

This removes dropped item entities from the world(*).
