With this data pack enabled, you can craft an Annihilation Scroll.

--Crafting--

To craft, throw the following items together on the ground:
1 Nether Star
1 Netherite Block
2 Diamond Block
32 Emerald Block

--Use--

In order to use this weapon, you need to hold a regular stick in your offhand. Then, drop the scroll (it will return to your inventory).
A beam 100 blocks long will be cast out in front of you. Any time it contacts a block or entity along its path, it will cause an explosion.
The scroll has a one second cooldown.
