New Enchanted Book (Firebending)

Firebending would be useful for Flint & Steel.

It'd be compatible with Mending, Unbreaking, and Curse of Vanishing.

The new enchantment would have three levels: I, II, III.

It would allow the player to set multiple blocks on fire at the same time with one use. However, it would take more durability in return.

Level I: Setting 3x3 blocks on fire

Level II: Setting 6x6 blocks on fire 

Level III: Setting 9x9 blocks on fire

Firebending would also allow putting fire on the snow layers and Power Snow Blocks.

The new book could not be acquired through the Enchanting Table. It can be found as a loot in the chest in certain structures with a certain % chance of finding: 

1. Mineshaft 

2. Ocean Ruins

3. Buried Treasure

4. Ruined Portal

5. Shipwreck

6. Villages

12. Igloo

13. Jungle Pyramid

14. Mansion

15. Mineshaft Mesa

16. Pillager Outpost

In each structure, the percentage of finding the enhanced book would differ.
