Ive always loved the idea of magic in games and seeing as how Minecraft today has use of Fire Aspect for use on other weapons.
My idea as to how this would play out:-
Wands being where you combine 2-3 sticks together to make a "wooden rod" (talking as in sticks are usually like twigs)
Staffs being two "wooden rod" on top of one another to make a "staff rod"
Coming in the form of a book but either they be found in chests or via Enchantment table using the books.
Crafting the two together
Using the crafting table you can then combine to spell/wand/or staff rod to make your magical weapon of use.
Fire Ball (fire ofc)
Tip: those ofc are just random ideas. Dosent have to be lighting or fire.
My idea of seeing this feature is mainly for fitting in with the aspects of brewing, enchantments, and the fact of the already added enchantment (fire aspect) in which magically sets fire to whom you attack.
