More magic that isn't too far stretched
A new way of telportation would be possible as with other spells, here's how. It would be done on a new block (spell maker?) And would allow you to choose whatever spell you want within xp limit much like the enchanting table and anvil, you take a book(credit for the book given to me by a friends idea) and place it in the slot and put lapis lazuli and whatever item is also required for that, such as the higher the spell is the more xp and the higher the item tier is. The spells would follow under these categories...
Damage would contain any type of damaging potion but on a higher scale and would also have a fire ball similar to a ghasts fireball, something similar to a wither skull, and a knockback using similar mechanics to the combat updates sweeping edge attack that knocks everything in front of you away and the vindicators summoning attack using its spell against whatever you want, even the vindicators.
Health would be any potion that helps you defend yourself and heal you on a better degree, also a ring of healing to heal any friendly mobs like pets and villagers, bane of the undead to harm undead variants on a greatter area attack hitting more at once, and a effect similar to golden apples giving you 4 extra hearts.
Defense would include potions on a gbetter scale such as leaping and swiftness, it would also make a shield usable once that absorbs all damage and doubles it back to its attacker like thorns, adds another armour point for a limited time, and creates a ward tonprotect villages for a certain amount of nights.
Misc would include any other potion that isnt listed in the other catogories as a better version of their potion counterparts, it also allows you to have something similar to vein miner for a short while or a swiftness in mining, being a giants size allowing for greater attacks but slower movement, speed and jump boost for elytra allowing for better take off and flight, constructing a bridge of ive to traverse ovross gaps better, and elemental control to allow for more attacks and better control of your environment, plus a new spell for controlled teleportation.
It would bring a new item called a sceptre or staff that allows better use of theae spells and can be crafted with two blaze rods in line goingbup with a diamond for highest tier and iron for lowest tier and depending on tier staff will depend on how good the spell will be and a new off hand object called "The Magicians orb" it allows for more uses out of spells and can be dropped by vindicators or traded.
