Acro's Classical Elements is an Electroblob's Wizardry inspired mod with over 100 spells.

note: 1.18.1 has a specific version you will need to use, the latest 1.18.2 release will not work!

You find spells in buried chests, stronghold libraries, deserts and jungle temples, and can also get it from a cleric as a reward with Hero Of The Village

to use a spell, you hold the spellbook in your offhand and then right click it, you can then unequip the book as it is now on your wand.

You scroll through spells with the scroll wheel whilst holding the wand

you obtain "wands" in the same places as the books, there is a normal wand that uses mana plus a few others:

Wand: 20 mana, 5 max spells, mana regen speed 1

Casting orb: 30 mana, 5 max spells, mana regen 2

Demon Katar: 5 max spells, but costs health equal to mana cost to cast

Grimoire: costs no mana, but all 5 spells are randomised and cannot be changed

in 1.17 there are no evil mages, in all other versions, there are.
