Schools of Magic, now in 1.16.5, adds Dnd style of magic to Minecraft. Cast spell of various elemental types in the Schools of Abjuration, Evocation, Illusion, Divination, Transfiguration, and Conjuration. All you need to get started is the Basic Arcana (which you can get from beating another spell caster like a Witch, Evoker, or Illusioner), an Apprentice Wand, and a podium to put your spellbook on.
The tea brewing system provides an early game method of getting potion effects, however getting the exact effects you want can take some planning and experimentation.
This mod is a port from 1.12.2, and I plan on adding a lot of the content featured in that mod. Hopefully even better, with the benefit of hindsight. Features like the advanced brewing system, the teas, the custom potion effects, the customizable wands and grimoires, the biomes, dungeons, plants, crops, and creatures, and all the spells.
