It's a mod pack that adds many new biomes and bosses to defeat. Through exploration, you'll find artifacts that will help you in battle, while others you can use to craft increasingly powerful armor. Furthermore, the mod pack also includes a mod that uses your mana to create spells, and by upgrading your spellbook, you'll gain increasingly powerful spells to use against bosses. I warn you, the bosses are very complex, and netherite armor can be a huge help. If you also use spells from the level 3 spellbook, it would be even better.
For the magic mod, which is very complex to understand, I'll leave you a link so you can study it better and fully use the power of magic.
