You can get a basic understanding of item crafting by using the in-game Guidebook. From there, you'll learn how to craft Essences and other ingredients to conjure magical items. The crafting system may seem intimidating and complex at first, but it becomes easier as you start making basic ingredients. Build a Mana Generator, use it to create auras, and transform them into essences.
Magic scrolls are powerful spell carriers in this addon. By using them, you can summon meteors from the sky to unleash destruction on mobs and bosses you'll inevitably face. The most fearsome of them is Cthulhu, a dark deity that deprives you of sanity just by looking at it.
