After leaving Farebury and traversing the plains, you'll eventually reach the town of Alexandria. Upon entering, you'll learn about the mysterious disappearance of Jessica Albert, a powerful mage. Your path will lead you to the towering structure overlooking the town: the Tower of Alexandria. This is your first proper dungeon, so be prepared for more challenging enemies and puzzles.
The Tower of Alexandria is a multi-floor dungeon with several treasure chests containing valuable items like Medicinal Herbs, Antidotal Herbs, and even some early equipment upgrades. The enemies here include Drackies, Slimes, and the new Firespirits and She-Slimes. Firespirits are weak to ice spells (which you won't have yet, but keep in mind for later), and She-Slimes can call for backup. Navigate the tower by finding staircases and occasionally pushing blocks to open new paths. Your ultimate goal is to reach the top where Jessica is rumored to be. save at the church in Alexandria before entering the tower.
