# Precursor Towers A great tool for exploration are [[Precursor Towers]]. These mysterious precursor constructs are dotted around the Atlas. Completing the tower will reveal a large area around it, allowing you to scout out your next challenge. There are a lot of things to find, so keep looking. Some sections of the Atlas are influenced by corruption. This adds extra modifiers to the maps in the region, increasing the difficulty and rewards. Here, slaying monsters in close proximity to each other will cause vestiges of corruption within them to merge together, forming powerful and grotesque abominations.
