Perception

Perception is a unit category in All Star Tower Defense that groups together a large set of units, including leaders such as Kosuke (SS), Mysterious X variants, Crow (After), Erasure, and Messi (The Egoist). It matters because certain leader abilities specifically boost Perception units: Messi (The Egoist) gives Perception units +15% Attack and +10% Bonus, while Crow (After) gives Perception units +15% Attack.
