Billy
Billy is a solid, accessible Physical attacker who excels at mid-to-long-range sustained damage. He is a great investment for new players needing a reliable main DPS before pulling for high-tier limited units.
Billy acts as a precise physical damage dealer, utilizing his unique Crouching Shot mechanic to sustain high-output pierce damage from distance. His toolkit relies on positioning and timing, as he can transition into Rolling Shots to reposition while maintaining his onslaught. He gains significant damage buffs through his Core Passive when remaining stationary, encouraging players to master the balance between aggressive firing and strategic movement.
