Billy is an explosive trapper in Deadlock who controls areas with bombs and persistent damage fields. Bomb Throw and his detonation kit reward careful trap placement and area denial more than direct combat. Best builds invest in Spirit Power to amplify bomb damage and cooldown reduction for sustained trap placement uptime. Billy excels on defense and in objective fights where he can pre-plant traps before enemies arrive. He can struggle in aggressive skirmishing compositions where reactive trap usage is less reliable than proactive placement. A high-skill-ceiling pick who rewards strategic positioning and preparation over mechanical dueling ability.
