Mo & Krill is an underground ambush bruiser in Deadlock who controls fights with burrowing dives and persistent melee pressure. Burrow and Sand Blast create disorienting engagements where enemies struggle to track the duo's position. Best builds combine Vitality for tankiness with Weapon items to punish enemies caught in the Burrow gap-close. Mo & Krill excel in flanking scenarios and against squishy backline targets who cannot survive the initial dive. He struggles against heroes with strong vertical mobility or reveal abilities. A strong meta frontliner for aggressive players who enjoy unpredictable engagement angles.
