Viscous is a disruptive tank support in Deadlock who leverages Goo-based crowd control to protect allies and harass enemies. Puddle Punch and The Cube create unique repositioning and denial tools that frustrate enemy engagements. Best builds stack Vitality for maximum tankiness and Spirit Power to amplify Goo ability effectiveness. Viscous excels in coordinated compositions where The Cube can counter key enemy ultimates. He is less effective in solo queue where teammates may not understand or follow up on his unusual crowd control windows. A niche meta pick who provides exceptional value in organized team play.
