Kelvin is a versatile support hero in Deadlock who provides strong utility through movement denial and healing. Arctic Beam and Frost Grenade let him lock down enemies and control space around objectives. Best builds favor Spirit Power for healing and ability damage, paired with Vitality to keep Kelvin alive in extended fights. He excels as a defensive support who can peel for carries while simultaneously threatening pursuing enemies. Kelvin is one of the few heroes with meaningful healing output, making him valuable in attrition-heavy matches. A consistently meta pick who provides reliable teamfight value in most compositions.
