Vyper is an aggressive melee brawler in Deadlock who applies persistent poison damage to wear down enemies in sustained fights. Serpent Skin and Venom Spray reward staying in melee range and repeatedly applying stacks for escalating damage. Best builds stack Weapon damage and Vitality for effective close-range fighting alongside venom amplification. Vyper excels in 1v1 brawls and against tanky heroes who take multiple hits to burst but succumb to venom stacks. She struggles against burst assassins who can eliminate her before venom builds up. A consistent meta fighter for players who enjoy disciplined close-range combat.
