How to play

Viscous is a disruptive support. The Cube encases an ally (or himself) in invulnerable goo, Splatter leaves slowing puddles, Puddle Punch summons a fist from 40 metres away, and Goo Ball turns him into a bouncing, stunning ball of slime.

Laning phase (0–10 min)

• Splatter for trades and slows. Bounce it into the enemy hero.
• Puddle Punch from range. It knocks up and slows; beware, enemies can parry it.
• Your alt-fire deals 42 damage for 5 ammo, which is good for poking.

Mid game (10–25 min)

• Save allies with The Cube. Make a focused teammate invulnerable while your team responds.
• Cube yourself to escape burst or reset a fight.

Late game and team fights (25+ min)

• Goo Ball to engage. Roll through the enemy team, stunning everyone you hit.
• Goo Ball forces Urn carriers to drop the urn, which is great for stopping urn runs.
• Cube T3 removes debuffs, which saves allies from crowd control.

Combos

1. Engage: Goo Ball into the enemy team → Splatter on the stunned group → Puddle Punch.
2. Save: The Cube on the focused ally → Splatter to slow the divers.
3. Pick: Puddle Punch (knock-up) → Splatter → shoot.

Matchups

• Good against: burst teams (The Cube wastes their damage) and urn carriers.
• Hard against: teams that wait out the Cube and anyone who parries Puddle Punch.

Pro tips

• Allies slide faster on your puddles, which helps them rotate and escape.
• Puddle Punch T3 deals heavy melee damage, so it scales with melee items.

Lore

Viscous is a psychic sea anemone from the depths of the Bermuda Triangle. He's taken on a body made of goo to summon the Patrons and protect his home from a dark predator known as the Adversary.
