Playing Billy against Viscous

What should I do right now?

Matchup overview

• Their structural weakness: Currently underperforming (around 47-48% win rate on current-patch samples) Why this is shown: Viscous's weaknesses. Strong evidence
• Their structural weakness: Nerfed across the board in the 09-16-2026 patch: Cube range 26m to 20m, Puddle Punch 21s to 24s, alt-fire damage growth -10% Why this is shown: Viscous's weaknesses. Strong evidence
• Their structural weakness: Very low personal damage output — he needs a team to convert his setups Why this is shown: Viscous's weaknesses. Strong evidence
• Neither of you deletes the other, so this matchup is decided by multipliers rather than damage. Resists stack multiplicatively, which means your fourth resist item buys much less percentage than your first; shred is subtracted from the total afterward, which means it is worth more the tankier they get; and healing reduction stacks multiplicatively too, so a second anti-heal source on top of a first is worth far less than the first. The efficient build against Viscous is one anti-heal, one shred, and damage after that. Why this is shown: Resists and healing reduction both stack multiplicatively; shred is subtracted from total resist after multiplication. Strong evidence

What they do against you

• The Cube makes your committed burst vanish — an Assassinate, Ira Domini blessed stake, Telekinesis slam or Petrifying Bola aimed at a cubed ally deals literally nothing, and they come out healed Why this is shown: Authored from Viscous's kit. Strong evidence
• Puddle Punch reaches 40m and knocks you up, cancelling Assassinate's scope, Warden's Last Stand charge, Yamato's Power Slash, or any channel you are committed to Why this is shown: Authored from Viscous's kit. Strong evidence
• Splatter puddles sit on the ground for 10 seconds applying a 28% slow, which is what makes his knockup and his team's follow-up land on a target that thought it was leaving Why this is shown: Authored from Viscous's kit. Strong evidence
• Goo Ball chain-stuns a clumped team for 0.5-0.8s per impact across 11-18 seconds, while he takes 35-55% less damage from everything Why this is shown: Authored from Viscous's kit. Strong evidence
• With Cube T3 he cleanses all non-ultimate debuffs off an ally — your anti-heal, Vyper dagger stacks, Crow bleed and slows all disappear in one cast Why this is shown: Authored from Viscous's kit. Strong evidence

How you counter them

• Bait The Cube out on a target you were going to pressure anyway, then commit your real burst during the 22-42s it is down Why this is shown: Authored counterplay against Viscous. Strong evidence
• Attack from beyond 20m of Viscous himself — since the 09-16-2026 range nerf, a target further than that from him cannot be cubed Why this is shown: Authored counterplay against Viscous. Strong evidence
• Spread your formation so Goo Ball can only hit one person per bounce, and fight in open ground where wall bounces do not exist Why this is shown: Authored counterplay against Viscous. Strong evidence
• Save a hard CC (Warden's Binding Word, Vindicta's Stake, Vyper's Petrifying Bola, Wraith's Telekinesis) specifically for the Goo Ball roll rather than spending it early Why this is shown: Authored counterplay against Viscous. Strong evidence
• Do not fight inside his Splatter puddles; route around them, because the 28% slow is the setup for everything else he does Why this is shown: Authored counterplay against Viscous. Strong evidence
• Viscous contributes through abilities, which makes a hard silence worth more against them than any amount of resist. Focus Lens is the sharpest version: 4.5 seconds of single-target silence at 20m, plus 30% of all damage dealt during the window applied when it expires, on a 45-second cooldown. Against a caster that is not a defensive purchase — it deletes their entire fight participation and then charges them for it. Why this is shown: Focus Lens: 4.5s silence, 20m cast range, 30% of damage dealt applied on expiry, 45s cooldown. Strong evidence

Trading

• While Goo Ball is active he cannot cast The Cube, Splatter or Puddle Punch — that is the window to delete his carry, not to chase the ball Why this is shown: Viscous's vulnerability windows. Strong evidence
• The 22-42s after The Cube is spent: his team has no save and his own escape is gone Why this is shown: Viscous's vulnerability windows. Strong evidence
• After Puddle Punch's single base charge is used (24s cooldown post-09-16-2026), any channelled ability is safe Why this is shown: Viscous's vulnerability windows. Strong evidence
• In open terrain with no walls, Goo Ball's trajectory is predictable and largely dodgeable Why this is shown: Viscous's vulnerability windows. Strong evidence
• His slow projectile weapon means constant lateral strafing at range makes him miss most of his own chip damage Why this is shown: Viscous's vulnerability windows. Strong evidence
• Being stunned by Viscous now pauses your reload rather than restarting it, as of 09-16-2026. That quietly changes when it is safe to reload in this matchup: a reload caught by their stun resumes where it left off instead of costing you the whole cycle, so the old rule of never reloading inside their engagement range is too conservative now. The compensating change is that parrying also pauses your reload, so a defensive parry no longer buys you free reload time. Why this is shown: 09-16-2026: being stunned pauses reload instead of restarting it; parrying also pauses reload. Verified

Laning

• What they want in lane: Splatter's bounces and puddles clear minion waves and hold a lane choke without him needing to step forward Why this is shown: Viscous's laning strengths. Strong evidence
• What they want in lane: The Cube on himself is a 3-4s invulnerability window that beats almost any early 2-man gank attempt Why this is shown: Viscous's laning strengths. Strong evidence
• What you can take from them in lane: Slow projectile weapon means he loses raw last-hit and harass duels against hitscan laners Why this is shown: Viscous's laning weaknesses. Strong evidence
• What you can take from them in lane: The Cube's cast range was cut to 20m in the 09-16-2026 patch, so cross-lane saves are harder Why this is shown: Viscous's laning weaknesses. Strong evidence
• Your lever: The melee-reload loop from Blasted means he never has to stop shooting to reload in an extended lane trade Why this is shown: Billy's laning strengths. Strong evidence

Mid game

• Their spike — The Cube unlock: A 3s full invulnerability save for any ally changes the maths of every early skirmish and gank Why this is shown: Viscous's power spike timeline. Strong evidence
• Their spike — ult unlock: Goo Ball gives him teamfight initiation, repeated stuns and a durable escape all at once Why this is shown: Viscous's power spike timeline. Strong evidence
• Their spike — The Cube T3: Debuff removal turns the Cube from a save into a hard cleanse for anti-heal, Vyper dagger stacks and Crow bleed Why this is shown: Viscous's power spike timeline. Strong evidence
• Their spike — late 35min+: Goo Ball T3 (18s duration, 0.8s stuns, 55% resists) is a full-teamfight disruption window on a roughly 125s cooldown Why this is shown: Viscous's power spike timeline. Strong evidence
• Your spike — Bashdown T2 (+1 charge, +2m radius): Two charges turn his anti-air pull and knockup from a single interrupt into continuous area control Why this is shown: Billy's power spike timeline. Strong evidence
• Your spike — Blasted T2: The Bashdown charge refund plus +7% wrecked amplification ties his damage engine to his CC and roughly doubles his effective output in a sustained brawl Why this is shown: Billy's power spike timeline. Strong evidence
• The first Unstable Rift lands around 11:00 and then every 7 minutes, and Viscous beats you in exactly the fight it creates. Use the telegraph: a world-only visual appears on a random side-lane bridge roughly 60 seconds before the global announcement and map marker, which is the single biggest piece of free information in the mid game. Spend those 60 seconds either grouping or deliberately taking something elsewhere — the one thing you cannot afford is arriving at a Rift bridge late and alone. Why this is shown: First Unstable Rift ~11:00 (±1 min) then every 7 minutes; ~60s world-visual warning precedes the global announcement. Strong evidence
• Your kit is built around lockdown and that is worth less on the Mid Boss than on Viscous — it carries 35% Debuff Resist as of 03-06-2026, so your disables run roughly two-thirds as long on it. Plan the take around damage and positioning rather than a CC chain, and spend the chain on Viscous if they contest. The payoff is worth the trip: 3,000 souls plus 50 per minute, two permanent buffs each, and a Rejuvenator crystal giving up to three single-use revives that return a player at full health after 3 seconds, for 3 minutes. Why this is shown: Mid Boss has 35% Debuff Resist (03-06-2026); reward is 3,000 souls +50/min, two buffs, and Rejuvenator revive credits. Verified

Teamfights

• Against Viscous's knockups, Debuff Reducer is a live answer where it used to be a dead one: knockup durations were brought under debuff reduction on 05-22-2026, so the +25% from a 1,600 Tier II item genuinely shortens the airborne time. That matters more for you than for most, because you have no exit and the airborne window is when their follow-up lands. Worth pairing with the fact that Knockdown-style effects going the other way still cannot be shortened at all. Why this is shown: 05-22-2026 made knockup durations scale with debuff reduction; Debuff Reducer is T2, 1,600, +25%. Verified
• Fights against Viscous recur on the objective clock — the Rift every 7 minutes from about 11:00, the Urn every 5 from 10:00 — which means the question is not whether your ultimate is strong but whether it is up for the next one. Ultimate Cooldown Reduction is a new stat introduced on 09-16-2026, first appearing on Diviner's Kevlar at +10%. Against a team-fight hero, buying into a recurring ultimate is a different and often better purchase than buying into a bigger one. Why this is shown: 09-16-2026 introduced Ultimate Cooldown Reduction, first granted by Diviner's Kevlar at +10%; Rift cadence is 7 minutes. Verified

Positioning

• Viscous wins by choosing where the fight happens. Take your position before the zoning goes down, not after — once the area is committed you are fighting on their terms, and walking in to contest it is exactly the mistake the kit is built to farm. Why this is shown: Zone-control kits convert space into damage; positioning must precede the cast. Strategic

Build adjustments

• Viscous heals through damage, so healing reduction is not optional here — but pick the right application route. Anti-heal arrives two ways: bullet-applied (Toxic Bullets, T3) builds up through gunfire, and spirit-applied (Healbane, T2) lands off spirit damage. Buy the one that matches how you actually deal damage, or it will never apply. Why this is shown: Anti-heal application routes differ by damage type; mechanics research, patch 09-16-2026. Verified
• Do not assume Viscous shrugs off your anti-heal by going immune. Unstoppable explicitly does not suppress healing reduction — if you have the debuff on them before they pop it, they are still healing at the reduced rate through the whole window. Why this is shown: Documented mechanic: Unstoppable does not suppress healing reduction. Verified
• Majestic Leap (vitality T3) — Viscous gives this team real zoning and area denial. Buy to escape ground-based lockdown and to rotate across the map quickly. Why this is shown: Answers: enemy-zone-control, enemy-hard-cc. Verified
• Stamina Mastery (vitality T3) — Viscous gives this team real stuns and hard cc. Buy when dodging telegraphed abilities and disengaging is how you survive. Why this is shown: Answers: enemy-hard-cc, enemy-zone-control. Strong evidence
• Warp Stone (vitality T3) — Viscous gives this team real stuns and hard cc. Buy when you are repeatedly getting caught and killed out of position, or to close a gap onto a fleeing target. Why this is shown: Answers: enemy-hard-cc, enemy-zone-control. Verified

Common mistakes

• The instinct here is to buy Dispel Magic as your answer to Viscous and then find it greyed out at the exact moment you need it. Dispel Magic cannot be cast while you are stunned or asleep, and it cannot remove a stun at all — it purges what comes with the stun, not the stun itself. Against Viscous the item you actually want is the pre-cast kind (Unstoppable, which also cannot be activated once you are already stunned) or the automatic kind (Indomitable, which cleanses the next hard CC with no input from you). Why this is shown: Dispel Magic cannot be used while stunned or asleep and cannot purge stuns; Unstoppable has the same activation restriction. Verified
• The losing pattern against Viscous is deciding to leave, walking to the zipline and finding you cannot attach. Any damage from an enemy hero or objective blocks zipline attachment for 3 seconds, and Viscous has the chip range to keep that 3-second timer rolling indefinitely. Break line of sight first, wait out the lockout, then attach — do not walk to the rope while still taking fire. Why this is shown: Zipline attachment is blocked for 3s after taking enemy hero or objective damage; enemy rangedPoke 2+. Verified
• The Unstable Rift capture point is a 20m circle on a bridge, capture only progresses when no enemy is inside it, and everyone standing in it is revealed on the minimap. That is a purpose-built trap for Viscous. The mistake is treating the circle as the objective: you do not need to stand in it, you need them not to. Contest from outside the radius, deny with a single body at the edge, and let their area damage land on empty bridge. Why this is shown: Unstable Rift: 20m capture radius, progress halts while any enemy is inside, occupants revealed on the minimap. Strategic
