• Plan for Majestic Leap Majestic Leap 3,200 souls Tier 3ArmorInstantCast +45s Cooldown +5s Interrupt Cooldown +100% Air Control +50% Air Control +32% Move Speed +2.5s Slow Duration +8s Barrier Duration — know which tier it sits in so you are not improvising at the shop.
• Know what The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) looks like. It is the cooldown this lane revolves around.

Avoid

• Walking to lane on the same path every wave against a hero with Viscous's engage range.

Do

• Slow projectile weapon means he loses raw last-hit and harass duels against hitscan laners
• The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) 's cast range was cut to 20m in the 09-16-2026 patch, so cross-lane saves are harder
• Scrap Grenade Scrap Grenade 26s Cooldown Rat King throws a bouncing lump of scrap that goes off three times where it lands. Crowd Control 20% movement slow for 4s (scales slightly with Spirit). Damage 70 bullet damage per detonation (+0.6 weapon-damage scaling), three… Defensive The slow is his peel: thrown at his own feet it stops a diver from following… 1 -8s cooldown (26s to 18s) 2 +70 damage per detonation 5 one extra, bigger final detonation — 300 damage, 14m radius, 40% slow clears a trooper wave in three hits and slows anyone farming in it, so he wins wave tempo early

Avoid

• Splatter Splatter 26s Cooldown Throws a ball of goo that damages what it hits and bounces a couple of times, leaving behind puddles that slow any enemy standing in them for around ten seconds. Crowd Control -28% movement slow to enemies standing in the puddles Damage 55 base (about 0.7x spirit scaling); Defensive The puddles slow chasers, which is a soft disengage 1 +36 damage and +1.5m radius 2 -14s cooldown (26s base) 5 one additional bounce and improved spirit scaling 's bounces and puddles clear minion waves and hold a lane choke without him needing to step forward

• Their first real spike is The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) unlock — respect it from that point, not before.
• Your spike is ult unlock: Rule, Ratannia! Rule, Ratannia! 10s Duration160s Cooldown Rat King raises the banner of Ratannia.

Avoid

• Taking an even fight against Viscous on their spike timing when you could take the same fight ten minutes later on yours.

Do

• Watch for Goo Ball Goo Ball 11s Duration150s Cooldown Viscous becomes a large ball of goo that rolls around the map, damaging and briefly stunning any enemy it slams into. Crowd Control 0.5s stun on impact (T3 adds +0.3s); Damage 110 base (about 1.0x spirit scaling); Mobility High-speed rolling with wall bounces and a double jump, for 11s (T3 adds… 1 -25s cooldown (150s base) 2 +70 damage and +20% to both resists 5 +7s duration, +0.3s stun duration, and +0.2 spirit scaling . Spread out. The ball needs impacts to do anything, and a spread formation means each roll hits one person for 110-180 and a 0.5-0.8s Stun instead of the whole team
• Bait The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) out on a target you were going to pressure anyway, then commit your real burst during the 22-42s it is down

Avoid

• Spending your own escape before The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) is on cooldown.

• Goo Ball Goo Ball 11s Duration150s Cooldown Viscous becomes a large ball of goo that rolls around the map, damaging and briefly stunning any enemy it slams into. Crowd Control 0.5s stun on impact (T3 adds +0.3s); Damage 110 base (about 1.0x spirit scaling); Mobility High-speed rolling with wall bounces and a double jump, for 11s (T3 adds… 1 -25s cooldown (150s base) 2 +70 damage and +20% to both resists 5 +7s duration, +0.3s stun duration, and +0.2 spirit scaling Ultimate

  The cooldown that decides the fight. 0.5s Stun on impact (T3 adds +0.3s); repeatable on every collision for the duration.

  • Spread out. The ball needs impacts to do anything, and a spread formation means each roll hits one person for 110-180 and a 0.5-0.8s Stun instead of the whole team
  • Fight in open ground — without walls to bounce off, his steering is far more predictable and easy to sidestep
  • While he is a ball, The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) is unavailable; that is the window to burst his carry, because he cannot save them
• Puddle Punch Puddle Punch 40m Range24s Cooldown Materialises a fist at a chosen point up to a long distance away, punching everyone in a small area upward. Crowd Control Knockup on everyone in the 4m radius plus a -24% movement slow for 3s Damage About 58 melee damage (about 0.6x melee scaling); Mobility Grants Viscous and allies increased air control when caught in it 1 +1 charge and +20 damage 2 +1.5m radius and +60% lifesteal 5 -14s cooldown and deals Heavy Melee damage Ability 3

  It puts you somewhere you did not choose to be — Knockup on everyone in the 4m radius plus a -24% movement slow for 3s.

  • The fist has a visible telegraph at the placement point — sidestep out of the 4m radius during the wind-up
  • Do not start a long channel while you are clumped with teammates in his 40m sight line; force him to spend the charge on a solo target first
  • Unstoppable Unstoppable 6,400 souls Tier 4ArmorInstantCast +60s Cooldown +5.5s Duration +125 Bonus Health +25% Debuff Resist Builds from Debuff Reducer effects (Warden's T3 Last Stand Last Stand 6s Duration180s Cooldown After a two-second charge-up, Warden pulses damage in a wide radius around himself twice a second, healing for a large share of the damage he deals.

• Splatter Splatter 26s Cooldown Throws a ball of goo that damages what it hits and bounces a couple of times, leaving behind puddles that slow any enemy standing in them for around ten seconds. Crowd Control -28% movement slow to enemies standing in the puddles Damage 55 base (about 0.7x spirit scaling); Defensive The puddles slow chasers, which is a soft disengage 1 +36 damage and +1.5m radius 2 -14s cooldown (26s base) 5 one additional bounce and improved spirit scaling Ability 1

  Not lockdown, but it makes disengaging cost more than it should: -28% movement slow to enemies standing in the puddles.

  • The puddles are large and clearly visible on the ground — route around them rather than fighting inside them, since the -28% slow is what makes his Knockup land
  • It is a slow bouncing projectile; strafing sideways during the travel and bounce beats it entirely at range
  • Do not stack your team in a corridor he has pre-puddled, because that is the setup for Goo Ball Goo Ball 11s Duration150s Cooldown Viscous becomes a large ball of goo that rolls around the map, damaging and briefly stunning any enemy it slams into. Crowd Control 0.5s stun on impact (T3 adds +0.3s); Damage 110 base (about 1.0x spirit scaling); Mobility High-speed rolling with wall bounces and a double jump, for 11s (T3 adds… 1 -25s cooldown (150s base) 2 +70 damage and +20% to both resists 5 +7s duration, +0.3s stun duration, and +0.2 spirit scaling
• The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base) Ability 2

  A second source of hard control: the cubed target cannot take new actions for the duration; this applies to the person being cubed, ally or self.

  • Hold your burst ultimate until The Cube is already spent — it is on a 22-42s cooldown and it only saves one person
  • Force it out on a non-critical target (a frontliner you were pressuring anyway), then commit your real damage during the downtime
  • Since the cast range dropped to 20m in the 09-16-2026 patch, killing or displacing Viscous himself, or pressuring the target from beyond 20m, denies the save

1. 1 The Cube The Cube 20m Range3s Duration42s Cooldown Encases a target in a cube of restorative goo. Crowd Control The cubed target cannot take new actions for the duration; Mobility None directly; the cubed hero can escape early via Jump/mantle Defensive Complete invulnerability to all incoming damage for 3s (T2 adds +1s), plus… 1 increases Move Speed and Stamina Recovery (on exit) 2 +25 health regen and +1s duration 5 removes all non-ultimate debuffs from the target and -20s cooldown (42s base)

   The Cube first, always — it is the highest-value single cooldown in his kit and only protects one hero; forcing it early is the whole game plan against Viscous

2. 2 Puddle Punch Puddle Punch 40m Range24s Cooldown Materialises a fist at a chosen point up to a long distance away, punching everyone in a small area upward. Crowd Control Knockup on everyone in the 4m radius plus a -24% movement slow for 3s Damage About 58 melee damage (about 0.6x melee scaling); Mobility Grants Viscous and allies increased air control when caught in it 1 +1 charge and +20 damage 2 +1.5m radius and +60% lifesteal 5 -14s cooldown and deals Heavy Melee damage

   Puddle Punch second: with the 09-16-2026 nerf to 24s (1 charge at base), spending it means your channels are safe for over 20 seconds

3. 3 Splatter Splatter 26s Cooldown Throws a ball of goo that damages what it hits and bounces a couple of times, leaving behind puddles that slow any enemy standing in them for around ten seconds. Crowd Control -28% movement slow to enemies standing in the puddles Damage 55 base (about 0.7x spirit scaling); Defensive The puddles slow chasers, which is a soft disengage 1 +36 damage and +1.5m radius 2 -14s cooldown (26s base) 5 one additional bounce and improved spirit scaling

   Splatter third: it is his cheapest ability and mostly a zone tool; walking around the puddles is better than baiting it

• Currently underperforming (around 47-48% win rate on current-patch samples) Strong evidence
• Nerfed across the board in the 09-16-2026 patch: Cube range 26m to 20m, Puddle Punch Puddle Punch 40m Range24s Cooldown Materialises a fist at a chosen point up to a long distance away, punching everyone in a small area upward.

• Very low personal damage output — he needs a team to convert his setups 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. Strong evidence

• His slow projectile weapon means constant lateral strafing at range makes him miss most of his own chip damage 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. Documented

• Viscous will shove the wave into your Guardian to push you off souls, and you are not fast enough to walk around it. The thing to protect is the floating orb — the ground orb drops and cannot be denied, so half your income is safe no matter what they do, and the contest is only ever over the other 50. Position on your Guardian's side of the wave so you are already in range of the floating orbs when they pop, and give up the forward orbs rather than crossing for them. Strategic

• Against Viscous's knockups, Debuff Reducer Debuff Reducer 1,600 souls Tier 2ArmorPassive +25% Debuff Resist +90 Bonus Health 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 Knockdown 3,200 souls Tier 3TechPress +35s Cooldown +0.1s Cast Delay +2s Stun Delay +0.5s Stun Duration +75 Bonus Health +5% Ability Range +5% Radius -style effects going the other way still cannot be shortened at all.

• 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.

• 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. Strategic
• Viscous has to lead you and you are too slow to make that hard by strafing, so buy the miss with geometry instead of movement. A corner, a pillar or a doorway edge means the projectile has to be in flight before you are visible — travel time works against them the moment the sight line is short-lived. Hold positions where your exposure is measured in fractions of a second per peek, and never cross an open space on a straight line at a constant speed, which is the one input their weapon is designed to punish.

• The instinct here is to buy Dispel Magic Dispel Magic 3,200 souls Tier 3ArmorInstantCast +45s Cooldown +10% Spirit Resist +3s Buff Duration +250 HP Healed On Activate as your answer to Viscous and then find it greyed out at the exact moment you need it. Dispel Magic Dispel Magic 3,200 souls Tier 3ArmorInstantCast +45s Cooldown +10% Spirit Resist +3s Buff Duration +250 HP Healed On Activate 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.

• 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. Documented
• The specific error is walking into Viscous's area denial after it is already down, because your team is in there and you feel late. You are slow enough that entering a committed zone is a one-way decision — you will be inside it for its full duration, not for the two seconds you intended. Arrive before the zone or arrive from the other side of it; arriving into it is how this matchup is lost even when your team wins the fight. Strategic
• 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. Strategic
