Mo & Krill vs Viscous

Do

• 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 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 laners with faster bullets
• The Cube's cast range was cut to 20m in the 09-16-2026 patch, so cross-lane saves are harder
• 930 base health gives them a large health pool that is hard to push out of lane.

Avoid

• Splatter's bounces and puddles clear minion waves and hold a lane choke without him needing to step forward
• The Cube on himself is a 3-4s invulnerability window that protects him from an early 2-man gank attempt

Do

• Their first real spike is The Cube unlock — respect it from that point, not before.
• Your spike is Scorn Scorn 13s Cooldown A burst of damage to everything close by that converts a portion of the damage dealt into healing, with a substantially larger return when the damage lands on enemy heroes. Crowd Control None at base. T3 adds a stacking 15% damage debuff on enemies hit, lasting… Damage 45 damage base, scaling with spirit at 0.675, with a 13s base cooldown. Defensive The heal is the main defensive layer. 1 +30 damage. 2 -5s cooldown, +1m radius. 5 applies a stacking 15% damage debuff to enemies hit for 16s. first two points (laning 0-10min): The Scorn/Scorn opener front-loads their sustain and wave clear.

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 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 is on cooldown.

• Goo Ball 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 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 20 damage base plus 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 (Yamato's Shadow Transformation Shadow Transformation 5s Duration160s Cooldown Yamato transforms with an initial invincible window, refreshes her ability cooldowns, and for the duration casts them much faster while immune to negative status effects and heavily… Damage No direct damage; the power is in refreshed abilities cast 60% faster Mobility T2 adds +4 m/s move speed during the transformation, on top of her already… Defensive Initial invincibility during the 1.5s transformation channel, immunity to… 1 +7 weapon damage 2 +4 m/s move speed and -30s cooldown (160s base) 5 +3s duration (5s base up to 8s) and +30% bullet resist and +30% spirit resist status immunity) ignore the Knockup entirely
• Splatter 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
• The Cube 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 first, always — it only protects one hero, so forcing it out early is the plan against Viscous

2. 2 Puddle Punch

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

• 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% Strong evidence
• Very low personal damage output — he needs a team to convert his setups Strong evidence
• Goo Ball is much weaker in open ground where there is nothing to bounce off and no clumped target 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

• The Cube makes your committed burst vanish — an Assassinate Assassinate 55s Cooldown Scopes in for a long-range rifle shot. Damage 90 base spirit plus up to 90 bonus against targets under 50% health (T2 adds… Mobility none — she is scoped and stationary during the charge 1 -15s cooldown (55s base) 2 +80 maximum bonus damage 5 +4% weapon damage per kill (from +6% to +10%) , Ira Domini Ira Domini 15s Duration160s Cooldown For a limited window Venator loads three heavy stakes instead of normal bolts.

Crowd Control stunned during the 1.25s channel, then the target is airborne and unable to… Damage 100 spirit base (about 1.0x spirit scaling); Mobility none for Wraith — she channels for 1.25s while aiming the throw 1 +100 damage 2 -45s cooldown (150s base down to 105s) 5 +1.5s debuff duration and +6m throw and cast range slam or Petrifying Bola Petrifying Bola 115s Cooldown Throws an explosive bola. Crowd Control 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); Damage 50 area damage (about 0.74x spirit scaling); Defensive Petrifying an incoming diver removes them from the fight for over two… 1 +49.5 petrify damage 2 -20s cooldown 5 +1s petrify duration and petrifies all enemies in the area, not just direct hits aimed at a cubed ally deals literally nothing, and they come out healed Strong evidence
• Puddle Punch reaches 40m and knocks you up, cancelling Assassinate's scope, Warden's 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. Crowd Control none directly — its power comes from being paired with Binding Word Damage 70 DPS base (about 1.3x spirit scaling) over 6s in a 12m radius; Mobility none, and he is channelling 1 +4m radius (12m base up to 16m) 2 +50 DPS and -40s cooldown (180s base) 5 +4s duration and +30% resists while channelling charge, Yamato's Power Slash Power Slash 12s Cooldown Yamato channels for around a second and a half to build up a sword strike, then releases it as a ranged slash. Crowd Control T1 adds a 32% movement slow for 3s Damage 145 spirit at full charge (about 1.96x spirit scaling), with T3 adding +150… Mobility none — she is channelling 1 +32% movement slow for 3s 2 -4s cooldown (12s base) 5 +8m cast range, +150 damage, and increased Spirit Power scaling , or any channel you are committed to 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 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 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 Strong evidence

• 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 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 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 Strong evidence
• Save a Hard CC (Warden's Binding Word Binding Word 15m Range34s Cooldown Curses a targeted enemy hero. Crowd Control 1.75s immobilise (T2 adds +0.75s, so up to 2.5s) if the target fails the… Damage 110 (about 2.44x spirit scaling) when it lands Defensive Rooting a diver in place is a strong self-peel 1 Warden deals +20% bullet damage to trapped heroes for 5s 2 +0.75s immobilise duration 5 -14s cooldown (34s base) and silences the target until they escape or are immobilised , Vindicta's Stake Stake 40s Cooldown Throws a stake that embeds where it lands.

• Do not fight inside his Splatter puddles; route around them, because the 28% slow is the setup for everything else he does Strong evidence
• Viscous contributes through abilities, which makes a hard Silence worth more against them than any amount of resist. Focus Lens Focus Lens 6,400 souls Tier 4TechPress +40s Cooldown +4.5s Duration +0.1s Cast Delay +35% Damage On Expire +10% Fire Rate -9% Spirit Resist -30 Spirit Power +12s Resist Reduction Duration Builds from Spirit Sap 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. Strong evidence

• 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 Strong evidence
• The 22-42s after The Cube is spent: his team has no save and his own escape is gone Strong evidence
• After Puddle Punch's single base charge is used (24s cooldown post-09-16-2026), any channelled ability is safe Strong evidence
• In open terrain with no walls, Goo Ball's trajectory is predictable and largely dodgeable Strong evidence
• His slow projectile weapon means constant lateral strafing at range makes his chip damage miss 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. 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 + 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. Documented

• 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

• You deal Spirit Damage, so Healbane Healbane 1,600 souls Tier 2ArmorPassive +8s Duration +7 Spirit Power -35% Incoming Healing is the cheaper and more reliable anti-heal against Viscous — it lands off your abilities at T2 rather than asking you to sustain gunfire you are not built for. Strong evidence
• 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. Documented
• Majestic Leap (vitality T3) — Viscous' Splatter — that is the zoning and area denial this answers. Buy to escape ground-based lockdown and to rotate across the map quickly. Documented
• Stamina Mastery Stamina Mastery 3,200 souls Tier 3ArmorPassive +2 Stamina +18% Stamina Recovery +23% Air Jump/Dash Distance Builds from Extra Stamina (vitality T3) — Viscous' Goo Ball — that is the stuns and Hard CC this answers. Buy when dodging telegraphed abilities and disengaging is how you survive. Strong evidence
• Warp Stone Warp Stone 3,200 souls Tier 3ArmorInstantCast +16s Cooldown +30% Bullet Resist +6s Buff Duration (vitality T3) — Viscous' Goo Ball is what you are buying against here. Buy when you are repeatedly getting caught and killed out of position, or to close a gap onto a fleeing target. Documented

• Your instinct is to jump on Viscous's backline the moment you see an opening, and the mistake is not checking what is above you. A Walker's Stomp is 350 damage + 15% of your max health inside 15m with a 2-second Stun on a 7-second cooldown — a 2-second Stun handed to a team with peel is a death. Dive under their Walker only with Unstoppable pre-cast or after the Stomp has just gone off. Strong evidence
• 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
