Playing Ivy against Mo & Krill

What should I do right now?

Matchup overview

• Their structural weakness: No ranged damage whatsoever; kiting them is the single most effective strategy against them. Why this is shown: Mo & Krill's weaknesses. Strong evidence
• Their structural weakness: Combo is a stationary channel that any CC breaks, wasting their most important cooldown. Why this is shown: Mo & Krill's weaknesses. Strong evidence
• Their structural weakness: Anti-heal items simultaneously disable Scorn's sustain and Combo T1's lifesteal. Why this is shown: Mo & Krill's weaknesses. Strong evidence
• You fight at mid range and Mo & Krill has to reach close range, but they have the movement to do it — which means the matchup is not a range advantage, it is a cooldown one. Their gap-closer is the only thing bridging the band, so track it rather than tracking their health. With it up you are in their range and should behave accordingly; with it down you are in a range they cannot reach and every second of that window is free. Why this is shown: Mid-range hero versus a close-range opponent with mobility 2+; the gap-closer cooldown gates the entire matchup. Strategic
• 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 Mo & Krill 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

• Burrow lets them travel to you underground with bullet and spirit armour, then surface directly under your feet with a knockup you cannot dash out of. Why this is shown: Authored from Mo & Krill's kit. Strong evidence
• Sand Blast disarms you for around 2.5s (longer at T3) in a 25m cone — your gun stops working for the exact seconds they need to set up. Why this is shown: Authored from Mo & Krill's kit. Strong evidence
• Combo holds you stunned in place for roughly 3 seconds while grinding through your health, with +50% bullet resist at T2 so shooting them off is unreliable. Why this is shown: Authored from Mo & Krill's kit. Strong evidence
• Scorn heals them off every body in radius, with a stacking 15% damage debuff on you at T3 — the longer the brawl runs, the more the numbers move their way. Why this is shown: Authored from Mo & Krill's kit. Strong evidence
• Every kill secured inside Combo permanently raises their max health, so the same hero is measurably harder to kill in minute 40 than in minute 20. Why this is shown: Authored from Mo & Krill's kit. Strong evidence
• Your mobility is a real advantage here, and Mo & Krill's slows exist to delete it. Note that Debuff Resist barely helps against short hard slows because it only trims duration — spacing and cover do more than an item will. Why this is shown: Debuff Resist reduces duration only; short slows are largely unaffected. Strong evidence

How you counter them

• Kite. Their entire damage output requires close range and their spreadshot does 2.8 per pellet — holding 15m+ with a mid- or long-range hero makes them a non-threat. Why this is shown: Authored counterplay against Mo & Krill. Strong evidence
• Shoot the burrow mound as it approaches. Hero damage reduces the Burrow speed bonus directly, so contesting the travel converts their dive into a walk. Why this is shown: Authored counterplay against Mo & Krill. Strong evidence
• Hold one interrupt specifically for the Combo channel. Any stun, silence, knockup or displacement on them cancels a 150-second ultimate and denies the permanent health stack. Why this is shown: Authored counterplay against Mo & Krill. Strong evidence
• Buy anti-heal before mid game. Healbane / Toxic Bullets cut Scorn's healing and Combo T1's lifesteal at the same time. Why this is shown: Authored counterplay against Mo & Krill. Strong evidence
• Spread out so the Burrow emergence knockup and Scorn each hit one person instead of three — their sustain scales with the number of bodies in radius. Why this is shown: Authored counterplay against Mo & Krill. Strong evidence
• Sand Blast is a frontal cone: circle behind them rather than backing straight up, and if you are ability-based, keep fighting through the disarm since it only blocks weapons. Why this is shown: Authored counterplay against Mo & Krill. Strong evidence
• You do not have the CC to reliably break Combo out of your own kit, so buy the cheapest thing that does: Silence Wave is the only area silence in the shop and the standard answer to channelled ultimates. Area matters because you do not have to win the aim duel — you have to cover the spot they cast from. Note the alternative, Counterspell, parries a single ability outright but requires a read; Silence Wave forgives a bad read, which is why it is the buy when interrupting is not your specialty. Why this is shown: Silence Wave (T3 Spirit) is the only area silence; Counterspell negates a single ability but requires prediction. Strong evidence
• You have an immunity window and Mo & Krill has a burst combo, which makes this a timing matchup rather than a damage one. Their combo has a commit point; your window has to cover that point rather than open before it. Using it early is the same as not having it. Why this is shown: Hero with an immunity window facing a burst 2+ opponent. Strategic

Trading

• During the Combo channel — they are stationary, locked to one target, and any hard CC cancels it. This is the single best punish in their kit. Why this is shown: Mo & Krill's vulnerability windows. Strong evidence
• While burrowed and being shot: hero damage strips the speed bonus, so a contested approach leaves them arriving late and out of position. Why this is shown: Mo & Krill's vulnerability windows. Strong evidence
• Immediately after the Burrow emergence knockup, with Burrow on cooldown — they have no escape and are standing inside your team. Why this is shown: Mo & Krill's vulnerability windows. Strong evidence
• Any time they are further than ~10m from a target; their spreadshot falloff and Scorn radius mean they simply cannot deal damage at that range. Why this is shown: Mo & Krill's vulnerability windows. Strong evidence
• Their 2.82s spreadshot reload at close range, which is a long window for a hero with no ranged fallback. Why this is shown: Mo & Krill's vulnerability windows. Strong evidence
• Being stunned by Mo & Krill 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
• Parry is your best tool against Mo & Krill's arrival and it is now a commitment rather than a hedge. Since 09-16-2026, parrying during a dash cancels the dash and its momentum, so you cannot both reposition and hold F. The cooldown maths makes the decision for you: a successful parry costs 0.5 seconds and stuns them for 3 with no Debuff Resist reduction possible, while a whiff costs 4.5 seconds — against a hero who arrives on a cooldown, that whiff is the entire window they needed. Why this is shown: 09-16-2026 parry cancels an in-progress dash; parry cooldown 0.5s on success, 4.5s on whiff; 3s unreducible stun. Verified

Laning

• What they want in lane: 930 base health is one of the largest pools in the game and makes them extremely hard to push out of lane. Why this is shown: Mo & Krill's laning strengths. Strong evidence
• What they want in lane: Scorn clears troopers and heals off them simultaneously, so they sustain and farm from the same button — the top opener is Scorn, Scorn, Sand Blast at 66.9% WR (deadlocklabs.gg). Why this is shown: Mo & Krill's laning strengths. Strong evidence
• What you can take from them in lane: Zero ranged presence — 2.8 damage per pellet means they contribute essentially nothing outside a few metres. Why this is shown: Mo & Krill's laning weaknesses. Strong evidence
• What you can take from them in lane: Every one of their damage tools requires being close, so a mid- or long-range laning duo can simply refuse to engage. Why this is shown: Mo & Krill's laning weaknesses. Strong evidence
• Your lever: Entangling Thorns clears the wave and denies the orb area at the same time Why this is shown: Ivy's laning strengths. Strong evidence
• Your escape route is vertical and the 09-16-2026 patch aimed at exactly that: slows now affect air drag at 35% of their value, where previously they mostly did not bite in the air. Going airborne to break Mo & Krill's slow no longer restores your full movement — you carry a fraction of it into the air with you, at the moment you are also a stationary silhouette. The slow cut of ~20% partly offsets it, but the net is that air-escaping a slow is worse this patch than last. Why this is shown: 09-16-2026: slows now apply to air drag at 35% of their value, alongside the ~20% global slow reduction. Verified
• You get value from moving around the map and Mo & Krill does not, but the 09-16-2026 patch made that harder to convert early: tunnel breakables now spawn and respawn on 5 minutes rather than 3. The off-lane income that used to make a rotation pay for itself is roughly 40% less frequent, so before 6:00 a rotation has to be justified by pressure on Mo & Krill or on the Guardian, not by the breakables you pick up on the way. Why this is shown: 09-16-2026: underground tunnel breakable initial spawn and respawn both raised 3 → 5 minutes. Verified

Mid game

• Their spike — Scorn first two points (laning 0-10min): The Scorn/Scorn opener front-loads their strongest sustain and lets them snowball the lane (66.9% WR per deadlocklabs.gg). Why this is shown: Mo & Krill's power spike timeline. Strong evidence
• Their spike — Combo unlock: They gain the game's longest reliable single-target removal, plus the permanent max-health stacking mechanic starts. Why this is shown: Mo & Krill's power spike timeline. Strong evidence
• Their spike — Combo T2 (mid game): -30s cooldown and +50% bullet resist make the ultimate both repeatable and much harder to break with gunfire. Why this is shown: Mo & Krill's power spike timeline. Strong evidence
• Their spike — Burrow T3 (late): -20s cooldown and +4 m/s make them a rotating map threat who can arrive at any fight under armour. Why this is shown: Mo & Krill's power spike timeline. Strong evidence
• Your spike — ult unlock: Air Drop turns every fight into one her team can start from an angle the enemy cannot defend Why this is shown: Ivy's power spike timeline. Strong evidence
• Your spike — Kudzu Connection tier 3: The connection becomes always-on, so the buff no longer depends on holding line of sight Why this is shown: Ivy's power spike timeline. Strong evidence

Teamfights

• Combo is a channel, which means the fight is decided by whether you can break it. Hold one interrupt — a stun, a silence, or a displacement — specifically for that cast rather than spending it on the opening trade. If you have no interrupt, the answer is line of sight: leave the area entirely rather than trying to out-heal it. Why this is shown: Channelled ultimates are interruptible by hard CC, silence or displacement. Strong evidence
• Your silence may be worth more in a chain than a teammate's stun. The 03-06-2026 diminishing-returns system reduces subsequent CC by 10% then 30% inside an 8-second window, and community reporting holds it applies to stuns only — not to silences, slows, hexes or disarms. If that is right, sequencing your silence after an ally's stun costs you nothing, while a second stun in the chain is already 10% shorter. Treat it as community-reported rather than confirmed, but order your chain accordingly against Mo & Krill. Why this is shown: CC diminishing returns of 10%/30% in an 8s window (03-06-2026); the stun-only scope is a single community source. Uncertain
• You are not going to kill Mo & Krill in a normal teamfight and trying to is how fights are lost. Treat them as terrain: fight around them, spend your damage on whoever is behind them, and only commit to killing them once anti-heal and shred are actually online. Why this is shown: Enemy durability 3 with a frontline role; target-priority reasoning. Strategic
• You have peel and Mo & Krill is the dive threat, so your job in the fight is not damage — it is being in range of whoever they are jumping on. Position between their entry point and your squishiest teammate and hold your peel tool for the moment they commit, not for the moment they appear. Why this is shown: Hero has peel 2+ against a high dive threat. Strategic
• Mo & Krill brings enough lockdown that stun sequencing matters. Community reporting describes stun diminishing returns of roughly 10% then 30% inside an 8-second window, applying to stuns only and not to silences, slows, disarms or hexes — so their follow-up chain may be shorter than the first one felt. Treat this as unconfirmed, but it is worth knowing before you burn a cleanse on the opening stun. Why this is shown: Stun diminishing returns reported by community sources; not confirmed in official notes. Uncertain

Positioning

• Your habit of taking the fight vertical to reset spacing against Mo & Krill is weaker on 09-16-2026 than it was. Slows now apply to air drag at 35% of their value, so the air is no longer a slow-free zone, and 2026 has been a steady closing of exactly these loopholes — wall jumping costs 25% stamina regeneration for 5 seconds, and knockups came under debuff reduction in May. Going up is still correct against their ground CC; it is no longer a way to ignore their slows. Why this is shown: 09-16-2026: slows affect air drag at 35% of value; 05-22-2026 added the wall-jump stamina penalty and brought knockups under debuff reduction. Verified

Build adjustments

• Mo & Krill 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
• Against Mo & Krill's crowd control, understand what Debuff Resist actually buys you: it shortens duration, never magnitude. It is excellent against long disables and close to worthless against a short hard slow. Two things it explicitly does not shorten at all are the parry stun and the Knockdown item's stun. Why this is shown: Debuff Resist reduces duration only; parry stun and Knockdown stun are documented exclusions. Verified
• Mo & Krill is a durability check, and the maths favours shred over raw damage here. Resistances stack multiplicatively, but shred is pooled and then subtracted from total resist — so the higher their resist climbs, the more each point of shred is worth. Against a stacked tank, resist reduction outperforms another flat damage item. Why this is shown: Resist stacking is multiplicative; shred subtracts from total resist, so its value scales with target resist. Verified
• If Mo & Krill buys Dispel Magic to purge your anti-heal, bullet-applied reduction re-lands on your very next shot, while spirit-applied reduction has to wait for your next ability. That asymmetry is a real argument for the bullet route against a hero who will buy a purge. Why this is shown: Dispel Magic purges non-ultimate debuffs; bullet-applied anti-heal reapplies on the next bullet. Strong evidence
• Unstoppable (vitality T4) — Mo & Krill gives this team real stuns and hard cc. Buy when enemy lockdown is the reason you lose fights — it lets you walk through a full CC chain and still deal damage. Why this is shown: Answers: enemy-hard-cc, enemy-channeled-ult, enemy-silence, enemy-displacement. Verified
• Ethereal Shift (spirit T4) — Mo & Krill gives this team real channelled ultimates. Buy to survive a telegraphed assassination combo or ultimate — you simply cease to be a target for four seconds. Why this is shown: Answers: enemy-channeled-ult, enemy-backline-threat, enemy-dive, enemy-burst. Verified
• Knockdown (spirit T3) — Mo & Krill gives this team real gap closers and escapes. The consensus answer to flying and airborne heroes and to channelled aerial ultimates — buy it whenever an enemy fights from the sky. Why this is shown: Answers: enemy-mobility, enemy-channeled-ult, enemy-backline-threat. Verified

Common mistakes

• Anti-heal against Mo & Krill is bought correctly and applied at the wrong moment. Healbane's reduction runs for 8 seconds from your spirit damage and Toxic Bullets' runs while the bleed is up — both are windows, and re-applying the same source before it expires does not stack a second instance. The mistake is opening the fight clean and reaching for anti-heal once they start healing; by then you have spent the fight. Land it before they commit, then keep the window refreshed rather than re-triggering it. Why this is shown: Healbane applies for 8s on spirit damage; same-source healing reduction does not stack on re-application. Strong evidence
• The reflex buy against a hero who keeps deleting you is Metal Skin, and against Mo & Krill it does nothing. Metal Skin is bullet-damage immunity only — spirit damage, abilities and every status effect pass straight through it, and you pay −1.5 m/s move speed and −20% dash distance for the privilege. The three big defensive actives are deliberately orthogonal: Metal Skin stops bullets, Unstoppable stops statuses, Ethereal Shift stops everything but disables you. Mo & Krill is a spirit threat, so it is the last two you are choosing between. Why this is shown: Metal Skin blocks bullet damage only; enemy damage profile is spirit with burst 2+. Verified
• If you learned to play this matchup before 09-16-2026 you probably dash away from Mo & Krill and parry on the way out. That no longer works: parrying during a regular dash now cancels the dash and its momentum, so you parry standing still exactly where they wanted you. Parry first and dash second, or accept that the parry is a commitment to hold ground. Note also that a whiffed parry is a 4.5-second cooldown against a hero who only needs one window. Why this is shown: 09-16-2026: parrying mid-dash cancels the dash and its momentum; parry whiff cooldown 4.5s. Verified
• The finishing heavy melee on Mo & Krill is worse than it feels. Melee damage is mitigated twice — once by Bullet Resist and again by Melee Resist — so it is the single worst damage channel to point at a stacked-resist target, and the wind-up is long enough for a parry that stuns you for 3 seconds with no Debuff Resist reduction available. Finish with your gun or an ability, not with melee. Why this is shown: Melee is reduced by both Bullet Resist and Melee Resist; the parry stun is 3s and is not shortened by Debuff Resist. Strong evidence
• Players buy Dispel Magic for Mo & Krill and then discover it does nothing about Combo. Dispel Magic purges non-ultimate negative effects only — anything sourced from an ultimate is outside its scope entirely. Work out which of Mo & Krill's disables come off abilities and which come off the ult before you spend 3,200: the ability-sourced ones are purgeable, the ult is not, and for the ult you need either Unstoppable pre-cast or the discipline not to be there. Why this is shown: Dispel Magic cannot purge ultimate-sourced debuffs; enemy cc 3 with a hard disable tag. Verified
• Your damage arrives over time and Mo & Krill converts damage dealt into health, which makes the natural instinct — stay in the fight, keep the pressure on — the exact thing that loses it. Their sustain scales with how many targets are in front of them and how long the fight runs; yours does not scale at all. Either break contact and force them to re-approach on a cooldown, or bring healing reduction so the long fight stops being their format. Why this is shown: Enemy lifesteal-core against a hero with burst 0-1; lifesteal scales with fight length and target count. Strategic
