Mo & Krill Deadlock Guide (2026): Build, Abilities & Combo

Updated July 21, 2026: Mo & Krill are a high-complexity brawler with area damage and healing, protected underground movement, a cone disarm, and a channeled hold that can permanently increase maximum health.

Mo & Krill want to enter under pressure rather than walk through it. Burrow supplies speed and defenses, its emerge creates the opening, Sand Blast removes nearby weapon pressure, Scorn converts close contact into health, and Combo holds the chosen target long enough for the team to act.

Current meta snapshot: Tracklock’s standard-mode, all-rank table showed Mo & Krill at a 28.69% pick rate and 51.25% win rate when checked July 21. These numbers move as matches arrive; they explain why this guide exists, not what every future patch will look like.

Mo & Krill At A Glance

Mo & Krill Abilities

The kit is durable but still sequencing-dependent. Burrow should deliver Mo & Krill to a fight the team can reach, Sand Blast should remove the most dangerous weapon response, and Combo should begin only after obvious interrupts are accounted for. Scorn then rewards staying near heroes instead of chasing into empty space.

Best Mo & Krill Ability Order

Tracklock’s largest completed skill-max route on the July 9 patch prioritized:

1. Burrow
2. Scorn
3. Combo
4. Sand Blast

This is the largest completed max-order route in the current standard-match sample. It prioritizes entry and mobility, then repeatable sustain. Combo remains central to picks and permanent-health growth even when its final upgrades arrive third.

Mo & Krill Build

Tracklock currently shows only 58 pro games for this rolling sample, so treat the item frequencies as directional. The coherent idea is a Spirit brawler who reaches the target, survives close contact, and repeats control. Healbane, Torment Pulse, duration, cooldown, and Warp Stone all support that job.

This is a dated route, not a shopping script. Check the live Mo & Krill pro-build sample, compare alternatives in the Deadlock builds guide, and use the items guide when the enemy composition demands a counter purchase.

Situational Purchases

• Buy Debuff Reducer when silence or control prevents Burrow from becoming a reliable exit.
• Use Knockdown when the team needs another interrupt before Mo & Krill can reach Combo range.
• Choose Colossus against a composition that must focus Mo & Krill during a long objective fight.

How To Play Mo & Krill

Lane

Use Scorn on both the opponent and wave when possible, but do not spend health just to force contact. Burrow can avoid a losing firing line or punish an overextended enemy; emerge where Sand Blast can disarm the return trade.

Mid Game

Approach from terrain that hides the Burrow path. Emerge under the exposed target, Sand Blast the strongest nearby weapon threat, and channel Combo only when allies are close enough to earn the kill and permanent-health window.

Teamfights

Burrow through the first projectile pressure and surface near the backline without abandoning the front. Scorn several heroes, disarm the main carry, and use Combo on the target whose removal changes the fight rather than the easiest tank to grab.

Late Game

Permanent health does not excuse a solo entry. Track enemy interrupts, keep Warp Stone or Burrow available for the second movement, and favor a protected channel that allies can convert over a spectacular hold in the middle of six enemies.

Mo & Krill Combos And Fight Patterns

• Standard entry: Burrow along cover, emerge under the target for knockup and slow, Sand Blast the response, then Combo while allies focus the held hero.
• Sustain brawl: emerge among several enemies, trigger Cold Front or Torment Pulse, use Scorn for hero healing, then reposition before the next Scorn cycle.
• Defensive peel: Sand Blast the weapon threat, Burrow beneath the pursuit, emerge to knock up the chase, then Combo the most dangerous diver if allied damage is ready.

Mo & Krill Strengths And Weaknesses

How To Counter Mo & Krill

• Damage Burrow to reduce its movement advantage and predict the emerge point.
• Save an interrupt or displacement for the Combo channel.
• Spread enough that Scorn and emerge cannot hit the whole team.
• Use Spirit resistance and anti-heal during the close brawl.
• Force Mo & Krill to surface before the priority target commits.

Common Mo & Krill Mistakes

• Burrowing directly through vision with no alternate emerge point.
• Using Combo before enemy interrupts are spent.
• Chasing permanent health into a fight the team cannot reach.
• Casting Scorn away from enemy heroes and receiving the weaker recovery.
• Building only durability while cooldown and access remain unsolved.

Mo & Krill Lore

Maurice and Krill are Tunnel Rats who move illicit goods beneath the Cursed Apple. They are not merely smugglers: they protect the tunnel system and the hidden commerce that depends on it.

Sources And Methodology

Hero type, complexity, starting stats, ability names, and ability descriptions were checked July 21, 2026 against the current Deadlock API asset data. That independent project parses the live game files; it is not Valve.

The meta snapshot comes from Tracklock’s standard hero table. The item package comes from its rolling 58-game Mo & Krill pro sample, and the skill priority comes from completed normal matches on the July 9 patch. Tracklock says it captures a large proportion of matches, not every match. Pick rate, win rate, item frequency, and completed-build win rate answer different questions and must not be treated as interchangeable proof.

Valve’s July 9, 2026 update is the current official patch reference. Deadlock remains in active development, so recheck the live build and patch notes before copying a route into a later version.
