Everyone has a plan until they're grabbed by a mole man.

— Krill

Mo & Krill are Heroes in Deadlock. Fighting together, they are a disruptive and mobile pair that can burrow around the battlefield and leave their enemies in ruins. Beginning encounters with Burrow can let Mo & Krill pop out on unsuspecting enemies, attacking them with Scorn to damage and Sand Blast to disarm them. With the support of their team, they can Combo one targeted enemy to pin their target in place while the rest of their allies unleash their attacks.

Members of The Tunnel Rats, Maurice and Krill are smugglers and illicit traders who make the underground of New York their home. Rival gangs that try to exploit these tunnel systems for their own gain will rapidly discover how protective and deadly this pair of smugglers can be.

Mo & Krill can use Scorn and Sand Blast while burrowed.
Mo & Krill can enter Vents while burrowed, if not in combat. However, if Burrow goes on cooldown while inside a Vent, they will be unable to exit until the ability is off cooldown.
Mo & Krill can still be hit by Melee Attacks while burrowed.
Mo & Krill can carry the Soul Urn while burrowed, since it's not affected by Movement Silence. However, they cannot enter vents while carrying it and will still drop it if hit by a melee attack.
Burrow cannot pass through Graves' Grasping Hands.
While burrowed, Mo & Krill cannot be pulled by Abrams' Shoulder Charge and will pass under McGinnis' Spectral Wall.

Sand Blast launches a fast moving cylindrical projectile (similar to Silence Wave) that applies the damage and the effects when it hits enemies.
- Paradox's Time Wall has inconsistent interaction with the ability. If a wall blocks the projectile completely, then Sand Blast gets properly delayed. If, however, at least some part of Sand Blast's projectile is not blocked by a wall, then the whole projectile ignores the wall.

T1 upgrade makes Sand Blast trigger Mystic Burst, which might be undesirable since otherwise the item's damage can only be triggered (and healed off of) by Scorn.

Boon scaling is not applied retroactively to existing stacks.
Upon ability use, Combo keeps momentum, most obviously shown with Majestic Leap.
If either Mo & Krill or the enemy are pulled by a Displacement effect, such as Rescue Beam or Bebop's Grapple Arm, both Mo & Krill and the enemy are displaced together.

Backstory

See Mo & Krill/Lore for more story content.

“

Mo and Krill are members of The Tunnel Rats, a group that help facilitate illicit trade and commerce between the boroughs thanks to a network of underground tunnels. But while most denizens of the New York underworld respect the work The Rats do, every once in a while a gang tries to exploit the tunnel system for personal vendettas...that's when Mo and Krill step in and remind the city what happens to those who disrespect their hospitality.
