Deadlock Mo & Krill Guide: Burrow Build & Lockdown (2026)

Last updated: June 3, 2026

Mo & Krill is the tunnelling tag-team that makes the enemy carry disappear — burrow in, lock a target in place, and chew through them while shrugging off everything in return. He's tanky, forgiving and one of the best heroes to learn aggressive play on. This guide uses the current data deadlock.io build sites pull from.

Quick answer: Mo & Krill is a tanky disruptor: dive with Burrow, disarm the enemy carry with Sand Blast, sustain with Scorn, and grab-and-stun a single target with the Combo ultimate — which permanently grows your health on kills.

His abilities

Ability	What it does
Scorn	An AoE pulse that damages enemies and heals you based on damage dealt. Your sustain and last-hit tool.
Burrow	Dig underground with big armor and speed, then erupt for damage and a knock-up. Your engage.
Sand Blast	A cone that disarms enemies (they can't shoot) and deals damage. A huge skirmish swing.
Combo (ult)	Grab and hold a single target, stunning and damaging them — and gain permanent max health if they die.

🎮 Dota 2 players: he's Sand King meets Pudge — a burrow engage and cone disrupt, with a single-target "you are deleted" ult whose permanent-HP-on-kill is pure Flesh Heap.

Build & leveling

• Early: Mystic Shot, Mystic Vulnerability, Melee Lifesteal
• Core: Alchemical Fire, Greater Expansion (bigger Burrow/Scorn), Superior Cooldown
• Late: Colossus, Spiritual Overflow, Unstoppable

Ability order: max Scorn first, Burrow second, one early point in Sand Blast; take Combo at every breakpoint.

Tips

• Don't waste Combo on a tank — save it to delete a squishy and bank the permanent HP.
• Burrow is also an armor/escape button, not just engage.
• Land Sand Blast on the enemy carry before they can shoot back.

Mo & Krill sits around A/B-tier (~51% WR) in June 2026 and is a superb, forgiving beginner pick. Builds shift per patch.
