I write about Mad King’s Breach from hours of runs and dozens of tests; I’m a woman who’s played endgame since 2020 and I’ll be direct: this dungeon separates casual gear sellers from serious grinders. If you want reliable rewards, you have to plan for floors, not just hope for luck.
🏰 Quick Overview
Mad King’s Breach opens at level 60 and sits at the top of Diablo Immortal’s dungeon ladder. It resets weekly (usually on Tuesdays, server time). You face multiple floors with escalating enemy HP and damage; higher floors give better loot but demand higher Combat Rating. You can run solo or with a team — grouping becomes essential past floor 25.
💎 Loot and How It Scales
The Breach rewards scale with the highest floor you clear. Expect more Legendary Gems and set drops the higher you go. Why push floors? Better floors increase the chance for 5-star gems and rarer set rolls. That’s the math behind the grind.
| Floors | Common Rewards | Gem Stars |
|---|---|---|
| 1–10 | Basic legendaries, scraps | 1–2 |
| 11–25 | Stronger set pieces | 2–3 |
| 26–50 | High-tier gems, elite sets | 3–4 |
| 51+ | Top-tier drops, rare cosmetics | 4–5 |
Note: you won’t magically get 5-star gems on floor 26. It’s a probability curve; expect many runs.
⚔️ Best Builds (practical picks)
I’ve noticed these builds clear the breach most consistently. You’ll see me prefer safety over flashy damage because one wipe ruins an hour of progress — honestly.
- Necromancer (Summoner): steady clears, minions absorb damage.
- Demon Hunter (Multishot): excels at ranged group damage.
- Barbarian (Whirlwind): strong sustain and mobility in tight rooms.
// Sample Necromancer priority (my lab-tested order)
Army of the Dead = max
Command Skeletons = max
Bone Spear = 8+
Corpse Lance = 6+
Legendary gem order matters. I prioritize survivability gems early, then swap for damage once my clear is stable. Why? You keep more runs going and that increases drop volume — simple math.
🎯 Combat Tips and Rhythm
Positioning beats raw stats when damage gets spiky. Create chokepoints, kite elites, and save your ultimates for bosses. Question: why spend potions early and die later? Don’t. Save them for clutch moments.
- Scout and pre-pull — don’t rush into groups blindly.
- Keep a cooldown rotation in mind (mental timers work better than notes).
- Plan escape routes before fights.
Resource management is crucial on long runs. Use low-cooldown skills on trash. Save high-impact tools for bosses. This tactic keeps your average clear time down and your success rate up.
📊 Scaling, Time, and Where to Stop
The jump in difficulty is steep after floor 25. Expect to need roughly 500–1,000 Combat Rating per decade of floors higher. Push too far and you waste time — that’s a hard lesson many ignore (including me, once). My practical rule: stop 2 floors above your steady clear range; pushing 5+ is usually inefficient.
| CR | Floor Range | Usual Clear Time |
|---|---|---|
| 3,000–4,000 | 1–15 | 40–60 min |
| 4,000–5,500 | 16–25 | 50–80 min |
| 5,500–7,000 | 26–35 | 80–110 min |
| 7,000+ | 36+ | 110+ min |
🛡️ Gear Priorities
Gear choices depend on class and build. Here’s the short version: maximize your primary stat, finish set bonuses, then slot gems. Why that order? The set bonus often adds multiplicative effects that outpace single-item upgrades.
- Tanks: high vitality, damage reduction, life-on-hit.
- Ranged: crit chance/damage, mobility rolls.
- Hybrid: mix minion power and personal defenses.
Defensive targets: at least 30% total damage reduction and a comfortable life pool for your expected floor (life numbers vary; don’t fixate on a single threshold). There are exceptions depending on your build.
Advanced Notes & Controversies
Here’s the funny part: many players blame bad RNG, but I’ve found poor route planning and bad resource timing cost more runs than unlucky drops. Controversial? Maybe — but you can test it yourself.
“Push smart, not harder.” — my shorthand for efficient farming.
Surprising insight: sometimes lowering your Combat Rating slightly (by using temporary lower-stat gear) helps you learn boss mechanics because fights go longer and patterns reveal themselves. It sounds backwards, but it works for training runs (try it on a Tuesday practice session).
Between us, the game leans toward time investment. Some say it’s pay-to-win — I’ll admit the season pass speeds progression, but skill and planning still matter. There are exceptions for whales who skip grind, sure.
Final Practical Checklist
- Know your comfortable clear floor and stop 2 floors above it.
- Prioritize set completion before minor stat tweaks.
- Save ultimates for boss phases and potions for clutch moments.
- Run with a consistent group when attempting high floors.
One last tip: I tested a stretch of runs on 2025-06-01 and kept a log — consistency beats flashy pushes. Keep experimenting, and don’t be afraid to change builds mid-week if a floor repeatedly blocks you. Okay, that sounded preachy — but it’s true!
Good luck out there. Try a calm run today — you’ll learn more in three intentional clears than in twenty rushed ones.
