FAQ

Is NMZ or Slayer better for combat training?

NMZ is better for pure combat XP at 90-130K per hour, while Slayer is better for profit at 500K-1M per hour from 85+ Slayer. Most players should combine both, AFK training at NMZ and doing Slayer when actively playing.

How much combat XP per hour does Nightmare Zone give?

NMZ gives 90-110K XP per hour AFK and 110-130K active with melee. Using Dharoks at 1 HP reaches 130-160K per hour, making it the fastest pure combat XP method in the comparison.

Does Nightmare Zone give Slayer XP?

No. NMZ provides zero Slayer XP because you fight quest bosses rather than assigned Slayer monsters. If you need Slayer levels for diaries or boss unlocks, you must train Slayer separately.

Which is more AFK, NMZ or Slayer?

NMZ is far more AFK, letting you train for 15-20 minutes unattended, while Slayer requires frequent clicks and attention. Slayer does have some semi-AFK tasks such as Gargoyles and Kraken.

What Slayer level do you need for good profit?

Slayer becomes profitable around level 75, and from 85+ you can earn 300K-800K per hour. At 90-99 Slayer with boss tasks, profit can reach 1-3M per hour depending on the boss.

How long does it take to max combat in NMZ?

Training all three melee stats to 99 at NMZ takes roughly 300 hours total, about 100 hours each. Doing it purely through Slayer takes 600+ hours, which is why the hybrid approach is recommended.

Conclusion

The Verdict: It depends on your goals, but the hybrid approach is best for most players.

Simple Recommendation:

1. AFK NMZ when you can't actively play (work, mobile, studying)
2. Active Slayer when you're focused gaming (profit + variety)
3. Result: Fast combat gains + high Slayer + massive bank

Pure XP: NMZ wins (90-130K/hr) Pure Profit: Slayer wins (500K-1M+/hr at 85+) Best Account Development: Slayer wins Most AFK: NMZ wins by a mile

NMZ is a tool for efficient XP. Slayer is a complete gameplay experience that develops your account while making money. Use both strategically based on your available attention and goals!
