AFK Training Alternatives: Comparing Gemstone Crabs to Sand and Ammonite Crabs

October 20, 2026 4 min read

Exploring the practical differences between Gemstone Crabs and traditional training spots for effective AFK training.

Introduction

When it comes to AFK training in OSRS, many players gravitate toward well-known spots like Sand Crabs and Ammonite Crabs. However, the Gemstone Crab, located in the Tlati Rainforest, offers unique advantages that can make it a compelling alternative. This article will break down the key differences between these popular training methods and discuss why incorporating Gemstone Crabs into your routine might be worth considering.

AFK Training: A Quick Overview

AFK training allows players to gain experience while engaging minimally with the game. This is particularly useful for busy players or those who need to multitask. The primary aspects to consider when choosing an AFK training spot are:

  • Experience per hour
  • Accessibility
  • Loot potential
  • Safety from other players

For this comparison, we'll look at Sand Crabs, Ammonite Crabs, and Gemstone Crabs on these factors.

Sand Crabs: The Classic Choice

Sand Crabs have been a staple for new and veteran players alike for years. Here’s what makes them stand out:

  • Hitpoints: Sand Crabs have 60 hitpoints, allowing for a decent amount of combat time before they respawn.
  • Low Defense: With low defensive stats, they are easy targets for players of all levels.
  • Location: They are found on Hosidius beach, accessible via several transportation methods, including the fairy ring.

However, they also come with some downsides:

  • Low Loot: While you can collect some herbs and seeds, the loot is minimal compared to Gemstone Crabs.
  • PvP Risks: Busy locations can lead to unwanted player encounters.

Ammonite Crabs: The Mining Bonus

Ammonite Crabs, located near the Fossil Island, have their own perks:

  • High Hitpoints: With 100 hitpoints, they allow for longer training sessions without interruption.
  • Mining Resource: Killing these crabs gives you a chance to obtain fossils, which can be useful for training Crafting and Prayer.
  • Low Damage Output: They deal minimal damage, making them a safe training option.

Yet, Ammonite Crabs also have some drawbacks:

  • Travel Time: Getting to Fossil Island can be cumbersome, especially for newer players without access to certain quests.
  • Higher Competition: Similar to Sand Crabs, their popularity can lead to crowded spaces.

Gemstone Crabs: A Hidden Gem

Gemstone Crabs provide a unique blend of training benefits that set them apart from Sand and Ammonite Crabs:

  • Shared World Boss: As a shared world boss, Gemstone Crabs have effectively infinite hitpoints and no meaningful defense. This makes for easy, near-AFK combat training.
  • Loot Variety: When defeated, they drop various uncut gems, including opal, sapphire, and even dragonstone, making them an excellent choice for players looking to profit from their training. The top damage dealers can mine the shell for these gems, which can significantly boost profit margins.
  • Low Damage: The crab's attacks deal minimal damage, allowing you to train safely while focusing on other activities.

However, there are a few considerations:

  • Travel Requirements: Players need to complete the quest "Children of the Sun" to access Varlamore and the crabs. Once accessed, the quetzal transport system simplifies travel.
  • Timing: The crabs rotate between three mining locations every ten minutes, so timing your moves is key to avoid missing out on loot.

Comparing Experience Rates

While specific experience rates can vary based on gear and combat level, here’s a general breakdown:

  • Sand Crabs: ~25k to 30k Combat XP per hour with minimal effort.
  • Ammonite Crabs: ~40k to 50k Combat XP per hour, boosted by the potential 50% bonus from the mining resource.
  • Gemstone Crabs: Potentially 50k+ XP per hour, especially when combined with passive Magic experience from using Magic Imbue. This can enhance your overall gains from training.

Conclusion: Which Crab for You?

Choosing between Sand Crabs, Ammonite Crabs, and Gemstone Crabs ultimately depends on your goals and playstyle. If you're looking for a traditional training spot with straightforward mechanics, Sand Crabs are solid. Ammonite Crabs are great for those who want to combine combat with mining.

But if you're after profitability and unique training mechanics, Gemstone Crabs could be the best option. Their potential for gem drops and the ease of low-damage combat make them suitable for both new and seasoned players. Plus, the AFK benefits are hard to overlook.
