The Pros and Cons of Using Ruby Bolts Against the Gemstone Crab

September 25, 2026 4 min read

Explore the advantages and disadvantages of using Ruby bolts against the Gemstone Crab in OSRS combat.

Understanding Ruby Bolts (e) in Combat

Ruby bolts (e) are a popular choice among players facing the Gemstone Crab due to their unique properties. Unlike standard bolts, Ruby bolts (e) can trigger a special effect that increases your damage output significantly. This is particularly useful given the crab's near-infinite hitpoints and low defense stats.

Why Choose Ruby Bolts?

  • High Damage Potential: When activated, Ruby bolts (e) calculate damage based on a fixed hitpoint threshold, treating the crab as having only 300 hitpoints. This means you can hit much harder than with regular bolts, especially with the Zaryte crossbow.
  • Efficiency: The ability to hit high numbers quickly can lead to faster gem collection, as you might be one of the top damage dealers. Remember that the top 16 damage dealers get the chance to mine the crab's shell for gems.
  • Passive Experience: If you’re using the Lunar spellbook, casting Magic Imbue can provide some passive Magic experience while you're at it.

However, while Ruby bolts (e) might seem like a no-brainer, they do come with their own set of drawbacks.

The Drawbacks of Ruby Bolts

  • Cost: Ruby bolts (e) are not cheap. They require a considerable investment, and if you're frequently using them, the costs can add up quickly. For players on a budget, this can be a significant concern.
  • Inventory Space: Each bolt takes up an inventory spot, and if you’re planning on running a prolonged session at the Gemstone Crab, you might find yourself running out of space for food or potions.
  • Potential for Waste: If you don’t hit the special effect, you might not be maximizing your damage potential. This can be frustrating, especially when you see others dealing significantly more damage.

To get the most out of your Ruby bolts (e), here are a few strategies.

Tips for Using Ruby Bolts Against the Gemstone Crab

  • Use a Zaryte Crossbow: This weapon pairs excellently with Ruby bolts (e) and has a higher damage output overall. The combination can help you secure those top damage spots more easily.

  • Coordinate with Others: If you’re part of a team, try to synchronize your hits. It’s also beneficial to be aware of when the crab is about to burrow, as this can affect your timing for when to unleash your special attack.

  • Consider Your Gear: Make sure you’re wearing gear that enhances your ranged stats. Opt for items that provide bonuses to damage or accuracy, optimizing your overall performance.

  • Keep an Eye on Your Supplies: While Ruby bolts (e) can be effective, ensure you have enough food and potions to sustain your combat. If you're taking damage while trying to maximize your kills, it can quickly lead to defeat.

Comparing Ruby Bolts to Other Options

While Ruby bolts (e) are a good choice, they’re not the only option available. Let’s see how they stack up against some alternatives.

Amethyst Bolts

  • Pros: Cheaper than Ruby bolts (e) and can still deal decent damage. They don’t have a special effect, but their cost-effectiveness makes them appealing for longer training sessions.
  • Cons: Lower damage potential compared to Ruby bolts (e), especially when factoring in the crab's HP.

Diamond Bolts

  • Pros: Slightly better than Ruby bolts (e) in terms of damage but come at a higher cost. They can also be used to secure your place in the top damage dealers.
  • Cons: Can be pricier to maintain than Ruby bolts (e) if you’re not hitting the special effect consistently.

Final Thoughts

In conclusion, Ruby bolts (e) can be a great addition to your arsenal when tackling the Gemstone Crab. Their high damage potential and ability to help you secure gems make them a worthy investment for many players. However, consider your budget and other equipment options before diving in.
