•"Heavy rock!" (when disguised as a boulder)
Giant rock crabs are massive versions of the weaker Rock crab. They lie in wait for prey, disguised as large boulders. When approached, they attack, unless they have become tolerant, in which case they remain as "boulders" - attempting to target them gives the message "Invalid target."
Giant Rock Crabs are good droppers of charms, as they drop 3 of them at a time. They also drop various black equipment (platebody and claws), worth a decent sum of coins. They are the only droppers of rock-shell parts, which are needed to create Rock-shell armour.
- In the Waterbirth Island Dungeon.
- In the Chaos Tunnels (the middle south rift just east of Mage of Zamorak leads directly to them).
A notably effective and economic way to kill Giant Rock Crabs is the Black Salamander, or the Polypore Staff. The Black Salamander's magic attack, and the Polypore staff's attack acts as a normal magic attack and takes advantage of their lower magic defence. Their magic defence is so low you can utilise high level defensive armour without losing much accuracy.
In the Chaos Tunnels, they will eventually lose aggression. When they do, just leave the cave via the rope exit. Then just go straight back down the crevice.
They are most vulnerable to fire-based spells.
Mage Gear is as follows:
- Helmet: Farseer helmet > Infinity > Ahrim's > Dagon'hai > Mystic/Sacred clay
- Necklace: Stream necklace > Amulet of fury > Amulet of glory > Amulet of magic/Amulet of power
- Cape: God cape > Soul war cape > Ardougne cloak (4/3>2) > Obsidian cape, Cape of Accomplishment,
- Body: Ahrim's > Infinity > Dagon'hai > Mystic/Sacred clay
- Legs: Ahrim's > Infinity > Dagon'hai > Mystic/Sacred clay
- Weapon Slot: Polypore Staff, Elemental staff or a 'Magic damage'-increasing staff
- Shield: God book (Unholy>Ancient>Balance) or Broodoo Shield > Mage's book > Arcane spirit shield
- Gloves: Barrows gloves > Rune gloves > Lunar gloves > Regen bracelet
- Boots: Infinity > Wizard's > Mystic > Lunar > Swanky
- Ring: Seers' ring (i) > Tokkul-Zo > Beacon ring > Ring of Wealth
If you are using ice burst or barrage the arcane stream necklace is not as important here because magic damage boost adds only to the target you click on. The other 8 targets do not receive the damage boost from it or your staff, so you would be better off using a necklace with a prayer bonus.
If using burst or barrage spells the Staff of light is recommended despite the lower mage bonus (in comparison to Master wand, or Chaotic staff) given the fact that it gives free casts; when used in conjunction with Battle Robes, it has a 50% chance of saving runes when casting. Even when this effect doesn't activate, the Battle Robes themselves have a chance to save runes, effectively adding up to a 60% chance of saving runes. The Battle robes will, however, only last for 6 hours of combat after which they will need to be recharged (270 tokens).
Provided you are going to be bursting, a Tome of frost is recommended above items that provide a higher magic bonus. This is because rock lobsters have fairly low magic defence (thus the difference in offensive magic bonus is negligible), while the tome saves an inventory space and the need for Water runes.
The Giant Rock Crab is one of few monsters in RuneScape that will retreat from battle when they become critically wounded. One way to avoid this (in the southern room in the chaos tunnels) is to kill the eastern one first (using the safespot in the picture above). Then when picking up the drop from them you will have likely alerted a few other giant rock crabs. Go back to the safespot and two should follow you there, from there kill them. While you're killing them the one you first killed should spawn but not attack (unless you go beside it). Because he spawns the other two can't get out and are trapped, so they cannot retreat. After killing the first one, don't pick up the drop and proceed to kill the second one. This means that you will not alert the one that spawned and you will have another retreat free kill. This may be repeated indefinitely in this fashion.
