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.

LocationsEdit

Chaos Tunnels entrances

Use the middle south entrance just east of the wizard who teleports player to the Abyss. This is labelled entrance number 2 and goes directly to the giant rock crabs.

StrategyEdit

Giant Rock Crabs are extremely resistant to Melee and Ranged attacks, and thus are only effectively killed using Magic.

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.

RetreatEdit

The Giant Rock Crab is one of few monsters that will retreat from battle when they become critically wounded.

TriviaEdit

  • After the 27 May 2009 update, Giant Rock Crabs dropped Charms in groups of three instead of ten. This hidden update initially angered players, though complaints died down as the rate of charm dropping was also increased.
