Giant Roc

The Giant Roc is a large avian monster encountered during the quest My Arm's Big Adventure.

It can be fought in the Nightmare Zone after the quest is complete.

Strategy
It uses both Melee and Ranged attacks, which hit up to 14 and 20 hitpoints respectively. Players are highly recommended to activate the prayer Protect from Missiles when fighting this creature. My Arm will also attack the bird, but his attacks only tend to hit 1 to 3, so the player should not rely on this. Players should beware, as this monster can easily kill those who come unprepared. A one-click teleport is highly recommended.

During battle, the Giant Roc will frequently buffet the player with its wings, knocking them backwards and damaging and stunning them for a short time. This can be countered by standing against a rock or wall, but the attack will still stun. Although the Roc has high magic defence, its magic level is 1, meaning that it is still possible to hit it hard with spells like Iban blast.

Players can usually only land a few hits on the Roc before it blows them back, making it fairly hard to fight. If players do not wish to melee the Roc up close, then they can try ranging the Roc with their backs to the wall or behind the farming patch.

The Giant Roc will destroy a dwarf multicannon if a player uses one.

There is a safepot for mages and rangers on the far end of the mountainside, where the ladder is. By positioning yourself correctly, the Roc's massive size will make it unable to pass the torch that is between it and the ladder, meaning that it cannot come close enough to melee you. Combine this with protect from missiles and the only thing you have to worry about is the Roc's buffeting wings, making this fight not nearly as difficult as usual.

Pure/Low defence/No protection prayers tactic:

Hide yourself behind the goutweed to protect yourself from the Giant Roc's melee attack. Similarly, the small rocky outcrop next to the goutweed is a total safezone if you need to heal etc. The Roc's ranged attack is dodgeable, but requires a good rhythm which is messed up every time the Roc pushes you around.

Just keep strafing forwards and backwards every time in between the ranged attacks (with run on) and shoot twice in between strafes with a shortbow, or cast one spell. This will make the Roc's rocks fall behind you, which makes you not take any damage whatsover.

The buffeting wings will still damage you however, so remember to eat whenever necessary (best to eat while stunned since you can't move anyway).

Trivia

 * The Giant Roc is the RuneScape counterpart to the legendary Persian bird, the Roc. The Persian Roc was said to be able to carry elephants off into the sky, only to drop and eat them later.
 * The Roc has a small chance to drop a long bone either during the quest or when facing it later in the Nightmare Zone.
