Shield of Arrav/Black Arm Gang

Black Arm Gang

Items required: food and a weapon (both optional but recommended).

To join the Black Arm Gang, talk to Charlie the Tramp located near the south entrance of Varrock. Ask him what's down the alley, and he'll tell you that it's the Black Arm Gang's headquarters. Go down the alley and enter the building. Look for a woman named Katrine and talk to her.

Tell her you know about her gang and that you won't give your source. Ask her about what you should do to prove that you're trustworthy, and she will give you a task to join her gang.

Katrine wants you to steal from the Phoenix Gang. She wants two of their crossbows. However, you will need a partner in the Phoenix Gang for this part of the quest. Your partner must give you the Weapon store key they obtained when they joined the Phoenix Gang. Once you have the key, go toward the Phoenix Gang's hideout in the south-east corner of Varrock between the two pubs. Look for a small room directly south of the rune shop with a locked door and a ladder visible inside. When you've found it, use the key with the door and climb up the ladder.

You will have to kill the Weaponsmaster on this floor. If you try to pick up the crossbow without killing the Weaponsmaster first, he will prevent you from doing so. Once he is dead, take two Phoenix crossbows. When you have both of them, go back to Katrine, and she will make you a member of the Black Arm Gang. Go upstairs in the hideout and look for a cupboard, which contains the right half of the Shield of Arrav.

Note: If you are worried about the battle or if you do not want to gain combat experience, you can ask your partner to kill the Weaponsmaster and trade the Phoenix crossbows to you. Have your partner from the Phoenix gang drop-trick the weapon store key while talking to Straven to get a duplicate, and have them give that key to you. Then you can both enter the store room and they can kill the weaponmaster while you get the crossbows.
