This guide is suitable for current RuneScape and Old School.
Talk to Achietties who can be found south of Burthrope outside the Heroes' Guild.
To get the firebird feather, you must first get ice gloves, as the feather is too hot to hold with anything else. To get these gloves you must kill the level 111 Ice Queen, who despite the high level, is actually quite weak.
Go to the northern side of the White Wolf Mountain where you will find a rockslide.
For this part, you will need the help of a friend in an opposing Varrock gang to you.
Phoenix Gang Members
Talk to Stravan and ask him about the armband. He will tell you that to prove yourself worthy, you must steal Scarface Pete's Candlesticks.
Go to Brimhaven, on Karamja, and go to the Shrimp and Parrot Inn. Speak to Alfonso the waiter. Give him the password 'Gherkin' , and he will tell you to go around the back.
Talk to the Chef, and also give him the password. He will tell you to check out the hidden door at the side of the building.
Go back into the Inn, and get your Black Arm Gang friend to give you the miscellenious key. Go back through the Inn, and unlock the door into the back of the mansion. Wait for your friend to lure Grip into the room, and range him through the slot in the wall. Once he is dead, your friend will take the keys and unlock the chest with the candlesticks in them.
Take a candlestick from him, and travel to Varrock and give it to Stravan. He will tell you he is in a good mood, and give you the armband.
Black Arm Gang Members
Go to the gang base in Varrock and talk to Katrina. She will tell you that to get the armband, you will need to prove yourself worthy by stealing one of Scarface Pete's Candlesticks.
Go to the house near the gate in Brimhaven, on Karamja, and give them the password '4 leaf clover'. They will give you an ID paper, and tell you what you need to do to get into the mansion.
You will now need to wear full black armour (a black full helm, a black platebody, and black platelegs). These can be bought at the Champions Guild store or through the Grand Exchange.
Once you have them, go back to Brimhaven, and go into the mansion next to the Shrimp and Parrot Inn. You will have to show Garv your ID card. Once in, talk to Grip and ask for something to do. He will give you a miscellaneous key.
Go back outside and give your Phoenix Gang friend the key. He will then get ready for the next stage.
Go back inside and walk into the room with lots of crates and 2 chests. Open the cupboard and choose one of the options. Grip will come running into the room. Your friend can now range him. Once he is dead, take his keyring, and walk into the room next door. Unlock the chest and take out the 2 candlesticks. Go back outside and give one to your friend.
Go back to Varrock and exchange the candlestick for the Master Theives Armband.
Cooked Lava Eel
Go to Port Sarim and speak to the owner of the fishing shop about Lava Eels. He will give you some Blamish Snail Slime. Use a Clean Harralander on a vial of water to get an unfinished potion. Use the unfinished potion on the Slime to get Blamish Oil. Use this on a fishing rod to get an oily rod.
Get an Anti-Dragonfire Shield on, and bring some food. Enter into Taverly dungeon, and walk around the outside, through the room with the Magic Axes, south past the Chaos Dwarfs, and into a large dungeon full of Black Knights. Search around until you find a jail. Kill the jailer, and open the cell with the key he drops. Talk to the prisoner, and ask if there is anything you can explore. He will give you a dusty key.
Take the key, and go back to the area with the Chaos Dwarfs. Go across the bridges and unlock the gate by the Lesser Demons. Run past the Blue Dragons until you come to a location with Baby Blue Dragons and a lava river. Fish at a fishing spot and wait until you catch a few lava eel, just incase you burn the first. The baby dragons shouldn't do much harm to you, even without armour.
Either go back through the caves or teleport out, go to a range, and cook the eel.
Now that you have all the items, simply go back to the Heroes Guild and present the items to Achietties.
Congratulations! Quest Complete!
