I'm going to be getting my Artifact Pole this week on one of my alts. Everyone is welcome to join.
My plans are for Monday/Wednesday/Friday. This should be plenty of time to obtain it.
Requirements: Be 110. The final quest item won't drop if you're below 110.
Dates: M/W/F after 6pm central
Character: Cetibanks (she has water walk so 1 one zone will be easier)
Preparation 1: If you want to get the pole faster, I suggest you buy the Lures from the AH. If they are to expensive then don't.
Skrog Toenail/Aromatic Murloc Slime*
Rusty Queenfish Brooch
Funky Sea Snail/Salmon Lure*
Swollen Murloc Egg
Moosehorn Hook/Silverscale Minnow*
Ancient Vrykul Ring
Stunned, Angry Shark**
Message in a Beer Bottle/Axefish Lure*
Decayed Whale Blubber/Ravenous Fly*
* If you can purchase, do it, it'll save time.
** can't be purchased from the AH.
Preparation 2: Fly/Goblin Glider Kit/Rocfeather/Glide down to Moroes place just north of Dalaran and catch Mana (there should be raids for this), purchase about 30 Arcane Lures.
