The Avatar Of Below that gives the quest wanders around a fairly large area. He's a huge NPC, which makes him easy to spot. Find him east of the North Qeynos bridge in the fields and as far out as the guard tower near ( -328, -14, 67 ) /waypoint -328, -14, 67.
Good characters may ask a guard at the bridge for "Avatar" and get a waypoint to his location.
Very low level characters may not be able to complete this alone. The gnolls in this Blackburrow are level 11+ and some are ^^^.
Obtain some beer from the Blackburrow brewery ( 21, -40, 61 ) /waypoint 21, -40, 61.
Note: Getting to the brewery requires a swim under water. Swim under at cave entrance ( -1018, -42, 1178 ) /waypoint -1018, -42, 1178 and go thru door at ( -1106, -34, 1066 ) /waypoint -1106, -34, 1066. Follow the tunnel and just as it opens up you see a stack of brown kegs stacked 3 high. Right click the top keg for update.
Find a Gigglegibber Ginger Ale by zoning into the Bar of Brell and talking to Gergy Gigglegibber. He has the ginger but needs you to find him some Ale.
Speak to Tumpy Irontoe as he wanders along the road from about ( -253, 154, -419 ) /waypoint -253, 154, -419 to about ( 295, 150, -466 ) /waypoint 295, 150, -466. To obtain his current location, you can ask for directions from a guard. Tumpy wants you to streak nekkid across the docks in Butcherblock Mountains! He gives you Liquid Courage (it's in your inventory)
Stand on the Butcherblock Docks ( 723, 24, 577 ) /waypoint 723.16, 24.00, 576.64. Use the Liquid Courage When you take a drink you are nekkid and run automatically.
After you've finished streaking, talk to Tumpy on the docks where he appears (not back out near Kaladim!) to get the update.
