Hi all, I've been farming rare spawns on the Timeless Island for the past couple of days and have found a trick to summoning Zhu-Gon that does not require killing any skunky brew alementals. This can help save you the time of nuking down ten 1.3million HP adds or possibly solo summon the rare mob if you are Leveling from 85 to 90 on Timeless Isle - 10-25M xp per hour unrested- solo (Leveling from 85 to 90 on Timeless Isle - 10-25M xp per hour - solo). There are scattered around the spawning point for Zhu-Gon multiple skunked brew barrels that can be easily found and destroyed (they have 19K HP) by tab-targetting when you are standing in the center of the hill. As the barrels do not show up on standard unit frames, they may be hard to spot under normal circumstances but can easily be dispatched by cycling through available nearby targets. Each skunked barrel releases the equivalent of one add from the event, meaning you have to destroy ten of them to spawn Zhu-Gon.
