The spawn time on this jug is 10 minutes. Enough time after clearing for two people to grab it, but not quite enough for a third. Unfortunate for us since we were lucky to clear it the first time, but Stonemight Chieftain Swiftear spawned across from the jug inside the house on the respawn and I don't think our tank has 8k hp for the dagger spell.
This can be attained solo if ya sneaky ranger. It is in the little hut that named Gobby is in. If come from the back and to the right side invis, crawl in the window and use /open command and immediately insta-camo back up. Then use /loot command and re-invis again while backing away.
Fun to find tricks to doing these quests on your own as much as possible.
make sure there are no trackers near you. trackers can see through your invis - found out the hards way. 700 hits don't make for a good time with a 56 necro.
