Hey there! im hunting for all the loot! to maximize my club membership i already did all the mauv manticores from 14-23 what a great ride it was! before that no guaranteed loot right? Other than that, there are the paid content missions (that give an epic item, that upgrades my membership slot to a good item, right?) anything else im missing?
A few lower level adventures also had guaranteed loot, but I'm sure you've already finished them (the best was Melvelous). The only one you're probably missing is Caverns of Chaos. You can also look for yourself in the adventure database under the "First Time Loot" columns.
Yeah, completing quests is a good way of getting value from your club membership. You can amass quite a collection of items just by doing "No party deaths" and other easier quests. In addition, club members usually get an extra epic or higher quality item when they complete Treasure Hunts for the first time. And don't forget the Loot Fairy!
