I recently started playing, just got to Harmondale, cleared the castle and went to Stone City. I'm wondering where to go next, what location will have monsters I will be able to defeat (and quests), because progressing main questline is too difficult right now (Oozes in mines in Bracada Desert are far too strong for me right now). All party members have lvl 6. I would appreciate some suggestions :)

Try your luck in Erathia or the Tularean Forest. Your party should be able to handle some of the stuff there.

Erathia

Spoiler if you want.............................

The City has a fountain that gives 50 Plus Might, a globe that gives Heroism, another globe for Day of the Gods, and a couple other enhancement wells. With that help, Erathia can be cleared of all opponents very early.

Yeah Erathia has some good quests for your level right now :) Check the Harmondale inn for some quests!
