PART ONE OF TWO, SEE COMMENTS FOR PART TWO

For Horde Loremaster:

All soloed on my alt 110 ilvl 934 Guardian Druid. If you’re deciding to do loremaster later in the game like me and you’re starting the zone fresh, I highly suggest doing it on a druid because you can kill and instant fly off, makes things go by so much faster.

All I did was follow around the large bold exclamation point on the map. Sometimes the quests are mixed and it makes you run around back and forth, but so be it. This is still minimum list of quests to do, everything else is a side quest.

*Note, easiest way to help you find the cave you need to get back to to turn in, there’s always big yellow flower things w/a purple base, waving in the water right in front of the entrance
