Where to hunt in my 20's

[azeth]

I'd stick to soloing the 2 spawn Lake Rathe Aviak at the Arena entrance, or possibly take the light tower (3 spawn) if you can handle it. You can do that safely and for reasonable spell $ up until 24, at which point you ought to consider High Keep, Mistmoore, Uguk for some grouping. Alternatively once you have Cajolling Whispers at 39 you can solo Ogre Guards or Spectres instead of grouping.
