For something farther off the beaten path, a place I've spent time at and never seen anyone else leveling though still super convenient is the Tizmak caves in The Great Divide, I found the Tizmaks to be an exception to the typical high HP Velious mob.This place is really nice, start outside with a few statics and a pather, work inside when you're comfortable. It's a 2min run to Thurg for everything you might need.

I like both the kunark and velious posts.
