Solo:

1) As I'm sure you've heard, treants in South Karanas give obscene amount of
cash plus fast exp. But it's always camped and bad faction hits with Queynos
Guards and druids/treants in general.
2) The Hermit (unkept druid) in SK also give good exp plus the occasional FS
weapon, that too is often camped. GOOD faction with druids, bad with Unkept
ones.

Grouping:

1) Stone skeleton tower in Lake Rathe. The tower is situated close to the
Rathe Mountain zone. You will need to swim to it and it's a double spawn of
a mage (level 25) in skeleton form and his pet. Get a ranger and/or a druid
to harmony.
2) Icy orcs at Everfrost. 5 spawns plus a nasty caster Orc named Redwind.
Again harmony works wonders and requires a full balanced group.
3) My favorite, Estate of Unrest. Group must consist of at least one cleric
and preferably one person who can SOW. Camp the Hand room for fast exp and
easy escape route, Magi or Bar room for fast spawns, or Tower for the BS
Tunic! One word of warning, keep your pet under a tight leash here as he can
pull massive trains back to you.
