There are relatively few quests in Sadri Malath. However, any you do find are generally worth doing.
The only faction quests I am aware of are Cercivan Wings and Mountian Panda Paws. The wings sell for a little over a plat to a merchant. The quest NPC will give you a pp and some high gold, close to 2 pp on occasion. I have not yet turned in any paws. This is a more recent quest.
My wizard is still in the opening stages of Art Master Tergon's quest. I do not play him enough, working on Mogger as I am.
Paladins and Shaman (shaman is both plural and singular) have no class quests.
I do not recall one for the warriors before I abondoned mine in favor of the paladin. The Taldorian kick animation is bad.
My cleric is created, but only at level 1. I have no idea if clerics have a quest.
There was a quest in the bar down by the beach for a root spell, but my wizard has yet to relocate it after my shaman found it months ago.
Not sure if I recall any others.
