Some more info: I hit this quest dedicatedly to get the linked 'Surface Assault' quest.
First 10 times: the choices were Varsoon guards and clat crawlers.
Second 10 times: Choices were the Varsoon disciples, clay guardians, servants of Varsoon, enchanted clays.
Third 10 times (in progress): Choices were forge stokers, claychanters, and forge sparks. Note, the forge stokers, though only popping one at a time with the smith, may /seem/ longer, the stoker will reset if you flee the smith. So far, my experience with the clatchanters is that they will not reset. As of this writing, I'm waiting on my first sparks pop.
The opening dialogue changes at each stage, though the resultant quest is the same. (Stage 3 bumps to a minimum 1g reward.) Yesterday, I /only/ did this quest, and my eq2players.com quest total went up by two, so you get a new 'credit' each time the stage changes.
