Brell Serilis Symbol Quest

[karkaroth]

I know the wiki says we cant do the last part but i'm stuck getting even the first part from him. The wiki tells me to say to him 'I will help you find and slay the goblins' as the final dialogue with him but this does nothing for me. Is this intentional can we not do the first part or is the wiki wrong.

While were on the topic are most quests broken here should I avoid any npc quests Iv tried some of the turn in quests they seem to work just curious thanks.
