For the Relic Reborn quest, for Paladin (Curtana) there are some problems with the quest text and mobs involved. On one portion of the quest, you are required to go kill some beastmen in Southern Thanalan. The quest log text shows that you must kill 8, of 3 different types of beastmen. One of the types listed is Archers, where as you actually need to kill Thaumaturges. The symbol for the quest (little magnifying glass thing) is also above the mages, not the Archers. You get no credit on the quest for killing Archers, but instead again for the mages. When you kill a mage, it says you got credit for killing an Archer.. because that's what the game text log says it should be. I successfully defeated the required mobs including 8 mages, and the quest was complete.
So, you need to correct the text in the quest to reflect the proper mobs, and the text that pops up on the screen when you defeat one of the required mobs.

No other info should be required... It's a quest text problem.
