Argent Dawn Reputation Guide (Classic - WotLK)
The Argent Dawn faction is from Classic WoW. It's main hub is Light's Hope Chapel in Eastern Plaguelands. However there are additional hubs in Western Plaguelands for both Horde and Alliance. The easiest way to gain reputation with The Argent Dawn is by running Scholomance or Stratholme.
I recommend that you run Stratholme to kill Baron Rivendare. Baron Rivendare has a chance to drop a very rare mount, Baron Rivendare's Mount. This mount will give you a Feat of Strength Achievement as well as contribute towards the collect 100 mount achievements. Plus it looks amazing and is the only Skeletal Warhorse mount an Alliance player can get!
The Regular mobs in Strath and Scholo will give you around 5-10 rep. The bosses will give you 150-250 reputation. In addition to these two ways to raise your reputation you can also loot Scourgestones. In order to get a Scourgestone you must have your Argent Dawn Commission equipped, then you will start to see the Scourgestones drop from and Scourge mob.
Something to keep in mind is 20 Minion's Scourgestones = 10 Invader Scourgestones and 10 Invader Scourge stones = 1 Corrupter's Scourgestone. Minion Scourgestones drop from regular mobs, Invaders from Elite mobs and Corrupter's from bosses. When turning in any Scourgestone you will gain 50 reputation. In addition you are given a mark which will increase your reputation by 75.
