Seems I've been writing quite a bit about the Argent Tournament across several posts so I thought it was time to put an index post together...
The Argent Tournament I - Guide for Aspirants.
The Argent Tournament II - Guide for Valiants.
The Argent Tournament III - Guide for Champions.
The Argent Tournament Quest Chain.
And there you have it.
Ooo and while we're here you really have to read Flame Shock's tip for Quickest City rep with Argent Tournament. I'm not going to re-hash it here, go read it, it is very well written.
