Long story short, the Wardens' Armory is a common equipment storage shared between your characters across campaigns and savegames. While it suffers some limitations because of the possibilities offered by the script API, some may still find it quite useful.

As explained in the guide to the Armory available just above, the Armory requires some intervention from outside Dragon Age on the players part. This little tool will spare you the trouble of looking for the lastest Armory export among thousands lines of log, doing most of the job for you.
