The Rare Goods vendor was a special temporarily established store in dome city next to Hawk's. It was introduced in patch 1.42 in May 2011. Later it was removed again in patch 1.5 in September 2011 because of players using AvA exploits.
The Rare Goods vendor sold rare dyes, flair, as well as rare items and pets. The rare Good vendor's offerings may changed from day to day.
