We've datamined a new achievement for WoW's 20th Anniversary Event that reduces the costs of updated Tier 2 sets after one is purchased!
NEW Purchase an updated Tier 2 armor set during the WoW Anniversary celebration.
Reward: Lower the cost of additional Tier 2 armor ensembles.
With all 13 classes receiving updated Tier 2 armor sets during the upcoming 20th Anniversary Event, players will have a lot to collect — and thankfully, some of it is going to be cheaper than expected. This achievement indicates that after purchasing one Tier 2 armor set at full price, all additional Tier 2 ensembles will receive a discount.
While we don't know how steep this discount will be, there are tons of rewards coming to this celebration in patch 11.0.5, so every bit will help.
