Guild Wars 2

According to the description, the Mistward Warboots collections should be unlocked after fully training the Corruption traitline. I had the other 4 pieces collection unlocked just not the warboots.

I tomed my character to lvl 80 in Black Citadel after the tutorial. Trained all traits in one shot except Herald.

I think I read another similar topic but with different piece of armor.
Is there already a solution?

There was at some point a “Specialization Achievement Repair” NPC in Heart of the Mists you could talk to to get this fixed. Take a look there first.

I think the NPC may have been removed though. Based on this Reddit thread, if you send in a Support Ticket, they’ll fix it for you.

Fixed after sending in support ticket.
