Guild Wars 2

Does anyone know which missions reward you with the personal story specific armor? I believe it’s in the 30-60 range but I’m not 100% sure. If anyone knows it would be greatly appreciated.

For reference, this is the set I’m looking for:

It’s the Stalwart armor set, but that’s PvP only: http://wiki.guildwars2.com/wiki/PvP_Stalwart_armor

The other way is, like you mentioned, obtaining it from Personal Story rewards. But I don’t know which quests do give what piece of armor. Guess you’ll have to preview all options before selecting a reward to be sure.
