So I noticed in the 3.5 patch notes, under completion rewards it says.
Upon completing Dun Scaith, players can also earn a separate reward once per week. This reward can be exchanged with Bertana in Idyllshire (X:5.8 Y:5.2) for items used to enhance equipment purchased with Allagan tomestones of lore.
It says it's for items used to enhance equipment purchased with lore but is it supposed to say scripture since that's what the high end gear is?
