A friend of mine is trying to get the rez stick from Old Man Mackenzie. Can any one remember what you need to do to be able to see all of the items?
You have to beat the vox raid to see it and the naggy raid to see others. I forget what was needed to unlock those raids.
In order to flag for those raids, you need to have a certain number of raid clears from I think SoF to UF. A quick run through Crystallos should easily flag them.
