Hi, i have completed the knights of the nine main quest and got the weapons and all the armor, but when i go to equip it, it says something along the lines of walk the pilgrimage or somethin. I cant remember what this is as it was a long time ago when i did it, can you help me out? Thanks.

it means that since you got the armour/weapon you have done bad things - (murder,theft etc) and are no longer deemed fit to wear the armour.

you need to re-do the pilgrimage (prey at the wayshrines)

Ok, thanks, do i just do them straight away or do i have to speak to someone?

Just do it straight away. It will purge your infamy to zero. Then you can equip the relics again. If you gain a point of infamy again, you'll get a warning. If you gain two points of infamy, you'll be unable to wear the relics until you again do the pilgrimmage. :foodndrink:

I had this happen to a paladin character once. There I was doing the main quest and attacking everything in sight. One of the strikes must have caught a brother of Weynon Priory.
The next thing I know I lost the Boots of Kynareth. Lovely....that is the thanks I get for helping....

Unless you are role playing save yourself the effort and reload a save.
