There is some items like Proof of a Concord Kept
http://darksouls3.wiki.fextralife.co...a+Concord+Kept
That has two ways of getting them....
1) Reward for defeating invaders when defending a Way of Blue member as a Blue Sentinel or Blade of Darkmoon.
2) Rare drop from Silver Knights in Anor Londo and Irithyll of the Boreal Valley.
The chance of getting summoned for step 1) is super small at lease on Ps4. I even started over and didn't get summoned once. So that leaves me with step 2. The drop chance is soooo low I could be grinding for 10 hours easy just to get all 30 I need to rank up in Blades of the Darkmoon.
This is not the only item u may have to grind for that way as well. I just want the drop rate increased and ill be happy. Would love to platinum this game and that is whatz standing in my way.
I wish its trophy's was as simple as Bloodbornes but o well.
Edit: To add the reason you have to do this for trophy's is so you get all the rings and spells for those two trophy's.
