Hello, my name is Suvvri and I'm here to help you with farming the Proofs of a Concord Kept.
I see that alot of people have problems farming it and are spending MANY HOURS doing it where it took me only like 2 hours to do it.

For it to be the most effective you will need few items:
-Crystal Sage's Rapier +50 item discovery
-Symbol of Avarice +100 item discovery
-Covetous Gold Serpent Ring +50 / +75 / +100 item discovery
-Bunch of rusted coins +50 item discovery for 1 minute

These are the MOST important items but there is one optional ring you might also consider getting and its the skull ring. Why? It lets you aggro the silver knight wearing spear earlier so you don't have to run up to him AND he you can keep more distance to the second knight (we don't want to fight them 2v1).

The most optimal build would be something like 60 int sorcerer with CSS which lets you 2 shot the knights. It's the fastest way to kill them. I did it with quality build using carthus curved sword and dark sword (r1 spam for the win). I tried using my profaned greatsword but i feel that when you miss a hit with it you can have a big problem since you will be lacking stamina to finish the knight off.
Ideally you should reset your stats, get your main damage stats to the softcap (dex/str/luck40 and faith/int 60) and dump the rest of the points into luck for even more item discovery.
Of course by doing it you will be dying by one hit but its your choice. I actually didn't do it but if you are confident about your dodging skills and want to farm ASAP you could do it.

So you have your build, your weapon, your items what now?
You go to Anor Londo bonfire. You equip the ring(s), sage rapier, mimic head, use rusted coin and kill the two knights. Yes two not three since killing all 3 of them will take much longer and it's not worth it when you want the best kill/min ratio.
Every time you sit at the bonfire after killing the knights you use coin. For me (ng+3) the item discovery from the coin was dissapearing after killing 2 knights, sitting down and then killing one more so the 4th knight was actually killed with less item discovery which is not optimal.
For best restults you should use the coin when you are already on the stairs shortly before the spear knight aggros to you. It will make him come to you when you slowwalk while using the coin so again- you spare a little bit tiny time which adds up.
Here is a video how I did it. Its farming the last 2 proofs i need.

Now I bet you are asking yourself- why did this guy shut down dark souls and change his armour?!
This is the point where my guide starts to "shine". This is the point that makes you getting the proofs much faster than some people that were farming it for 8 hours+ and were getting like one proof in hour.
After some "research" (wiki fextralife) I found out that people get much better results at farming those items when they restart the game and also change their equipment every time they get the proof. And you can clearly see it here- I've got 2 proofs in about 5-6 minutes. And it wasn't just one time event! I've farmed all the 20 proofs that I have in my inventory in about 2 hours.

So that's it girls and guys. I hope my guide helps you. If you have any questions you can add me on steam or just write comment down below. Have a nice time farming and don't forget- PRAISE THE MOON.
