So Close... Yet So Far

I have currently spent about ~6-10 hours farming the 3 Silver Knights at Anor Londo for Concords. I have 99 luck in NG+2 at level 210. I have the Symbol of Avarice on, the Crystal Sage's Rapier in off hand, Gold Serpent Ring +1. After using a Rusted Coin I have 474 item discovery. I am 4 Concords away from DMB/Level 3 Darkmoon. For anyone farming these as well, I feel your pain, I have over 70 of each piece of silver armour and shield. Just stay in it!
