pieces of shield should go for 50-100k each.
50k because bloody once vended hundreds of them for that price, 100k because bloody no longer vends it seems and that 100k is imho an appropriate value for such an item. I happen to farm them too from LOD and yes 100k is a very fair price. Just to be clear, i'm not selling any because i haven't farmed him in quite some time and my stock has been used by my friends.
WAFs are around 60-100k. Most DE personnel seems to have tons of them. Might want to contact Suijin.
hope i helped
