Don’t remember who I stole this from so credit to them, it’s pre rotw, so missing some of the bases the warlock made valuable. Not fully complete but should work as a good starting point. Double check prices but if you’re on NL a lot of the non eth/superior bases listed here aren’t that valuable anymore and you should only bother with eth/sup variants.

Correct me if I'm wrong, but I believe holy shield can no longer spawn on paladin scepters due to it only spawning on them in LoD due to a glitch.
