Black pearl Items are extremely popular with Rogues. Bards and Dual wielding classes also show alot of interest. Enchanted bar of Electrum is gained from level 16 Enchanters if you are not one yourself. I found all my Enchanters Enchant bar spells in Felwithe. Enchant vellium however is in Thurgadin off the great divide (stone next to Nexus in PoK).
My enchanter is from the Stromm server where prices are hideously high, at first i hated it but now i'm reaping the rewards.
