Cannith Crafting/BtA base items

Quest chain reward lists

 * The Lost Seekers - anything, notably one type of rare material weapon or shield seems to be always included on this list
 * Catacombs

 * The Sharn Syndicate
 * Tangleroot Gorge
 * Phiarlan Carnival
 * Sentinels of Stormreach - every third reward list only

 * Ruins of Threnal
 * Reign of Madness - always a ring included

Single quest/raid reward lists

 * Archbishop's Daughter - anything
 * The Chronoscope - weapons, clothing and jewelry
 * The Sharn Syndicate quests are the easiest place to get items, since each quest is rather short and easy to farm, and gives a choice of several BTA items, rather than having to go through a whole chain - at the end of which you'll likely want to get a named item. However, you won't get a belt or helmet/hat from this chain.
 * Stand Your Ground - cloaks, gloves, rings and necklaces
 * The Bookbinder Rescue - boots, bracers and goggles
 * Dirty Laundry - armor and shields
 * Repossession - armor and shields
 * Come Out and Slay - weapons
