Reward List
The end reward of the whole chain given by NPC Tessa Aster after completing all of above quests (called The Taken in your quest journal) is a mix of items that can be pulled from one of the optional chests in the chain, as well as several items gainable solely from here, and 1-2 items of random loot. So a player has the chance to pull an item directly in one of the quests or get it at the end of the chain. The random items are BtA.

Note that you can talk to Tessa Aster and run the chain again - in any order, as long as you do all four quests - for another reward. Currently the reset option is broken, abandon all quests from the pack incomplete and complete to get the quest again

Following is the list of items that can only be acquired by completing the chain.
