Try and play the warlock quests like this:

When you complete A quest you can do ONE of the following:

A. Take a talisman as normal

or

B. Take ANY ONE item from the Purchase Deck

or

C. Look at the TOP "X" number of cards in ANY Deck

AND take ANY ONE object/magic object/follower

AND put the remaining cards back on top of the deck in any order (ie spells, adventure, any realms decks etc).

"X" Each quest you complete ADDS 5 cards to your search depth.

Keep quests face up when completed to show your current search depth.

e.g. 1 quest = 5 search depth, 3 quests = 15 search depth.
