Why don't the gauntlets drop spells, official spells for your spell-book. It would be more worth it if you dropped spells. For example, in the great clock gauntlet you could give a spell like Lugs. Lucia or Bernardo Dondi's spells would be cool to get from defeating the boss. It gives a better reward and another use for the characters. Or even just take some of the treasure cards that drop and make them official spells. It would certainly make gauntlets better.
