Tip: Ba'al and Unrest

[Dragar]

Owl quill is underpowered, mostly because of the small return for a mage turn, but used early enough can still be worthwhile. Lightless lanterns are useful, in particular because there aren't a lot of good uses for fire gems outside of direct combat use. Skull mentor is the best, certainly, but it costs use of one of the best gem types, so it doesn't see as much play (from what I've seen) as the lanterns.
