I have my doubts about the Alter of Skulls as I haven't managed to make it work but once so far. The title mentions Malacoda but there have been about 2 matches so far I haven't cast him, preferring to focus on my skeletons. Last match I played was about seven hours ago against a Druid which was the hardest fight so far. I've currently played a Force Master, two Warlords, Air Wizard, Druid, Priestess, and a Beast Master with it. I've learned I have to be VERY flexible with my strategy with this book and it's surprising how well it does so.
Yes I put attack spells in a Necromancer book. Burn me as a blasphemer if you will!!! Other than that comments and suggestions are welcome.
