I am in the process of picking up a second hand copy of Arkham Horror the LCG. I will be getting the core set, and the complete Dunwich cycle all in one go.My understanding is that I can use the Dunwich characters in the core set. My lovely bride and I tend to get attached to the characters.My question is: With the content listed above, is there any possibility of making a vaild "Spellcaster" kind of like the old professor Harvey Walters in the Arkham Horror Boardgame. Someone who uses spells as their primary form of attack, defense, search, etc.
