Ars Magica BackerKit is running until Nov 14th. This is for a deluxe version of Ars Magica 5th edition (i.e. the current edition) in a slipcase. Not a new edition and all current 5th edition supplements should work fine (which is good since I bought them all in five Bundle of Holdings at about $40 each).

• The massive Ars Magica Definitive Edition core rulebook
• The essential Reference Guide booklet
• 3-panel Storyguide Screen
• Poster map of Mythic Europe featuring new art
• Premium slipcover to hold them all
• Set of six 10-sided "Transmutation Dice" made of 100% recycled plastic
• Stretch Goals that release Ars Magica as Open License
