First impressions was wow, spot on and finally! Unfortinatly the endfight is bugged. All the friendly characters and myself are hitting the boss but he just stands there in a battle pose doing nothing and taking no damage at all. Also minor bug getting a empty achievement stepping into the machine.
Bugs with crystals: Simple synergy crystal of defense, physical offense and magical offense have no stats on them and are stated with "cleric" tag. (I R warrior)
