So I started a new game to try out the turn based mode (I like it so far, even if it's kind of slow), but it's really made me notice how often grazes occur. It seems like a ludicrous number of my attacks result in grazes, even when my to-hit chance on each character is 85% or higher on most enemies. I noticed it first during the first little dungeon when you just have Eder with you, and it has been keeping up, so I decided to actually track how many attacks I made during the Engwithan Dig Site and how many resulted in grazes. It's almost 80%. What gives?
