You may ignore 1 figure or obstacle when tracing line of sight for a Ranged or Magic attack.
So i just want to confirm obstacles are things like water pit rock etc. I have someone in my game saying he can shoot through a wall to hit my sorcerer on the other side. the wall he is shooting through does not exist its just a perfectly spaced square in between the dungeon walls you can't put anything there..
can that be considered an obstacle he can shoot through?
