The rules are not clear. Do all spells have an Energy of 1 unless showing a higher value? I cant believe the rules dont state this in an obvious fashion somwhere.
Can Waterbolt go around corners like Featherweight? If you 'Knockback' yourself for 3 movement but there is only 2 squares of straight line to use do you take 1 damage for the remaining movement that bumps into a wall?
