The streamlining continues. The cover rules for spells were bulky and confusing. I tossed them out. Now, what a spell can hit is determined by its range.
A Close range spell can hit just about anything to which it has a direct, unobstructed line: from offensive posture to offensive posture. "+ 4 difficulty.
A Short range spell can hit targets further away, or those with a little bit of cover. Read: offensive or defensive enemies. 0 difficulty.
A Medium range spell can hit targets who are out of combat, or those who would otherwise be very difficult to hit. -4 difficulty.
A Long range spell can affect just about anything – see Rule Zero for clarification. -8 difficulty.
