Message: <blockquote data-quote="Hypersmurf" data-source="post: 2666774" data-attributes="member: 1656">There's only one straight line from centre-of-square to centre-of-square.But the rules for charging state that if any line from square to square is blocked, you can't charge.  Since we know that centre to centre only provides one line, and the charge rules refer to the possibility of multiple lines ('any line' rather than 'the line'), the determination of charge-path-validity cannot be referring to a simple centre-to-centre check.Take this situation:[code]-----|...|   #[color=SlateGray]o[/color]##|...|   [color=white]@[/color]|...[color=brown]+[/color]####-----[/code]I want to shoot the goblin.To determine whether your target has cover from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target’s square passes through a square or border that blocks line of effect or provides cover, or through a square occupied by a creature, the target has cover (+4 to AC).If I pick the southwest or southeast corner of my square, some of my lines pass through the wall, and the goblin has cover.  But if I pick the northwest or northeast corner, none of the lines pass through squares or borders that provide cover, or through a square occupied by a creature (that isn't the goblin, anyway), and so the goblin does not have cover.  I can shoot him at no penalty.The goblin has a mace, and wants to hit me.When making a melee attack against an adjacent target, your target has cover if any line from your square to the target’s square goes through a wall (including a low wall).Well, if I draw a line from somewhere in the southeast of the goblin's square to somewhere in the southeast of my square, it passes through a wall, so I have cover against the goblin.  If I draw a line from northwest to northwest, there's no intervening wall, but that doesn't matter... I have cover if any line passes through a wall.Since I have cover, the goblin doesn't get an AoO when I shoot.Notice how the rule that prohibits charging uses the same wording - if any line between the squares is blocked, you can't charge.-Hyp.</blockquote>
