Flanking

Source PRPG Core Rulebook pg. 197
When making a melee attack, you get a +2 flanking bonus if your opponent is threatened by another enemy character or creature on its opposite border or opposite corner.

When in doubt about whether two characters flank an opponent in the middle, trace an imaginary line between the two attackers’ centers. If the line passes through opposite borders of the opponent’s space (including corners of those borders), then the opponent is flanked.

Exception: If a flanker takes up more than 1 square, it gets the flanking bonus if any square it occupies counts for flanking.

Only a creature or character that threatens the defender can help an attacker get a flanking bonus.

Creatures with a reach of 0 feet can’t flank an opponent.
