They included 3 diagrams for flanking in the book. The first shows standard flanking, in included the fact that someone stunned or other wise helpless cannot provide flanking bonus even if they are in position to do so. The second shows a group flanking a large creature. The last shows Tordek being surrounded by 4 monsters. Tordek is base to base with a troll and has a ogre 5 ft behind him. It notes that both the troll and the ogre get flanking because they both have reach. On the other axis a orc is base to base with Tordek with and a Hobgoblin is 5 ft back with a 10 ft reach weapon. The hobgoblin is noted to have the flank bonus and the orc does not have it. However I just noticed the text to the side saying that the ORC should get flanking bonus.Without having RC because I hate everything about the book, all I can go on is your summation. And that rule sounds hella dumb. Either each person is threatening the enemy or they're not. If they're not both threatening the enemy, they can't be flanking. If they both are threatening the enemy and in flanking position, both alies get the flanking bonus.
In the case of one w/ reach weapon and the other person not having one, the reach guy would be 10 ft away on one side and the other ally would be adjacent to the enemy on the other, and both would get flanking benefits.
Thank you for all your help, but the main question still up in the air. I plan on making a Psychic Warrior/Rogue whoes primary role is a sniper that can use his sneak attack and psionic shot feat with a bow or corss bow's maximum range between 80 to 120 feet away. Assides dipping into another class for extra range in sneak attack. Are there feats that increases the maximum distance sneak attacks can be done from equivalent to a bow or cross bow's maximum range of 80 to 120 feet away.
On the other axis a orc is base to base with Tordek with and a Hobgoblin is 5 ft back with a 10 ft reach weapon. The hobgoblin is noted to have the flank bonus and the orc does not have it. However I just noticed the text to the side saying that the ORC should get flanking bonus.
Because you are not flanking as defined by the game rules.If someone in engaged in melee and you circle around and shoot them in the back, why should not get sneak attack?
