Topic: Surprise Attack vs. Attack from Behind
Are they the same thing? Are they different? Do they stack?
Surprise (pg. 56): No mention of modifiers to attacks, just says "The foes of surprised characters can take a free action before Initiative is rolled".
Attacking from Behind (pg.58): "If a character is attacked from behind by an enemy he is not aware of, he loses all Dexterity and shield modifiers to AC and the enemy receives a further +2 bonus to hit."
The Character Sheet U. (pg.167): "Surprised AC is Melee without shield of Dexterity modifiers, with a further 2-point penalty".
Does these mean that a Surprise Attack from Behind is effectively a +4 attack (-2 to AC, +2 to attack), with loss of shield and Dex mods (+6 if you're a Specialist Sneak Attacking)?
For that matter, does Surprise/Attacking from Behind also remove negative Dex modifiers to AC?
