Backstab
Playtest 3.2 / 4th EdSkill Rules & Full Description
When this skill is purchased the character gains a +1.5 Damage Bonus to all their attacks from behind with any weapon. This skill is not hand specific and applies to both their right and left hand weapons. The character must be approximately 90 degrees behind their target to be considered behind them. The character cannot reach their arms around the target to gain their Damage Bonus.
Additionally, if the target character is Disadvantaged, the character gets their Backstab Bonus. A character is considered to be Disadvantaged if they are under the following effects: Stunned, Paralyzed, Enfeebled, Pain, Confusion, Sleep, Unconscious, Unarmed or if both arms are: Bound, Disabled, Broken, Withered, or Severed. A character is not Disadvantaged if they are: surprised, blind, weakened, etc.
This skill is stackable with itself and all Backstabs learned are cumulative. So a Backstab +4 would allow the character to cause 7 points of damage with their Small Weapon.
