Ruby Nightmare Blade

4th-level / Diamond Mind

Prerequisite: Two Diamond Mind maneuvers

Initiation Action: Attack

Range: Melee Attack

Target: One creature

The ruby nightmare blade is a favored finishing move of warriors who study the Diamond Mind discipline. By intently analyzing your foe’s stance and moves, you find the precise spot that you must strike to end the fight with a decisive blow. You attempt an Intelligence (Insight) or Wisdom (Insight) check as part of this maneuver, using the target creature’s AC as the DC of the check. If your check succeeds, this melee attack deals double damage. If your check fails, your attack is made with a –2 penalty to the attack roll and deals only normal melee damage.
