Miracle of the black-haired witch Velka. Temporary autocounter vs. heavy damage. For each sin there is a punishment, and it is the task of Goddess Velka to define the sin, and mete out the punishment.
Finishing up the year with one of the other most mechanically complicated spells of Dark Souls, Karmic Justice. This spell builds up a powerful explosion passively as one accrues damage, and releases suddenly and violently, doing major damage to one's aggressors. Let's put it together below.
Figuring Out The Pieces
|This power works well with this system...|
Karmic Justice: Divine Retribution (-5%): Crushing Innate Attack 3 (Mana Sensitive -10%; Area Effect, 2 Yards +50%; Emanation -20%; Reduced Time, Instantaneous, +20%; Trigger, 3 Injuries all within 2 seconds of one or another, Occasional, Dangerous -45%) 
The attack is 14.25 points, or rounded up, it's 15 points.
The Affliction to cast it then is
Karmic Justice: Endow (+118%): Affliction 1 (Sorcery, -15%; Based on different Attribute, Will, +20%; Advantage, Karmic Justice: Divine Retribution, +143%; Melee, C Range, -30%; Fixed Duration, 1 Minute, +0%) 
This allows one to turn on the Karmic Justice buff for 1 minute with a touch. If the person buffed is attacked 3 times in short order, they will unleash a 2 yard radius 3d crushing explosion on everyone, friend or foe alike.
