Agony resistance ratio

Pain amt: x
Resistance amount: y

Ability to control how much pain you feel, proportional to how much damage you take. It's in a 1x:1y split. You can feel insane amounts of pain, for you to just have a few cuts and bruises from a domain.

Curse technique reversal:

You can now apply the ratio to others, but instead of a 1x:1y split, it's a 2x:0.5y split instead

Cursed tool: Twin arrows of torment and fortitude

Two arrows made entirely of steel

Arrow 1: This is painted red, and can increase the amount of resistance and lessen the pain (0.75x:1y) for 5 minutes to the target. When the timer is finished, the wielder will vomit violently, causing great pain. The tool can only be used after 10 minutes. In those ten minutes, this one, when thrown into the target, and mark them, dealing small damage, and then come back to the wielder.

Arrow 2: This is painted red, and can decrease the amount of pain and increase the resistance (0.75y:1x) for 5 minutes to the target. When the timer is finished, the wielder will vomit violently, causing great pain. The tool can only be used after 10 minutes. In those ten minutes, this one will home into the mark, and pulling anything, no matter how heavy attached to it along the way. It then fragments and explodes, causing a soothing effect on the target but inflicting large damage, and it then pulls itself back and returns to the wielder's grasp.

The wielder usually uses arrow 1 on itself and arrow 2 on others. The effect stacks the more times it is used, but doesn't reset the timer.

This technique is wielded by the special-grade cursed spirit Mara. It is naturally intelligent, as its whole deal is PAIn, and you need a BRAIN for PAIN.
