Inflict Wounds Specialist

You always have the Inflict Wounds spell prepared.
Your unarmed melee attacks can be used as the Somatic/Touch means for the spell Inflict Wounds.
Your martial arts proficiency allows you to convey the spell of Inflict Wounds as a reaction by your gesture of fists that can be used as unarmed strikes.
This elaborate technique allows you to transcend your hero's unarmed strikes to a necrotic combo flurry.

You may use your Reaction and spend a spell slot to cast  Inflict Wounds that will be casted as a buff for only this turn for your unarmed Strikes with a diminishing effect*.

*Diminishing effect
For every extra attack you do on your turn when you use Ki Wounds Specialist, divide the damage by the total attacks (rounded up).
Example:  1st attack = Unarmed Damage + Inflict Wounds Roll
                  2nd attack = Unarmed Damage + (Inflict Wounds Rolled / 2)(rounded up minimum of 1)
                  3rd attack  = Unarmed Damage + (Inflict Wounds Rolled /3)(rounded up minimum of 1)

You only roll once for your Inflict Wounds damage and use that as a buff to your consequent attacks.
On a Natural 20 you have the option to reroll the Inflict Wounds Damage buff or double the existing buff.
