Bound Until Death: The Wraith Blade takes the form of a beam of energy in the vague shape of a waving longsword, extending from your palm. You are proficient with this weapon, and is considered a one-handed finesse weapon that deals 1d8 force damage to begin with.  The Wraith Blade can be summoned/dismissed at will.

Turning Against You: For every killing blow done with the wraith blade, its damage die increases as it consumes the soul of its victim.When the blade is fully charged (3d6) and you kill another creature, the blade will turn against you. It will require a Constitution save, DC: 20. It will return to a lower damage die for each 2 rounds you refrain from using the blade. On a short or long rest it returns to it's normal state.

-If you fail the Con Save, you take the max damage of the current damage dice, and are dropped down to the previous damage dice. On your next turn, it will require another save and repeat the process.

-If you succeed the con save you roll out the damage, and you may continue using the blade in that damage state, although you will have disadvantage on subsequent rolls.

Damage Dice: 1d8, 1d10, 1d12, 2d6, 3d6 (max)

Proficiency with a Longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Damage: Force, Touching this sword drains all of your health, and upon succesfully rolling your death saves, you are bonded together. Healing will not help during attunement., Versatile, Sap
