Agony and Irony

Ancient Elven daggers, these elegant blades are shaped unlike any weapon in the Modern Kingdom.  Called in the ancient Elven tongue "Ul'aks" They swing around the fist and down the arm, these "swingblades" are capable of slicing and stabbing positions, and are designed to compliment the natural motions of a person's arms and hands in close combat. The serrated edge is used for blocking other bladed weapons. Irony and Agony are two particularly enchanted versions of the already deadly elven weapons; glowing with a tinge of green along the blade of Irony and a deep crackling purple energy that seems to leak from Agony

Agony and Irony are bound together by their enchantment; they must be attuned to and used in tandem. If you attack a target with either Agony or Irony, you must make your next attack action or action to attack with the other blade, if the first blade's target is killed, this effect is negated. Failure for any reason to meet the requirement results in the wielder taking 4d10 Necrotic damage. Additionally,  should agony and Irony be separated by more than 5ft for any reason at any time, the attuned wielder will immediately feel an overwhelming desire to return them to each other; failure to do so will result in the wielder taking 4d10 psychic damage per round that the blades remain apart.
