Memnons Discordant Blade

This barbed greatsword's red blade trails a shower of sparks when swung to strike.

Bonus. +1 greatsword. Can only be wielded by a chaotic being. If you also wield Memnon's Entropic Armor and Memnon's Blazing Javelin, it becomes a +3 greatsword.

Benefit. Once per day, you can utterly annihilate one creature of level 9 or less that you damage with this blade. The creature can pass a DC 18 Constitution check to take 3d8 damage instead.

Curse. You cannot relinquish ownership of this blade unless it is taken from you by a creature that defeats you in combat. For each day you do not slay a LV 2 or greater creature with this sword, you lose 1d6 hit points. These are restored only when you kill a LV 2 or greater creature with the sword.
