Longsword of Ilneval

This longsword is blessed by the orc god Ilneval
and gives a +2 bonus to attack and damage rolls
made with it. Its wicked edge cuts jagged wounds
that are harder to heal. When you hit with this
weapon, you deal an extra die of damage.
In addition, when you hit a target, the target must succeed a Constitution saving throw equal to half
the damage you dealt rounded down or 10,
whichever is higher. On a failed save, the target
cannot heal the damage you dealt until they take
a long or short
