Need to Change Randomizer for Cursed Blade

I feel like whenever I do see this item on hit go off, it goes off consecutively with other autos. In other words, it either de-levels me by 2 or 3 levels with 3 or 4 consecutive autos, or it doesn't de-level at all.

I don't know if anyone else gets this, but this just seems really dumb. Should probably change the coding for how the on hit chance works. Because in theory, this should not be a common occurrence. This should be a very rare occurrence that you get to de-level someone two or three times in a row. But a majority of the time I see cursed blade works, it works on immediate consecutive auto attacks.
