im thinking the stats could be that it gives them maxed health with a constant draining that unless they kill more they will die by it and instead of cloaking with it cloak is turned into increased speed (so in case of dead reinger you get hit with it out and then untill it runs out you run like a scout then it recharges at a slower speed) this could be benefisal in certain sinereos but with every second they arnt attacking they are dieing which i think every ones with me on this ( its bad) but because it could be a cursed weapon like the eyelander they are forced to only use it plus the watch so they cant disquise but with the amout of health he has wont be such a big deal, it also has a starting buff of plus 25% damage and with every kill it increases by 2%, also the sword has a starting -55% clock amount with a + 45% clock regn, that way they cant abuse the watches power of speed, and with every kill it gives them back 50 health because the sword lust for blood

please leave a comment if you think of something better

plus i think a cool name for it could be (the acursed blade )
