Dumb manoeuvre

As a reaction, you can turn one of your natural twenty rolls into a 1

victorious loser

if you drop to one hit point or less, target two creatures, the targeted creatures must make a constitution saving throw (DC = 8 + your proficiency bonus + your Constitution modifier), on a failure or a natural twenty roll, they are reduced to the same amount of hit points as you.

if another creature you see rolls a one, you can choose to deal a number of d12 equal to your proficiency bonus to them as bludgeoning, piercing, or slashing damage (your choice)
