Slasher

The great great great grandchild of an 8-ball, Slasher is a dangerous intravenous mix of pcp, meth, ecstasy, and cocaine. It got its street name from its creator, an infamous wasteland drug dealer known only as Jason. As a self proclaimed pre-war horror movie lover, Jason set out to make a cocktail of drugs that turned its user into a killing machine straight out of the slasher flicks of yore.

Effects

You feel elated. Your adrenaline pumps at maximum volume. Your aggression winds to a fever pitch and you become unable to focus on anything besides the thrill of the kill.

Starting on your next turn, you make an additional attack whenever you take the Attack Action. This lasts a number of rounds equal to your Constitution Modifier, minimum of 1.

If you are able to cast spells, you can’t cast them or concentrate on them while on Slasher.

Addiction

Whenever you use any amount of this drug, roll a Constitution Saving Throw. The DC for this is 10 + the number of times you have taken an addictive substance since your last Long Rest. If a character fails this save, they become addicted to Slasher until cured.

While your character is addicted, they take a point of Exhaustion for each substance they are addicted to after they complete a Long Rest.

Creatures addicted to Slasher are needlessly violent, quick to anger, and easily annoyed. Cranky and often irrational from lack of rest, those suffering from Slasher withdrawals don't usually leave the best impression on others.
