Lethal
Causes total organ failure shortly after consumption. Lethal is a tier-4 effect that adds +0% of the product's base value to the sell price and contributes 0.000 addictiveness to the customer. Like all effects it stacks with the others already on a product, up to the 8-effect limit, and it can be mixed onto any product in the game.
Which Ingredient Adds It
No ingredient in the v0.4.7 data adds Lethal directly — the ingredient shelf reaches 16 of the game's 35 effects, and this is not one of them. It can still appear on a product through effect transformations during mixing or as part of scripted content; the transformation table is derived from the game's own mix-map data, and this page will list every confirmed chain once they are nailed down.
Best Recipe to Get Lethal
No mixing sequence in v0.4.7 ends with Lethal on any product — the solver explored every ingredient chain up to 8 ingredients and none lands on it. It is effectively unobtainable through the mixing station.
Transformations
Mixing does not only append effects — under v0.4.7 rules an ingredient first applies its transformation table (if-effect-present → replace-with) to the effects already in the bucket, and only then adds its own default effect if there is room. That is exactly how Lethal can appear on a product even when no ingredient carries it: another effect gets converted into it mid-mix. The full 114-rule table is derived from the game's own mix-map data and every recipe on this site runs it. Lethal is not the initial effect on any product.
Price Multiplier
Lethal adds +0% of the base value. Because the bonus scales with the product's base price, the same effect is worth a different dollar amount depending on what you mix it onto:
| Product | Base price | Sell price with Lethal | Value added |
|---|---|---|---|
| OG Kush | $35 | $35 | +$0 |
| Meth | $70 | $70 | +$0 |
| Cocaine | $150 | $150 | +$0 |
Note the zero: Lethal's bonus is 0%, so the sell price does not move. It is in the game data with a full effect profile, but it never contributes to price — mixing it into a profit build only spends an ingredient and one of the 8 effect slots.
Full formula: sell price = base × (1 + the sum of every effect's bonus), rounded to the whole dollar — the same math the mixing calculator runs for any ingredient chain.
Products That Want It
No best mix on this site uses Lethal: it adds nothing to the sell price, so it never beats any priced effect for a slot. Its place is in quest solutions and deliberate product design, not profit mixing. If you need it on a product anyway, the calculator will show what it costs you.
