Fabulous Fatburners: Since herbalism isn't an exact science, it's a bit difficult to equally dose the small tablets. As such, 1 in 20 tablets will have one of the following effects: diarrhoea / tiredness / general illness caused by stomach problems. These discomforts will generally last one full day. The effect can be halved by a successful Constitution check against a DC of 15. The tablets will give the user a +2 bonus to all Constitution checks involving physical exercises (and make you look really fit and skinny while running from the town guards). Rippen charges 4 Crowns per phial. As he figures the good-looking and charming don't really need these tablets, he'll charge a 10% extra for every +1 Charisma bonus the buyer has (up to a maximum of 40%) and blame it on shortages, the new taxes on herbs or the downpours ruining the yield.

Joyful Tears Potion: There's an 80% chance the Tears potion will be available at Rippen's. When it's not, and Titus is asked about it, he'll act as if conspiring against the crown and informs the potential customers that for a small extra price (the adventurers are very well dressed and obviously connoisseurs, by the way), he might be able to get his hands on a vial. Such a container typically holds 3 uses and can be purchased for 25 shiny Crowns. (Except for Lovely Lucy, the Madam of the Velvet Gloves Club, who will get the Tears potion at a sharp discount, equalling Rippen's discount at her establishment).
When purchased (or otherwise obtained) there is an 85 % chance the Tears potion will actually work. (This is probably the reason why Rippen insists that one uses it with alcohol and body oil; both of which he sells incidentally...). When someone under the effect of the potion gets the feeling of being turned down for whatever reason - a refusal of access to some place, a turned down job offer, or even a simple 'No thank you' when offering someone a drink - strong emotions tend to surface, resulting in quiet sobbing in a corner to outright anger. A successful Will check (DC 15) is needed to negate this effect.

Mental Mirroring Mix: As Ayasca is a mixture of herbs, it can be ingested or simply mixed with tobacco and smoked. A typical batch of 20 grams will have 5 uses and will cost you 40 Crowns. Ayasca will grant the user a +1 bonus to all sense-related checks (smelling, tasting, listening, seeing, touching), but will induce a certain craving for food and snacks throughout the entire time the user is under the influence (1D4+1 hours). This bonus is cumulative with the number of uses, up to a maximum of 5, but taking more than three doses or taking one dose in combination with the Joyful Tears potion will put the character under the effect of a Major Image spell (PHB 252). The exact nature of the illusion is left to the DM.

Moon Dust: The exact effects of Moonwing Dust can be found in the Monsternomicon on page 128 under the header Combat.

Sowles Brew: After the second pint of Sowles Brew, characters are required to make Constitution checks vs a DC of 10. Each consecutive pint will increase the DC by 5. Failing a Constition check results in passing out; or in case of missing the target number by more than 10, throwing up and then passing out. Cask Imps inevitably go berserk when removed from a barrel of Sowles Brew. They attack whoever disturbed them and fight to the death. When drinking Sowles Brew, one is much more vulnerable to the Drunken Domination quality of the Cask Imp. Only 1 pint within the last hour is enough for the imp to try and take control and the Will save DC is increased to 18.
