I don't know if it's the case for the moment (I have tried but with no results )but may I suggest this
After [A] weeks AND B doses a girl is given a trait
- Fairy Dust: gives Strong
- MagicViras: gives Nymphomaniac
- Shroud Mushroom: gives Broken Will
After [C] weeks (C<=A) OR (AND?) [D] (D<=B) doses of a drug girl is given Mind Fucked And a chance of death by overdose if more than 1 dose is taken each week
PS: I have a problem with a bold tag (my B var) that I can't remove or edit
