Dreamfruit is a nickname given to the fruit of various planets from a number of different worlds which have a powerful neurological effect. Consuming dreamfruit that has been prepared correctly increases the depth of an individual's mental reserves, and creates mild feelings of calm contemplation. When consumed unprepared, it is merely a mild stimulant and can cause gastrointestinal distress.
Dreamfruit is a type of Exotic Biotic - an Exotic Substance related to Life Science. A physrep of small fruits or a vial of liquid essence can be used to represent a few measures of this substance, but particularly large physreps can hold more.
When applied to a character, a measure of Dreamfruit increases their Maximum Psi Points or Will Points by one. If a character has both Psi Points and Will Points then they must choose which one the Dreamfruit increases (strike through the one not chosen with a pen). The Dreamfruit also grants a single Point of whichever type is chosen (so a character with a maximum of 2 Psi Points who has spent one that day increases their Maximum Psi Points to 3, and now has 2 Psi Points).
As with all Exotic Substances, a character with at least 1 rank in the relevant speciality (Life Science in this case) can spend 1 minute of appropriate roleplaying to apply 1 measure of Dreamfruit to a character. After this roleplaying, they should unpeel the sticker that represents this substance, stick it to the target's character sheet, and record the current date on it.
The boost provided by this substance wears off at time-in the following day.
