Dreamlily Effects: 

Consuming dreamlily causes disorienting euphoria and brings about remarkable resistance to pain. A creature under the effects of dreamlily is poisoned for 1 hour. While poisoned in this way, the creature is immune to fear, and the first time it drops to 0 hit points without being killed outright, it drops to 1 hit point instead. A dose of dreamlily costs around 1 gp, or up to ten times that if purchased through legal channels. 

Initial Effect: If a user fails an initial DC 12 CON save, he feels completely at peace for 8 hours. During this time, the user can operate normally while at 0 to —4 hit points. At —5 hit points the user is disabled, and at —6 or lower he becomes unconscious. Also, he is immune to fear effects.
Secondary Effect: If a user fails a secondary DC 12 CON save, he takes 1d4 points of Wisdom damage.
Side Effects: Users can take only a single action in each round while under the effects of dreamlily.
Overdose: If the user fails a DC 10 CON save (which includes the penalty mentioned below), he imbibes too much and takes 2d4 points of damage.
Special: A dreamlily addict takes a —2 penalty on CON saving throws. This effect lasts until he manages to break the addiction.

If a user becomes addicted, he must either satisfy his desire for the drug or attempt the same saving throw each day. (The save DC rises to 25 for someone who remains addicted for two months.) A user can satisfy his desire for the drug for two days by taking one dose. If he does not continue taking the drug or if he fails an addiction saving throw, he loses 1d6 points of Dexterity, 1d6 points of Wisdom, and 1d2 points of Constitution. If a user succeeds on two consecutive addiction saving throws, he breaks the addiction. Lesser restoration and restoration heal ability damage in the short term; remove disease breaks the addiction; greater restoration or heal does both.
