Potion of Revra

Reagents:
Finely ground stone, Sand Tiger tail hair, Banta dung, Cactus thorn extract, liquified silver, Moonflower cuttings, ground Calex leg bones

Frequency:
Rare

Cost:
Expensive

Effects:
The personality of the imbiber will completely flip for twenty-four hours after the potion is taken. If they are generally docile, they will become fierce; if they are shy they will become outgoing; if they are hyper they could become calm and focused - you get the idea.

Defenses:
If you don't know the person, it's like meeting a stranger. You didn't know them before, so you won't know that they're on the potion. If you know them, they would seem different, but it would not be a problem. They still remember you and generally feel the same way about you.

Flaws:
If the potion is made incorrectly by using too much or too little Banta dung, the effects can be permenant. This is gernerally, however, a fairly safe potion.

Note: If a PC takes this, it may change his/her weaknesses for the time being. If your weakness is being rash (taking the potion makes you a clear thinker) then that is no longer a weakness. On the flip side, if you are a clear thinker (taking the potion makes you rash) then you gain a weakness.
