I hope I am posting in the right place, and I apologize profusely if I am not, but I need some potions help.
I have a story where a potion has been prepared while people watch. It has been given to them, and they have been told who it is for. However, they do not know what it does, and wisely decide to find out before they use it.
This potion, however, can be more than one thing. The person who gets it gets to decide what it is for. I am thinking that:
This would require adding a specific new ingredient for purpose A/a different specific new ingredient for purpose B and that once the potion has been thus used, you coudln't go back and change your mind.
Does this seem to make sense? Would a potion work this way? What could I call it? A protean potion does not seem quite right, (although it sounds really cool) and it seems like something in the name ought to indicate that it can change... and being once changed is changed everywhere it is used, forever...
It also seems to me that lily of the valley is a possible ingredient in a memory potion.
I am wondering what other people think.
And if I am in the wrong spot, I do apologize... and beg to be relocated to wherever my weak mind should have put this to begin with...
