Fortune has the ability to leech powers when she has physical contact with someone. A touch of skin and the powers last about 10 minutes. Although, if she ingests body fluids or blood the powers will last for however long those molecules are being digested...plus the 10 minutes when they finally pass through.
If she takes a memento from you...a tooth, hair, finger nails...she can perpetuate these powers as long at this trophy is in direct physical contact of her skin. She can only have one power at a time though, plus the abilty to drain you of yours and turn your powers on their heels* (more about this).
If she touched someone and then touches another then the power will switch over to the last power she touched. If she is digesting blood or fluids , or holding a trophy then that power trumps physical contact. However, if she touches you...in any capacity then your powers will turn.*
She is a master of your powers. There is no learning curve for her. She will know how to use them and will be able to use them at full capacity. (you have to give me a little bit of an edge here in that respect)
*When she touches you directly (complete flesh to flesh contact) your powers will reverse their effects IE: If you are fast, you are slow. If you grow big, you grow small. More subjective powers will be left to the discretion of the player...If she takes a trophy from you and uses it, you won't feel the effects of this. Reversal only happens with direct physical contact due to a chemical reaction...
If you have any questions, ideas...or protests, please let me know. Suggestions are always welcome!
