SFS Standard All In Feat 17

Prerequisites Double or Nothing
Requirements You haven’t used your lucky number yet today.

You can go all in on your luck in the present moment at the expense of your luck in the future. Before you roll a check, you can choose to expend both uses of your lucky number to count the roll as a 20. The effort strains your relationship with the primal forces of luck, so you don't get a lucky number tomorrow.
