Okay starting up a new campaign and I have a player who wants his toon to be a chemist. One of his powers is a super pill that gives increases to stats. Easy, but he also wants to build into it a chance to become addicted as well if the drug is overused. How would you go about building this and what sort of limitation would that be.
Info use drug once per day minimal addiction rate, each additional dose in a day severely increases your chance to be addicted.
ps didn't there used to be a limitation for this in 4E?
Thanks for the help in advance
