Flaw - Addiction - Smoking

You started young, most likely, maybe with your grandfather's pipe or one that you found in an old box.  At first, it was for fun, or to look more grown up, or to impress your friends, or a love interest, but it soon became a habit that you did whenever you were bored, or when you were afraid.  Now, it has developed into an addiction, one  you cannot ignore for any extended length of time.  Your pipe and tobacco pouch are among the items you think of first, and when the pouch is growing light and in danger of running out, you grow nervous about where and when you will be able to re-fill it. 

You cannot go more than a couple hours without lighting up your pipe and smoking a bowl of tobacco.  If you go more than 3 hours, you begin to grow jittery, which causes a -1 penalty to any stealth ability rolls.  Your DM may allow you some sort of advantage to any intimidation ability check due to your irritability.   The smoking habit has also affected your general health, giving you a disadvantage on any athletics ability roll where endurance is at question, as well as a disadvantage to all Constitution saving throws.

FLAW. This is a flaw feat. At your DM's discretion, you may take this feat at level 1.  If you do, you may also gain a second feat, or increase two of your ability scores by +1 (or one by +2).  If you choose to increase any scores, you cannot choose to increase any score affected by the Flaw.  Some flaws can be overcome in time, with role played work towards that end.  Others might be overcome by a high-level Cleric, but the cost might involve a side quest or a great amount of money.
