Cigs: -1 cha
And if drug builds don't really care about the debuff why do you want to keep it?
Characters who rely heavily on drugs don't do anything unless they are drugged
Ok so with chem reliant everything can be permanent addiction, which means you can have what -6 maximum ap? what happens when you have less than enough ap to take the drugs in the first place?
Dunno I had quite a nice fun with my 5 AP jet addict big gunner last season. It was funny. Personally I like the idea for different withdrawal effects but I think that making them give - to stats that already at 1 wouldn't work. Maybe it would be better to make them give randomly -1 AP or -2 to one of the player stat or -60% to all skills and these withdrawals would go around randomly after 1-2 hours. But it would be hard to implement and most players hate randomness still I think it would be an interesting thing.
