Meh, i wouldnt wanna enhance luck anyway as it is on 10 always, because luck makes me the wizard of california!
Jokes aside, i don't care much about luck anyway, its either on 1 or 6 in my characters (yes i like a good exploding gun in my face). But +LK is a thing that doesnt make much sense to me from the realistic game view i share with some other hippsters players.
Drugs should always be thought out well and balanced with already existing drugs.
As this drug doesnt change much I rather go the lexx-way and say it's nonsense to get something trivial like +1 LK as it is only 1% crit and some stuff on roll-tables we mostly don't know anything about.
oh and I also thought this suggestion is about voodoo dolls and stuff.
