Character: Ikai Authosk
Gamespy ID: blackwyrmdude
Nothing like described in the description of this drug happened. Actually, it had no effect at all. The character is not immune to drugs, to my knowledge, I don't think the dealer ripped me off, so, it's likely a bug. I tried it twice, and no effect.

Where did you get it? That's a legacy item that shouldn't really be in the module at all.
