Ok so in our adventures, I found a Flask of unknown contents. Long story short: wanted to know what was in it, so I put a bit in the Dark Eldar's food, next thing we know, he's passed out cold from intoxication (so says the GM).
Going off the fact that basic stim and detox don't work on Dark Eldar, is it possible that Dark Eldar may get incredibly drunk from something standard to humans? (When they consume potatoes and it turns into vodka perhaps?)
