This could just be my view, but I feel that the number of purple crystals, especially in the ettercap quest should be cut down. It seems that the quest went from a survival test to surviving the occasional spiders from the ceiling and then running to the nearest crystal. If that seems to be unwanted, at least limit # of times they can be used. Maybe 2 or 3 healing and the same for lesser restoration. Anything that makes this quest not a "walk in the park."
Purple Crystals
People routinely die on this quest. Park walk it is not.
