Potion of hallucination

A potion of hallucination can be quaffed to cause hallucination; blessed potions cause to to hallucinate for fewer turns (300-499), uncursed for a medium number (600-799), and cursed for a long time (900-1099). Potions of hallucination have a base cost of 100 and can be turned into water by #dipping a unicorn horn in them. They have very little use (though they are excellent for causing funny messages); one potential use is to quaff them in place of magic resistance when attacked by a creature with the touch of death, as hallucination protects against that attack.
