Wand of poison is a type of wand that produces a bouncing venomous ray when zapped. If the ray hits monsters, they will become poisoned and suffer damage at regular intervals; such damage seems to be in range of 15-30 (whether it depends on character level/attributes and status of wand needs further testing). Hitting the same monster repeatedly with a venomous ray is believed to increase the frequency at which the poison effect is applied. This wand has a range of 10/6/3 for B/U/C respectively. Additional 1 range is added for each 5 character levels.
