Blue rings are really useful for escaping trouble, although it can be a case of jumping out of the frying pan into the fire! To use a blue ring you need to have at least a bonus of 140 in magic worn ring. To use the blue ring you use the syntax 'twist blue ring' and you will be magically transported through space to another random location. So, if you find yourself being chased by Sgt Angua and a few cheetahs you might want to use it.
