Perhaps the wording of the description of rings needs to be changed.
Right now they say: 'cured rings can <do bad things for you>'.
But it really is 'rings that are -1 or worse can <do bad things for you>'.
A corpse of a previous me left a cursed ring of +3 accuracy around; I am wearing it now; and it is <doing great things for me>
Happy Holidays, everybody.
And thank you, watabou, for so much fun this year.
