Seems somewhat unfair to the person who first accidentally discovered the fact that 20.6 monsters drop 18.x rings. (I'm banking on the fact that the discovery was accidental because most players don't think "Oh hey this monster's 20.6, which means I can get an 18.x ring from it.... let's go kill it!" )
Anyway, I'm amused too. But I do wonder whether people who got and salvaged all of their 18.x rings *cough*myself*cough* will get an abuse ring or an integrity ring.
