Lol when I heard that items can be ruined with runes of corruption I thought like bricked or something in a way that your affixes get messed up and such but you can literally get an item to be ruined and you cannot equip it anymore. Not complainin just did not read too much into patch notes to know this can happen. I love the corruption so far though and the crazy items that can drop from…breaches. Imma call em that
The probability of ruining your item is also nicely low. In your case with the ring: 5%
(25% negative outcome and then 20% of getting ruined)
