The unique effect reads “Your minion’s attacks have a chance to randomly inflict Decrepify or Iron Maiden”, and I noticed the 2 effects (a damage over time and slow down) keeps getting applied to my own character
I have the same issue, makes Blood moon breaches quite difficult to use effectively, when you’re slowed. The Iron Maiden doesn’t do much damage, but the slowing is terrible… This has to be a bug right?
