Yeah, I was faster than her, and I had an inventory slot empty (even two, I traded an item out when I realize it didn't work, just to be shure 😄 ). I used rally speed to outspeed both of the lord that's how I was able to steal Dimitri's ring. I wanted to share my discovery, because the lord that has the precision ring (who ever it is, he's always located on the left ) might join the battle if you're too slow, but as it seems impossible to steal the ring, there is no need to rush like I did.
