So the past few times while doing the nightfall and encountering enemies with shields, I would sometimes bring along my Ice Breaker as I didn't have a better weapon from the situations. Several times I would break an enemies shield and kill them at the same times and would see a damage pop-up, but didn't think too much of it and thought it stated "111". I knew that couldn't be right, but figured it was just glitch. Just last week though I got a closer look and it was actually showing "!!!". This has only happened when using a weapon that could cause enough damage to break the shield (without the correct elemental type) and kill the enemy at the same time. I have no idea what this could mean. Maybe the game can't register both the ammounts of damage at the same time and just kills the enemy? If no one believes me they are more than welcome to try themselves.
