As a Summoner damage dealer in the exact fight shown in the video, I was given the opportunity as delegated to me by the other 7 players, that I was allowed to use our level 3 Limit Break to take out the Infernal Nails shown above. This wasn't me in the video, but it's a very similar situation that I found funnily enough. Even better, your character throws his arms open and probably laughs and yells into the air as it comes down as well just like I had to do when I casted Meteor for the first time. That's my blog for the day.
