About a week or two ago I showed Ariana coming to Brave Exvius. Little did I know you be forced to use her in the event to get the full amount of prizes. That was a low blow Square Enix. That aside she isn't a bad character to have. You will need a decently leveled team to complete the whole event. Once complete you will have Dangerous Ariana fully upgraded. I know people would say why and why is she even here. I think the slicksters are Square knew people would rebel. So in the end of the event you will have a powerful character. That progresses faster than other known characters. This pretty much bribes you into using her as a free player. Pay players will bench her forever and act like the event never happen.
