Gravitar wipes have been rare lately, but here’s a video of Aeria soloing a Gravitar run that almost wiped because two members got kicked out due to the party queue bug.
Note that her energy builder, Lightning Arc and Ball Lightning are greyed out despite the short range. That means there’s no line of sight between the two characters, so Gravitar can’t attack her. Aeria’s point blank AoE is wide enough to hit her though!
The rest of the video is pretty straightforward – enjoy 1 minute of Gravitar eating Hurricanes :p
