The way Travesty spawns her helpers near death is inaccurate. ServUo has them spawn out from under her when they actually all have tiles the spawn on, making them more spread out through out the dungeon area. Here is a video of a player on Izumo Shard. This shows perfectly how they should spawn. Also you will notice Travesty does teleport away trying to hide at this moment. The spawn occurs at 13:40 in the video. You can also see these guys are good at revealing hidden players.
