An additional help for Divebombs, you can focus target Twintania. When she releases the second neurolink, the focus will be gone. When she starts to use her divebombs, you'll see the focus target pop'ng again with its cast bar. You have like... 3 indicators when you're about to get nuked: The big icon on the target's head. The alarm sound of the target. If you focused Twinty, you'll see the focus target and its cast bar. There was a video that helped me a lot back then. This is the link: https://www.youtube.com/watch?v=anq6_iVjUHo It's pretty short and it explains the basics.During Twisters, it's not necesary to start moving when she starts to cast it, but you can start moving at the 50% of her cast. Again, focus targeting Twintania helps a lot in this phase, besides the DPS/healer positioning in order to avoid the Dreadknight to reach them and kill them.

When you go past that phase (Dreadknights/Twisters), the battle becomes really easy. At that point, you pretty much have the victory in your hands. There're very little elements that could make you fail at that point.
