So I have been seeing a lot of people hating the final boss for tempest island on vet. Complaining about that lunge of hers or her aoe she does and I figured I would give everyone that is having issues with that boss some pointers. Simplest thing that helps you a lot is knowing what distances to keep from her and close to her. Now her aoe and lunges are based on certain distance quotas. You are either too far or too near and either one of those two will proc said associated skill of hers. The easiest way I have found to dealing with her is having the tank try to lure her to the cliff part when you go up the stairs to boss fight look right and you will see that ledge. Now have one person equipped with the grothdarr head and shoulder piece and when their grothdarr procs you can see the safe distance from her, keep like 3 or so feet from the ring tip of grothdarr for person wearing it and then everyone knows the safe distance from her. That spot I said about not too much of her windstorms go over there and a lot of her attacks fail there. The battle becomes cake work. If you do this trick she will never use her aoe or lunge attack save for the one where you have the tank pull her there. But note this that she may sometimes move in battle but it is not too terribly hard when dealing with that because she does not often move too far from original placement though. If this video helps https://www.youtube.com/watch?v=n6MMNhOwwkU but you don't want to go to the left of the staircase really or be in the center of the fight area because of the wind storms. Keep around the edge of the fight areas is crucial. Also where I was looking at in the video behind my character is where you don't want to go either. I was doing it on normal just to showcase but I have done this dungeon on vet solo only once and it is still the same practice.
