Aurum Vale - morbol bosses as SCH

[Lilysparkle]

I've been having trouble with this dungeon on SCH sometimes. The morbols have their poison wave which you get rid of after a few stacks with the fruit. However, I cannot do this for my faerie. I can spam Sustain which does help, but sometimes it's not enough and I'm so busy that if I miss doing it even once, my faerie can end up dying as she has 5 stacks or so of the poison. On top of that, I know she will heal herself but it also means she isn't healing the others - and I don't know how she prioritises her heals. Essentially, the two morbol bosses in AV mean that SCH have a natural disadvantage here. Usually if she dies, it feels like the odds of winning drop dramatically. I can resummon of course, but it's precious seconds during a fight where you're not looking after the tank (I am working on Swiftcast ;x) Any suggestions?
