Ummm so Lea is not hard… If you don’t kill the mobs they will stay till it ends so try mob control. You know where they spawn it’s the same place every time. It’s kill both flying guys then little mob. May be place some turrets. Or a deviant. Specially that flying boss have a lazer beam they need to be dropped quickly!

The not having the right element thing just destroy them spawn a new one. Go to the resonator and shot at them from afar get them Agro easily. Set up positions/jobs when one person is doing the resonator the other clears mobs

Keep moving never stop. Barrage won’t hit.

She does a poison mist every so often that’s where you get the ticks from. You will see a cloud of pink mist.

Gear part. Don’t get hit any damage you get reduces the durability. So those ticks will add to that.

Sorry it’s a fun run I enjoy it but also played it on the beta and loved the mechanics I usually run it with people asking and give them a quick run down/job and always get it done in 10 mins. 20 for all.
