Pip can deal a lot of damage, he can slow Makoa as well. Just jump around and dont let him hook you!

After slowing skye, you can kill her easily, make sure, when she tries to turn invisible shoot a projectile to the ground, the blast will kill her. I recomend Catalyst legandary!

Try to go behind lian, then bait her away to small corners to finish it off. Be careful when you use weightless, she can easily autoim you!
