Nothing is story mode is hard after they nerfed Steps of Faith - that was the only one with some difficulty but not anymore.
Each boss now can be explained in a few lines of instructions.
The Chrysalis:
Boss go in middle - run into balls around room - alternate if possible
Meteor phase - tanks catch meteors - dps kill vortex

You can choose to explain more if you want but it is not really necessary and lol@healing chrysalis is hard. The boss gives you huge ass cast time warning that double/triple is coming and THEN casts sparks, we don't get that luxury in coil much.
