Remnant: From The Ashes [ Shade & Shatter boss fight, Max Difficulty no damage taken, solo kill ]

This is my 2nd playthrough of this game (1st playthrough was on hard mode, currently on apocalypse).
The 19th boss I encountered in my apocalypse difficulty playthrough. Nothing too hard about this fight apart from when the bosses enter protective bubble and start shooting vomit balls at me. This was hard to deal with as they get flung out unpredictably but to resolve this issue, I just ran from them and stood behind a large pillar. The slasher mobs that spawn during that whole ordeal are a bit of a nuisance but spitfire is good at clearing them quickly.
