Tempest: The Final Chapter - ROOT ABYSS!

I haven't gotten a chance to try out Chaos versions of the bosses, but just from watching Normal mode, they're all laughable joke bosses (no offense). I don't find it challenging at all, its like standard routine. I only died once out of the 4 bosses (on the 1st boss on the left the clock bird boss), probably because I watched video of each boss once, but thats enough to get their attack pattern down easily.
