4:29 is the part where the plot armor comes in clutch

I have a tip for the boss.

I defeated the boss when i still had the ambush set that i used to beat the crab in helix, although i used the lava plume set first to get to the boss since the dodge rate wasn't helping against the hord of enemies like the moths and robots.I had a hard time but using the stalling tactic and also knowing every move of the enemy helped.I was level 85 and still am because i dont really grind much yet .
