My mech build is approximately vanilla endgame, which is when the Dantalion is supposed to be beaten. However, the boss's stats are just too huge. It and it's orb things take very little damage (a full hit from both of my arms can geal almost a 1000), as a result i can't destroy the orbs quickly enough (even if i stop aiming at the boss at all), run out of space to dodge and get melted.
