RETURNAL | R_A.0762 Echoing Ruins Containment Room [Melee + Thermogenic Launcher] (HDR) NO DAMAGE

This clip has me clearing the Echoing Ruins Containment Room with the seldom-used Thermogenic Launcher and the never-before-featured Mega Rocket trait.
A few items of note:
First, as briefly seen at 0:17, the statuary scattered across Atropos occasionally contains a Lamiadon. The sudden appearance of a new hostile can prove quite vexing for many players! Insofar as I can tell, there is no outward sign when a statue hides an unexpected hostile-but if you know something I don't, please leave a comment below.
Second, I am irritated by the missed melee attack at 0:28. Am I alone in finding that RETURNAL's melee attacks sometimes miss when all evidence suggests they shouldn't?
Furthermore, the Atropian Blade synergizes brilliantly with the Dash Blast artifact. In the initial few seconds of Round III, beginning at 0:51, I clear the tile of the Gyropods that spawn by slaying one with a melee attack, Dashing to interrupt the animation after the kill is registered, and letting the triggered Dash Blast incapacitate yet another hostile.
