Prepare for Supreme Chaos (Rumiel)
Prepare for Death Ray before the first turn: the card explicitly says W then S to dodge. For Diffraction, listen to the random rhythm, wait through four preparation beats, then reproduce it with parries. Light Divide gives a facing-direction cue; a landed hit adds Bleed +5 and severs a limb.
Reality Crusher explicitly ignores Undying Heart. The September 3 official message confirms a Gamma Drill duration increase but not an exact percentage. The public card now lists 320 HP; neither that documentation edit nor a video proves when the live game changed.

Official changelog · Sep 03: The official changelog says Gamma Drill duration increased and describes the amount as around 25%+??. The increase is official; the exact percentage remains uncertain. Open the Discord source
September 6 documentation correction: the current Rumiel card no longer lists Block, Parry or Dodge chances. Earlier copied values of 0%, 0% and 20% are now shown as Unknown. Removing those fields is not proof that Rumiel lost those abilities in the game. Use the published move cues below and the combat-response guide, not an assumed reaction percentage.
