This is a very straightforward, yet somewhat troublesome Celestial Marshal. It's simple because it doesn't have any particularly complex mechanisms, generally just "dodge what comes out, and attack what comes out".
The trouble lies in its immunity to the vast majority of damage.
Every four attacks, the Geometric Celestial Marshal randomly changes color, only taking 44% of physical damage and damage of light and dark attributes, and it can only take double damage from elements it is weak to following the wind → earth → water → fire → wind weakness cycle. Except for the spells it is weak to, all other types of elemental damage are immune to the Geometric Celestial Marshal, and attacks of the same color and type are instead absorbed fourfold to heal it.
