In episode 9 of That Time I Got Reincarnated as a Slime (time code 7:44 at Crunchyroll) Rimuru uses a new skill he got from Shizu, called Degenerate.
I wanted to test out Degenerate
I think this may be an awkward translation. First, its pronunciation is different between its noun and verb forms, with the verb using a long "a" sound in the final syllable. Second, most other skill names are nouns (Body Armor, Paralysis Breath, etc. -- an exception being Mimic). But as a noun, the word "degenerate" does not fit at all. The in game description is that it uses unification and separation to form a new skill from pre-existing ones. "Degenerate" as a verb can sort of fit, though not well.
Is this just a poor translation, and is it a verb or a noun? A better term for what is being described would be "Recomposition".
